Which one is better, Konka TV k2 or r2?
Foreword
According to the latest statistics released by the China Health Development Research Center of Peking University, the myopia rate among children aged 6-15 in my country has reached 46.64%, and 46 out of 100 children need to wear glasses. According to authoritative medical clinical data, more than 50% of eye problems are caused by blue light.
As the protagonist in this review, Konka LED55R2 new frequency conversion ecological TV (hereinafter referred to as "Konka R2") will face this problem head-on with three major frequency conversion technologies. Among them, spectral frequency conversion technology is the unique optical anti-protection technology used by Konka R2. Blu-ray technology is said to not only eliminate a large amount of blue light from the backlight source, but also ensure image quality without causing color cast in the image. However, hearing is false and seeing is believing. The following content will show you what the author and I have seen with my own eyes.
In addition, while major mobile phone manufacturers are sparing no effort to create full-screen mobile phones with a higher screen-to-body ratio, TVs, as the absolute protagonist in the living room, seem to be half a beat slower than mobile phones in this regard. But this time, Konka R2, which appears in front of us with a floating screen, seems to be telling us that it is ready to take up the banner of full-screen TVs and intends to become the leader in the TV industry with products with full-screen designs.
I was quite surprised when I learned that Konka R2 is a TV with eye protection and a full-screen design, because before, the combination of eye protection + full screen seemed to be only available in a few recent TVs. It has only appeared on new mobile phones, so being able to have these two popular configurations at the same time makes Konka R2's winning chips even heavier. The rest depends on whether Konka can integrate these advantages into R2. This is also the purpose of our review.
Appearance design: The suspended design presents a full-screen appearance
Konka R2 adopts a new generation of suspended lamination technology design, which allows the TV screen to get rid of the constraints of the border and front frame, so it creates a screen that exists independently from the body. The advantage of this design is that the screen panel is separated from the body frame, thereby increasing the screen-to-body ratio to a certain extent. It is similar to the results achieved by some recent mobile phones that use sliding full-screen designs to achieve high screen-to-body ratios. It can be said to be very novel. .
According to actual measurement, the thickness of the body behind the floating screen is controlled within 7mm. If the thickness of the floating screen is added to the visual measurement of about 1.5mm, the actual thickness is very close to the official claim of 7.9mm. In addition, the author’s feeling after visual inspection is that the visual thickness is thinner than the actual measurement number, because under normal circumstances we will keep a certain distance from the TV when watching TV. When we are farther away from the TV, the thickness of the TV The visual perception will also be thinner.
Not only the floating screen, but also the design of the floating base is the finishing touch in the overall design of Konka R2. The brightest color of the whole machine is the silver base on the left and right sides of the bottom of the fuselage. The bottom of the base has a non-slip pad design, and the connection The combination of the fuselage and the flat surface makes the whole machine look very stable. The anti-slip pad makes it difficult to push it without using some strength, so there is no need to worry about slipping.
The speaker openings and decorative strips at the bottom of the front are presented in a gradient color, which is officially called chameleon coating. It is reported that the entire process is operated by a robot. The fully intelligent robotic arm can accurately control the color contrast. The black gradient mocha gold color matches the whole machine. The tone of low-key luxury is very harmonious.
Except for the installation space for the carrying handle, no exposed screws can be seen on the back of the fuselage. The stainless steel integrated molded fuselage realizes the full metal integration of the middle frame/back panel, and the upper part presents a whole The black back panel has a very shocking visual impact, and at the same time makes the product high in hardness, strong support, and dust-proof and moisture-proof. Although consumers rarely stare at the back of a TV after buying it, what I want to express here is that Konka's manufacturing process is worthy of recognition, it is simple but not simple.
The color of the remote control of Konka R2 should be a continuation of the mocha gold design on the TV, giving the plastic material a metallic texture. The streamlined body design is ergonomic, comfortable to hold, and the buttons are well laid out and provide feedback when pressed. Clear, the only thoughtless thing is that it doesn’t come with batteries for the remote control.
Three major frequency converters: the picture is "stable, accurate and ruthless"
As mentioned in the preface, the culprit that currently causes frequent myopia in children is blue light. Blue light refers to the part of visible light closest to ultraviolet, with a wavelength In the 400-500 nanometer range, light has a slightly lower frequency than ultraviolet light and is the most energetic part of visible light. Harmful blue light is blue light of 415-455 nanometers. It has short wavelength and high energy. It can directly penetrate the lens and reach the retina of the eye. It is the most harmful to the eyes among visible light.
