[Bestbuy618 Home Appliance Channel] Although Hisense has shown 8K TV as early as 2016, 2018 is regarded as the first year of 8K production. The Hisense 8K Pro dual-screen TV is the first Hisense 8K TV to be officially mass-produced this year. There is a saying that “not a sound is already a sound amazing,” Hisense or hold back a lot of big moves for so long. Hisense 8K Pro dual-screen TV As the name implies, this TV has two screens.
Above this large screen for 85 inches, the screen is suspended relative to the bezel, as seen in the previous Hisense U8E and other products, the biggest benefit is to bring ultra-narrow bezel, while ensuring sufficient structural strength. The small screen below is a 28-inch full-time assistant screen.
This 28-inch screen displays the time, weather, and other information when not in use. When there is a message push, it will be displayed directly to this screen, including news subscriptions, life type push, trip reminders, and so on. When there is a voice interaction and other operations, in the past, the interactive content will be directly displayed on the TV screen, causing some obscuration of the screen, but now, the interactive information is moved to this small screen, such as: wake up the voice assistant, voice search drama, query people, and so on.
When the main screen is closed, this small screen can function as a control panel, similar to how a TV can function as a smart speaker, displaying the interface for playing music. With the advancement of the intelligent system, the future of the TV to become the center of home interconnection, then this small screen can also develop more ways to play. When not turned on, I assumed the lower half of this is the screen, but in fact only a small piece in the middle.
If the “assistant screen” can cover the entire area, the visual impact will be greatly enhanced. Hisense is the official sponsor of the Euro Cup, and this TV is also a limited edition of the Euro Cup, with only 1000 units available worldwide, each with an individual code.
To assess the clarity of a display device, consider not only the absolute resolution value, but also the PPI (the number of pixels per inch). We frequently use 23-inch 1080P office monitors with a PPI of 96. This 85-inch 8K TV has a resolution of 7680 4320, which is four times that of a 4K TV, and a PPI of 104, which means that if you look at the TV from the same distance as the monitor, this TV is clearer. When you switch to a normal TV viewing distance, you won’t notice any graininess.
The 8K TV’s are bursting at the seams with detail when playing native 8K video. Of course, at the moment, the native 8K content is still relatively small, basically some demo films, most users are still the most exposed to network sources, the quality is better 4K, followed by 1080P, and some 720P.
The majority of current industry products are still in the second generation, and the third generation of the enhancement point is primarily in the more delicate 4K to 8K optimization. We will be a section of 8K demo film, transcoding and reprogramming to 4K and 1080P definition, with a video record of the real clarity of performance.
The actual test discovered that, at normal viewing distances, 4K and 1080P sources perform nearly identically to 8K sources. 8K should have nearly no loss in image detail, while 4K and 1080P should have almost no loss. Only when you stand at a distance from the monitor can you see that 8K is going to be sharper in terms of edge detail.
HDR is a cliché; in the 4K era, HDR was abused, but any TV that claims to “support HDR” The support they claim is only “processor support HDR decoding,” which is meaningless because there aren’t many 4K TVs that don’t support HDR decoding. True HDR, on the other hand, is the screen itself meeting the HDR standard, which is a hard indicator is the brightness.
We frequently see “HDR400”, “HDR1000”, and other signs, HDR followed by the number, that is, the display device can achieve the highest brightness, HDR level is precisely according to the brightness to divide. In order to distinguish from the simple “8K decoding”, Hisense first proposed “8K HDR screen”, that is, the screen to achieve HDR standards, rather than just processor support.
(The lab environment can reach 2500 nits.) What is this concept? At the moment, there are only a few TVs that exceed 1000 nits, which are primarily flagship products from major brands. Currently, the highest brightness value in 8K TVs is 2500 nits.
The answer to the question “what are the benefits of high brightness?” is HDR. For example, the lighthouse’s brightness was measured at 1018 nits while playing this HDR1000 demo. Of the various TVs we’ve tested previously (including major flagship TVs), the highest has been 700-800nit, with Hisense’s 8K TV coming close to the 1000nit value required by the source. Last year, Hisense first launched a stacked screen TV, which improved the contrast and black field performance of LCD TVs to a level close to OLED through the addition of a new light control panel.