Konka R2 uses a unique optical anti-blue light technology - spectral frequency conversion. Its backlight uses the latest developed optical anti-blue light LED lamp beads, which do not emit harmful blue light in the 415-455nm frequency band. Compared with ordinary LCD TVs, it achieves the effect of eye protection and no color cast.
Currently, in addition to OLED screens that do not emit harmful blue light, most mobile phones or LCD TVs on the market use ordinary eye protection modes. For example, after turning on the eye protection mode of mobile phones, the screen will obviously become yellowish. The optical anti-blue light technology of Konka R2 can not only eliminate a large amount of blue light from the backlight source, but also ensure the correct presentation of image quality without color cast. For example, in the video picture being played by Konka R2, the white and gray feathers of the seagulls are clearly colored, and the blue color of the seat is also restored accurately. There is no yellowing phenomenon in the picture. What is shown here is the "accurate" picture restoration of Konka R2. .
The next step is motion frequency conversion. Konka R2 upgrades MotionFlow through chip frequency conversion, and achieves more extensive dynamic picture compensation. To put it simply, it can make the moving picture look clearer, without blurring, trailing, shaking and other phenomena that affect the visual perception due to the movement being too fast.
For example, in the video shown in this photo, the little yellow ducks are huddled together and playing. Their body movements are relatively fast. Coupled with the frequency of feather movement, it is conceivable that if the frequency conversion is not supported, When viewed on a functional TV, this picture will hardly appear as vivid as the picture above. If you still feel that the picture is not as clear as you imagined, it may have something to do with the camera we use. You must know that shutter speed also determines the beauty of a moment. What is shown here is the "stable" picture of Konka R2.
Finally, it is light control and frequency conversion. Konka R2 uses the latest algorithm of the chip to perform backlight partition light control + screen partition dimming in real time according to the needs of the screen, achieving saturation and dynamic brightness compensation, and achieving a timely HDR effect. Among them, timely HDR technology can adjust picture saturation and dynamic brightness compensation through software, thereby realizing the transformation from SDR (non-high dynamic range image quality) to HDR image quality. In layman's terms, when Konka R2 plays ordinary movies (without HDR), it can also obtain a visual experience comparable to HDR effects. What is shown here is the picture of Konka R2 that is "really" clear.
As the saying goes, all talk does not mean practice, so we selected three image quality test charts prepared by Mr. Qian Yuankai, a famous Chinese digital imaging expert, to evaluate Konka R2. First of all, we selected the side view of 4K TV resolution for resolution testing. Through observation, we found that Konka R2 can still accurately identify the smallest text part, with clear line boundaries and distinct colors, and the black and white lines of the resolution table are clearly identifiable. , the color block details are restored accurately, and the overall visual effect is clear and sharp.
The second test picture is a 4K TV color performance and viewing angle test picture. Through observation, we found that Konka R2 has a rich sense of layering when presenting the spheres in the chromatic sphere, with even and soft transitions and no layering. Ring-like mutations with color. In the color distribution map, triangular zones can be identified in each of the six areas. In the color block diagram of the HSB color system, each color block is saturated and has no obvious gradation of colors. There is no obvious color shift or light and dark change when the viewing angle is changed.
In the third tone level restoration test picture, we found through observation that Konka R2 can distinguish all 21 gray levels in the spherical image, and there is basically no level skipping or merging phenomenon. The gray scale in the hierarchical distribution map has strong recognizability, and there is no step skipping or merging phenomenon in the gradient area. In the highlight gradation picture, the highlight gradation at 254-251 is faintly visible. This fully demonstrates that Konka R2 has excellent performance in terms of brightness and contrast.
In the four primary color test session, we selected a video clip containing red, green, yellow, and blue as the evaluation object. Through observation, we found that although the color of the lipsticks tends to be red, Konka R2 can clearly express the color number of each lipstick. The small green frog complements the lotus leaves on the road. The picture presents a harmonious and unique tone. It can be seen that Konka R2 still expresses green fully. The yellow parrot has clear and changeable feathers, which shows its analytical ability. The texture of the different blue silks and satins is still clear despite the shadows, and the transition between light and dark in the picture is natural and soft.
Sound effect: Ultra-thin body presents rich sound quality
Generally speaking, larger speakers often perform better in sound quality than smaller speakers. This is because the size of the speaker cabinet directly affects the sound quality. The sound field performance of music and the fullness of the sound. However, today's TVs generally pursue ultra-thin bodies, which makes the audio boxes hidden inside the fuselage become smaller and smaller, and the sound quality of the TV audio will also decrease. Due to current technological constraints, it is almost unrealistic to build larger speakers into an ultra-thin body. If you want to change the sound quality of a TV with an ultra-thin body design, Konka believes that improving speakers and sound units is the best solution. Kingly way.
Konka R2 has a built-in 30W high-power sound unit, which adopts an air-pressurized sound cavity and a speaker unit with a neodymium-iron-boron rare earth internal magnetic cavity design. Equipped with a silk dome tweeter, the bass adopts an independent large sound cavity, and the double basins resonate symmetrically to emit sound from the front and rear ends. It has a bass diffusion area that is three times larger than that of other speaker woofer units, and air pressurized conduction can release super bass below 60HZ.
Of course, it is impossible for Konka R2 to leave the speaker cabinet directly exposed to the outside, so we can intuitively see the position of the speaker hidden on the fuselage. One is the speaker mesh with gradient color design at the front and bottom, and the left and right sides of the front There is one speaker for each. The opening of the speaker on the back of the fuselage is more intuitive. The chrysanthemum-shaped opening in the picture is reserved for an independent rear bass. The heavy bass is diffused through reflection, thereby achieving a three-dimensional sound field effect.
It is worth mentioning that Konka R2 has Harman Kardon sound effect certification, so we can see the Harman Kardon faith logo in a prominent position on the front of the fuselage. This is because Konka R2 has been carefully designed and adjusted to meet the certification standards of the Harman Kardon brand in terms of the speaker's frequency response range, low distortion rate and high-fidelity sound quality. At the same time, the speaker system of Konka R2 has also reached Harman Kardon’s highest sound quality certification standards. Therefore, whether you are watching movies, chasing sports or listening to music, Konka R2 can satisfy your ears.
We used the mobile APP to collect the sound quality histogram of Konka R2. Through the shape presented by the sound test software, we can see that Konka R2 has powerful low-frequency dive, stable mid-range, not floating treble, and sweet treble. , accurate midrange, deep bass, in a word, transparent.
Content resources: There is more than just what you see.
Returning to the main job of the TV, I believe that good-looking is the most important thing. The appearance is one, the picture is the second, then the third should be the content. . At present, most TV sets in China have built-in deeply customized operating systems based on Android, and Konka R2 is no exception. After years of innovation and optimization, the Yiyou 7.0 system now brings massive content resources to consumers. This is why TV manufacturers are willing to choose to build systems based on Android. The reason is simple because there is a lot of content to adapt to.
The main interface of Yiyou 7.0 system is presented in the form of a flat waterfall flow. After connecting to the Internet, more personalized content can be intelligently pushed, thereby realizing a content model for thousands of people. At the same time, the Yiyou 7.0 system provides users with more open function customization, including function modules, applications and shortcuts that all support customization. If I want to understand it, this seems to be somewhat similar to the open source of the Android system. Operating a TV is like It is almost no difficulty to operate an Android phone.
Since it is a system based on the Android platform, it is not surprising that it supports many content platforms at the same time. We can see on the homepage that these include iQiyi’s Galaxy Kiwi, QQ Music, NewTV Laser, Content platforms such as CIBN Kumiao Film and Television, on these platforms, you can find almost any movie, TV series, animation, music and other content you want to find. In addition, the existence of the application mall is like the APP store in Android phones. Want to play games? Just come here and look for it.
Through experience, I found that the homepage of Yiyou 7.0 system is the page where I stay the longest, because here the system will recommend content that you may be interested in based on your usage habits. Take the popular TV series "Mother's Way" recommended on the homepage as an example. The show is currently being broadcast on Beijing TV, and the Galaxy Kiwi APP is also updated daily. This shows that Konka R2 can meet your needs for watching dramas.