TV contrast, peak brightness, black level, and even color are all closely related to the backlight. You might think that the backlight isn’t important, but Sony is one of the companies that vigorously promotes it. Hisense 8K Pro dual-screen TV has the most number of backlight partitions in an 8K TV, reaching 1694.
Backlight partitioning is not to do more than you want, the first is to consider heat dissipation, and the second is to accurately control each backlight area. Regarding heat dissipation, you will notice that all current 8K TVs are thicker, to ensure that heat dissipation is an important reason. Hisense employs a chip control platform based on its own light control algorithm and 112 backlight control chips to form 14 groups of independent core control clusters in light control.
In layman’s terms, it’s equivalent to installing 14 independent graphics cards on the TV so that it can perform precise light control for each area.
How can the average consumer determine the benefits of multi-zone backlighting? It’s simple: turn off the lights and play videos or pictures with a lot of black images, preferably in motion. For example, while playing the HDR video shown above, this TV presents a very high flame brightness, while being able to keep the surrounding black parts deep as night, without seeing a trace of backlighting. And, the lit area can follow the moving object without trailing.
We’ve done a lot of this testing, and there are three issues with TVs in general.
1 is unable to do in addition to moving objects in the region all dark down, the screen gray, often a glance can see the traces of backlighting; 2 is a serious trailing of moving objects, or even a broken situation; 3 is a serious flicker of moving objects, the white screen is bright and dark. Actual test found that this TV in the test process, in addition to the white area, the rest of the screen to keep all black, black is very pure, as if the backlight is Furthermore, when the object movement is gradually accelerated, the white area still has no trailing, no residual shadows, and the light control performance is very satisfactory. This year has been very interesting, as many cell phones have used high refresh rate screens, i.e., 90Hz or 120Hz and above. Indeed, many high-end televisions have long been 120Hz.
120Hz also means that the TV can display 120 frames per second, which is twice as many as 60 fps. Of course, it must be combined with software, specifically the MEMC algorithm, to increase the standard 24 fps video to 120 fps by inserting frames, completing the hardware and software combination. Hisense offers three levels of smoothness to choose from: “clear,” “standard,” and “smooth.” For example, in the video above, 4K 60 fps, the picture is full of text and texture details, whereas in most 60Hz TVs, almost all have dragging shadows, making it impossible to see the picture details when playing. However, the default “standard” setting on this TV has no trailing at all, and the motion picture is extremely smooth, with clear lines on maps, mountains, rivers, and lakes.
This is also true if the “smooth” option is chosen. If you disable the MEMC by turning off the dynamic option, the motion picture will be dragged.
Typically, the TV comes with mediocre sound because it is limited by the slim size of the TV and cannot fit a larger sound unit. Many audiophiles prefer to build their own multi-channel audio, but the Hisense 8K Pro dual-screen TV is an exception: 110 watts of high output power, 8 channels, 14 speakers, 6.8 liters of large volume cavity….. Dolby Atmos support is available, making this a very luxurious configuration.
In addition to four front exit sound speakers, two multi-channel sky speakers used to create surround sound, and two woofers, we also have a soundbar in our hands, and the sound that comes with this TV is surprisingly better than the soundbar. Mostly reflected in the sky sound to provide more excellent surround sound, low-frequency volume is more adequate, the sound field is broader, no external audio, this is a set of independent home multi-channel audio configuration.
It’s not as simple as using an 8K panel with 8K TVs. Higher definition, lower panel transmittance, chip arithmetic, and a backlight control system have all raised the bar. Hisense is a domestic manufacturer, in the independent chip, independent backlight on the strength of deep technical accumulation, which is why Hisense’s first mass production of 8K TVs have such excellent performance. With an unprecedented high peak brightness, ultra-fine zoning backlight, smooth 120Hz, and the assistant screen for future home interconnection, such strong product power, Hisense 8K Pro dual-screen TV is indeed called the representative of the top 8K TVs at CES.
The most important thing is that Hisense will release six more image quality and AI chips in the next two years, and the application rate of independent image quality chips exceeds 90%. Perhaps we are witnessing the transformation of domestic television into the world’s top flagship.