Movies, as one of the best forms of entertainment, have a very strong demand on TV. For example, the author and I often watch movies on my mobile phone, and I have paid a lot of memberships for this purpose. However, the convenient advantage of mobile phones has sacrificed my visual experience. So if the TV can provide exactly the same content as the mobile video platform, will you still watch it at home with a mobile phone? I don’t think so. Judging from Tong Liya’s beauty alone, it’s worth seeing her on the Konka R2. The popular movie "Cohabitation in Time and Space" was just released a while ago, and Konka R2 is ready for you.
Recently, I discovered that the girls and boys in the subway who are holding their mobile phones and giggling are usually watching some celebrity reality shows. In fact, when I watch TV at home, this type of variety show takes up most of my time, so variety shows This content has become one of the advantages of Konka R2. First of all, it is more enjoyable to watch on a large screen than on a mobile phone. At the same time, because it is viewed online, there is no embarrassment of limited time viewing on a set-top box. Which issue do you want to watch on Konka R2? It's a choice, but the one-week restriction on the set-top box has already made me resentful. Maybe owning a Konka R2 for watching variety shows is the life I long for.
QQ Music, almost one out of every two people has this software installed on their mobile phone. Don’t forget NetEase Cloud Music. But this is not the point. The point is that music is also very important in our lives. It is the spice of our lives. There is almost no difference between the QQ music on Konka R2 and the APP on the mobile phone. Whether it is Jie Ge's MV or Xianrou's singing, it will make us feel familiar and familiar, because the operation is as simple as the click of a fingertip. Even a voice command "I want to listen to XXX's songs" can be done.
In addition to TV series, movies, variety shows, and music, what else do we want to experience on TV, and is it one of the most popular contents on mobile phones? Such a simple question, if you blurt it out, it must be a game! Mobile games such as King of Glory and Chicken Fighting have almost become a phenomenon. Although it is still unrealistic to experience such games on a TV, who says that small games cannot be attractive? You must know that games such as Landlord Fighting, Fishing, and Xiaoxiaole have occupied a place on the game list all year round. So it is not surprising that Konka R2 supports gaming experience. You only need to find them in the app store and download them to start your gaming journey.
Yixue and Children are put together because this can be a place for children to gain knowledge and happiness. With the three major frequency converters of spectral frequency conversion, mothers no longer have to worry about the problem of myopia in their babies. Konka R2 The content in these two sections can be watched safely by children, while adults can also obtain content such as parenting tips here.
The author has a selfish thought here. The animation "One Piece" and NBA player Wade are both my favorites. It is self-evident that they are both in their respective fields. The former is the leading work in the Japanese animation industry today, and the latter is the 03 golden generation that has started its last season. As the two who accompanied me through my youth, I want to put them here to explain the Konka R2 There are also rich animation resources and sports-themed resources, so maybe you can find your own beauty on Konka R2 like me.
Finally, it must be said that Konka R2 also supports the expanded gameplay of mobile phone screen mirroring as shown in the picture above. You only need to download the Yi Interactive APP on your mobile phone to realize the display of photos from the same mobile phone on the mobile phone and TV as shown in the picture above. status. In addition, when the remote control cannot be found, the mobile phone can also become a TV remote control. Of course, the same APP can achieve this. Therefore, there are more things to play in Konka R2 waiting for you to discover.
Summary:
Although the title "A full-screen TV that can protect your eyes is a good TV" may seem like a joke, but after several rounds of complete use experience, Konka R2 gave me the feeling that it does have Qualifies as an excellent TV. A product that can be called an excellent product can be easily achieved by more than just eye protection and a full screen. Konka R2 not only protects the eyes, but also makes the appearance more eye-catching and the picture quality brighter. Comprehensive is not just the screen, but also technological innovation and content resources. Therefore, I think Konka R2, a "full-screen TV that can protect your eyes and is a good TV", deserves the title.
How about the Micro Whale 55-inch 4k TV?
[IT168 Review] Since September 2013, the world’s first curved 4K LCD TV was unveiled at IFA (Berlin International Consumer Electronics Show).

MicroWhale W55C Curved 4K Smart TV Review – Packaging & Accessories
Due to the curved screen, the packaging box of the W55C is nearly 10cm thicker than the previous 55-inch "flat" model of MicroWhale. The material is still low-key plain cardboard, and the packaging format is the "top-on-bottom" two-stage design used by Micro Whale models above 49 inches.
▲The Micro Whale W55C packaging box has a two-stage design of “top and bottom”
▲The packaging box of Micro W55C has handle openings on both sides
In addition to the brand logo, customer service phone number and official WeChat QR code printed on the packaging box, energy efficiency and product information labels are also posted on the upper right corner and lower right corner of the front of the box. From the latter, it can be confirmed that the W55C, like the 40- and 49-inch models recently released by Micro Whale, is manufactured by TCL Overseas Electronics in Huizhou.

Instructions, read instructions carefully, read instructions carefully.
▲Three thick pieces of foam plastic can be seen on the front of the Micro Whale W55C packaging box
▲A support paper pillar of equal height can be seen on the back of the Micro Whale W55C packaging box
After opening the packaging box, you can see that the body and accessories of the Micro Whale W55C are "properly" fixed in the packaging box by three thick pieces of foam plastic and a support paper column of the same height. In this way, even if it is delivered by express delivery and logistics with "Chinese characteristics", the TV can be guaranteed to be in good condition to the greatest extent when consumers receive it.
▲The packaging box of Micro Whale W55C still has the pattern of making a whale rocking chair printed on it.
▲Micro Whale’s unique packaging box “transforms” into a whale rocking chair
In terms of the "transformation" of the Micro Whale's unique packaging box, although the W55C's packaging box size is larger than any Micro Whale model currently on the market. But there are still patterns printed on the box. After consumers simply cut and assemble it, a cute whale rocking chair appears.
▲The split-type standard accessory tray W of Micro Whale W55C
▲Standard accessories of Micro Whale W55C
In addition to the TV body that is split into two parts: the base and the screen, the packaging box of the MicroWhale W55C also contains a carton containing standard accessories such as a remote control, power cord, A/V adapter cable, manual, etc. Here is the old Let me briefly introduce some of the main accessories.
▲The standard power cord of Micro Whale W55C is still provided by Nanke Electronics
▲The plugs at both ends of the standard power cord of Micro Whale W55C adopt an inverted L-shaped design
The 1.5m power cord that complies with the 60227 IEC 52 (RVV) standard is still provided by Nanke Electronics, and the plugs at both ends adopt an inverted L-shaped design. In this way, when the TV is mounted on the wall and connected to a wall socket, the power cord can be avoided from being excessively bent and occupying adjacent jacks.
▲The standard remote control of Micro Whale W55C
▲The standard remote control model of Micro W55C is still BRC077
In terms of standard remote control, W55C also uses the same BRC077 as most models of Micro Whale. Because it is equipped with Broadcom's latest low-power Bluetooth (BLE) 4.0 solution, it still has 10m non-directional remote control capabilities and a standby time that is not inferior to traditional infrared remote controls when powered by 2 AAA batteries. .
▲The top of the standard remote control of MicroWhale W55C is integrated with a microphone for voice interaction.
▲The standard remote control of Micro Whale W55C adopts Broadcom’s latest low-power Bluetooth 4.0 solution
In addition to controlling the TV through buttons, the 12-button remote control also integrates a microphone for voice interaction on the top. In addition, on the back of the arc-shaped remote control, there is a horizontal shallow groove designed at the position of the index finger when holding it, so that it can better fit the different hand shapes of consumers.
MicroWhale W55C Curved 4K Smart TV Review – Appearance & Interface
In terms of appearance design, the MicroWhale W55C is in the same vein as the W49F released in May this year. The stylish and simple narrow-framed body is perfectly integrated with the elegant bridge base, showing the "rich, handsome" temperament that a curved 4K smart TV should have.
▲Micro Whale W55C is the same as W49F released in May this year
▲The matte black metal front frame is almost the same as the background color of the screen
Since the matte black metal front frame is almost the same as the background color of the screen, it is difficult to detect its existence when viewed from a normal distance. In addition to the long black strip area under the center of the bottom of the front frame, there is also a "breathing" indicator light that lights up when on/standby. The superposition of such multiple effects can give consumers a more "textured" visual experience.
▲The long black strip area under the center of the bottom of the front frame is equipped with a "breathing" indicator light
▲The two sides under the front frame adopt hole-like hollowing technology
In addition, although the two speakers of the W55C are installed in a "downward" manner, since the two sides under the front frame are processed with hole-like hollowing processes, the problem that is common on narrow-frame TVs due to the placement of the speakers is still improved to a certain extent. The difference in the material of the tabletop leads to the problem of reflection and distortion of the sound quality of the bottom-mounted speakers.
▲The dark gray and frosted metal bridge base of Micro W55C
▲The base of the Micro Whale W55C also adopts an external splayed and inverted Y-shaped design similar to that of the W49F
In terms of the supporting structure, the dark gray, frosted metal bridge bases on both sides of the lower body also adopt an external splayed and inverted Y-shaped design similar to the W49F. After the base pillar is inserted into the corresponding jack at the bottom of the machine body, it can be connected and fixed using the standard 4 hexagonal socket screws (1 spare) and L-shaped hexagonal screws.
▲The two base pillars are engraved with L/R marks, and the rhombus directions of the cross-section are also different.
▲The bases are spaced nearly 1.2m apart and cannot rotate, ensuring the stability and safety of the support to the greatest extent.
Since the L/R marks are engraved on the two base pillars, and the rhombus directions of the cross-sections are also different, it can effectively avoid mistaking the left and right order when installing the base. At the same time, the bases that are nearly 1.2m apart and cannot rotate may cause inconvenience in some cases, but this also ensures the stability and safety of the 17.2kg W55C to the greatest extent.
▲The black engineering plastic stepped integrated shell of Micro W55C
▲The back of the Micro Whale W55C body is designed with two strip-shaped heat dissipation slots of about 1m.
Next, let’s take a look at the back of the Micro Whale W55C. First of all, on the stepped integrated shell made of black engineering plastic, two strip-shaped heat dissipation slots of about 1m can effectively ensure the stability of this 55-inch curved 4K smart TV for long periods of time.
▲The product information label in the center of the back of the MicroWhale W55C body
▲MicroWhale W55C is still designed with 4 dedicated screw holes for wall mounting
Secondly, although it is a curved TV, the W55C is still designed with special screw holes for wall mounting on both sides of the LOGO and product information label in the center of the back case. Let me break it off here. The wall-mounting service fee officially recommended by MicroWhale is only ￥169 (including the rack), which is definitely considered "kind" among many TV brands.
▲All I/O interfaces of MicroWhale W55C are arranged in the square groove on the right side of the back of the body
▲The editor feels that the I/O interface configuration of MicroWhale W55C is still a bit "thin"
All the I/O interfaces of the W55C are arranged in the square groove on the right side of the back of the body.

Among the 30 types of videos with different video/audio encoding and encapsulation formats, only two uncommon ones cannot be supported.
▲Only two uncommon types of videos cannot be supported.
Since AnTuTu video test v3.0 mostly only tests videos with 1920x1080 resolution, the editor also downloaded 7 4K videos with different resolutions, video/audio encoding, frame number, bit rate and sound channels from the Internet. , play through the USB interface to test the capabilities of MicroWhale W55C.
▲MicroWhale W55C USB 4K video playback test
Through the actual screen shooting video, we can see that except for a piece of video that most devices cannot handle, "BT" AVC, 120fps, 100Mbps, DTS-ES, 6.1ch, MKV packaged 4K video has sound and no image during playback. Almost without exception, other 4K videos can be played, fast forwarded and rewinded smoothly on the W55C.
Summary: As the first curved 4K smart TV launched by Micro Whale, the W55C still has shortcomings such as fewer I/O interfaces, non-top-level hardware configuration, and the inability to adjust scene modes (when playing online videos). However, in the opinion of the editor, with its "sufficient" hardware configuration, "easy-to-use" software design, and "massive" content resources, the Micro Whale W55C, which only sells for RMB 4,598, is still one of the first choices to enter the curved 4K era. . Of course, if you have already planned to buy a curved 4K smart TV with a larger size and higher configuration, then the editor recommends that you buy it on September 30, when MicroWhale’s second 78-inch split curved 4K smart TV is released. Compare and consider it.
How about Hisense ULED TV? What are its special features?
Nowadays, there are more and more high-definition videos, and ultra-high-definition videos are becoming more and more popular. With the emergence of more and more high-definition and ultra-high-definition movies, traditional ordinary LED TVs can no longer meet the playback needs of movies and the audience's requirements for picture quality, so improving resolution has become something that every brand needs to do. Hisense’s new TV Hisense led55XT900X3DU is a ULED TV, which has improved picture quality compared to LED TVs. So how does the new ULDE TV perform?
ULED features: high color gamut/high contrast/high-speed response
In fact, the reason why Hisense ULED TV is named this way is not to compete with OLED. The "U" in ULED is the abbreviation of "Ultra" in English. Translated into Chinese, it means the familiar meaning of extreme and ultra-high, which means that the picture quality is better than ordinary products. Just saying that the picture quality is excellent will not leave a deep impression on users. In terms of specific performance, ULED is worthy of everyone's attention.
High color gamut See more colors
It adopts high color gamut LED backlight and is equipped with precise image color gamut matching technology, which can effectively improve the vividness and realism of colors, making the TV picture bright, vivid and lifelike, while providing more color performance and restoring the true vision.
High Contrast See more details
The use of backlight partition dynamic control and image enhancement technology can greatly improve the dynamic contrast of LED TVs, making blacks deeper, whites brighter, transparent and bright, and layers clear, reproducing excellent picture performance and presenting stunning details.
High-speed response See more clearly
Advanced backlight scanning technology is used to compensate for the lack of LCD response speed and improve picture tailing and jitter. Presenting clear and smooth dynamic pictures, while bringing users a more perfect 3D display effect.
ULED picture quality comparison Traditional LED TV is unsatisfactory
I believe everyone is most concerned about the picture quality performance of ULED. In the evaluation, we used Hisense’s ordinary LED TV LED50X1A to conduct a comparison test with this ULED TV. In the comparison test, we used two TVs to play the same 4K ultra-high-definition video. Since the former does not support the USB high-definition decoding function of 4K video, we used an external TV box to connect to the HDMI interface for playback. Through comparison, we can clearly feel the difference between the two.
4K benchmark test chart
In the 4K test chart session, we used the professional 4K test chart released by Professor Qian Yuankai for testing. Judging from the performance of the test chart, it meets the basic display requirements of 4K TV, with clear vertical and horizontal lines, and the smallest font size can be displayed clearly. In terms of color restoration effect, the triangle also appears as it should.
4K Ultra HD video test
Hisense ULED TV has a built-in USB3.0 interface, which can decode and play 4K ultra-high-definition videos. In the evaluation, the author used Hisense 4K test clips with a resolution of 3840x2160 and formats including MP4, MKV, etc., which can be played back smoothly without any lag.
Take a closer look at the appearance Rich gold body with new remote control
For TVs, appearance design is very important. To a certain extent, it also has a greater impact on users. The TV is placed in the living room, and users need to face it every day. The excellent appearance design often makes users fall in love at first sight. This Hisense LED55XT900X3DU ULED TV is more attentive in terms of appearance. Let’s taste it together.
Today's new TVs would be too embarrassed to greet users if they didn't have extremely narrow bezels. This Hisense ULED TV adopts a narrow bezel design that everyone loves. The dark green narrow frame looks fresh and elegant, has a marble texture, and the workmanship is also very exquisite.
The bottom frame of the TV is a stylish gold color that runs through the entire bottom of the TV, which can be said to be the finishing touch. Thickness control throughout the bezel is also excellent. In terms of the base, the TV does not use the previous rectangular base, but adopts a rose petal-shaped appearance design and is made of all metal, making the TV more fashionable.
In terms of body interfaces, Hisense ULED TV is also very complete. Including interfaces such as RJ45 wired network, VGA, component, USB2.0, USB3.0, TF card, CA CAM, etc. It can be said that it is enough for users to connect multiple devices, and it is very thoughtful.
As for the remote control, it continues the consistent style of Hisense TV. It adopts a new multi-function remote control, which although it looks small in size, is very rich in functions. Supports five-dimensional navigation buttons and can perform voice recognition. The built-in rechargeable lithium battery design allows users to charge the remote control directly using the included Micro USB data cable without purchasing a separate battery.
With the continuous development of technology, various brands are constantly launching new TVs. The new TVs are greatly improved compared to the old TVs in terms of appearance and performance. Hisense LED55XT900X3DU ULED TV uses ULED technology developed by Hisense itself. However, the price of Hisense LED55XT900X3DU is relatively high. It is about 2,000 yuan more expensive than an LED TV of the same size, and the price is about 10,000 yuan. If financial conditions permit, you can consider buying a Hisense ULED TV.
