Everyone must have heard of the word HDR. Now many mobile phone cameras have added HDR mode, and HDR has gradually become synonymous with high image quality. However, HDR is not limited to photographing. The full name of HDR is High Dynamic Range, that is, high dynamic range. The higher the dynamic range, the more realistic the color restoration. Now that we understand this technology, we can see that HDR can also be applied to TV.
After we use devices that support HDR to produce content, we need terminals that also support HDR to restore the material. At this time, ordinary TVs are powerless to restore colors. HDR TV starts from here. It improves the picture quality and color restoration from three aspects of brightness, contrast and color, and restores the original material to the greatest extent, thus forming end-to-end high-quality broadcast. From the perspective of industry development, the popularity of HDR TV will be an inevitable trend.
Now it's our turn to play today's leading role in Skyworth 65G8210 true HDR version. This 65 inch Skyworth HDR TV is the world's first mass production HDR TV. The TV claims that the highest brightness has reached an amazing 1236 nits, and has a color gamut far beyond the ordinary TV. Today, let's see what's outstanding about Skyworth HDR TV.
Unpacking installation
Although we were prepared for the size of 65 inches, when we received Skyworth 65G8210, we were still shocked by the huge packaging box. Skyworth has used a large number of foam materials to wrap the TV in order to protect it from damage during transportation. The packaging is very solid and stable.
Skyworth's TV is composed of two all metal brackets. The surface is plated with a light golden luster. Its color is close to champagne gold. Although it is golden, it is not vulgar.
It is directly fixed at the rear of the fuselage by two thick screws, which is simple and convenient to install.
A layer of yellow adhesive tape is pasted on the frame to protect the frame from damage during transportation. We will tear off the adhesive tape after installation.
Appearance details
After removing the protective tape, we finally got a glimpse of it. After the bracket is installed, the size of the TV has reached 1455 × 318 × 893mm, of which the size of the body is 1455 × 83 × 841mm. With the ultra narrow frame, the visual impact is very strong.
The body and bracket of the machine are also light champagne gold, and the surface is treated with frosting technology. Although it is gold, it is not as vulgar as Tuhao gold, but it is more eye-catching.
There are many rivets on the back to fix the whole machine. The main circuit is concentrated in the lower part of the bulge, and the speaker is at the bottom of the back. The main parts of the fuselage are full of heat dissipation holes, so you don't have to worry about overheating after a long time of use.
Various data interfaces and entity keys are located at the bottom right, and the power interface is located at the bottom left.
The interface configuration of the machine is very rich, including three HDMI interfaces (4K HDMI 2.0, supporting MHL), one RF interface, two USB interfaces (one USB3.0, one USB2.0), SD card interface, network cable interface, AV input interface, CA interface, optical fiber audio interface, subwoofer interface, AV output interface, and audio output interface.
The physical keys are hidden on the back and only provide some basic functions. The remote control is the main operation mode in daily use.
The accessory is very simple, only including power cord, remote control, instructions, warranty and installation instructions. The remote control has a good shape and feel, and its functions are simple and easy to use. It integrates the remote sensing mouse function, which is convenient to use.
System experience
The machine adopts Kukai system 5.0, and the startup interface is small and fresh.
The body is integrated with a CA card slot, and the cable TV card can be inserted to watch radio and television programs.
You can use it after connecting to WiFi.
In addition to Skyworth's account number, you can also use QQ number to log in.
The first time it is turned on, it defaults to radio and television signals. We did not insert the CA card, so it was a snowflake. Of course, the Kukai system intelligently sets this interface to mute, without the snowflake noise of traditional TV without signal.
The design thinking of Kukai System 5.0 is relatively simple. All operations are not very simple and easy to understand. It is not difficult to get started. Middle aged and elderly people can also get started quickly.
The setting interface is also simple and easy to understand, so users can use it without making too many settings.
In addition to the three default picture modes, we can also set the picture parameters according to our own color preferences.
Unlike some hidden manufacturers, Skyworth has marked TV parameters in great detail, including screen categories, screen parameters, processors and memory. Among them, the biggest highlight is the 4-color 4K+resolution screen provided by LG, with a viewing angle of ± 178 °. LG also claims that the limit brightness of this screen has reached 1236 nits, supporting true HDR level display. In addition, the screen also uses the Local Dimming technology to spend the backlight on hundreds of independent lighting areas for brightness control, which has better black color performance than ordinary LCD screens, and the minimum brightness is close to OLED displays.
In terms of film and television resources, Skyworth has a large number of film and television resources in cooperation with Tencent Film and Television, including not only domestic TV dramas and films, but also American TV dramas, NBA games live broadcast, and some films released simultaneously with cinemas provided by Tencent Film and Television, which are sufficient for our daily watching.
Screen quality test
Maximum brightness
We adopted the 9 illuminance test and added two areas with higher brightness.
The maximum brightness appears at the middle two sides of the screen. The maximum brightness is above 900 nits, and the brightness at the center of the screen is about 840 nits.
In our test, the brightness of the screen left us a very deep impression. Its highest brightness reached an amazing 970 nits, the center brightness 840 nits, and the edge part brightness except the four corners also reached more than 650 nits. The brightness of the four corners was relatively low, but the lowest brightness was 505 nits. The overall quality of the screen is very good. The brightness of most areas is above 800 nits, and only the edges are slightly reduced. But for such a huge display panel, this has been done very well.
The important point of the HDR standard is that the average brightness of the screen should reach more than 700 nits. At present, the TV that really reaches this indicator is rare. Many so-called HDR TVs that use HDR as a publicity stunt show their true colors on this basic indicator. The highest brightness of the Skyworth G8210 screen has reached an astonishing 970 nits, and the average brightness is also more than 800 nits, far exceeding the HDR standard. It is truly a true HDR TV. Skyworth officials also added the words "true HDR version" when naming the TV, which is also painstaking.
Minimum brightness
We all know that the weakness of the LCD screen is that the black is not deep enough to perform the pure performance of the OLED screen in which the black does not shine at all. Skyworth has adopted the Local Dimming technology to solve the problem of black and white LCD screen, that is, the backlight lighting is divided into hundreds of independent areas. The backlight of each area is controlled separately, which can make the black display area not glow, and achieve the effect of looking like an OLED screen.
The screen is in a black background and hardly emits light.
Pure black background
Black and white far end
Black and white near end
Under the condition of 100% brightness, we use pure black pictures and black and white mixed color pictures to test. Under the pure black background, the screen has almost no light, and the average brightness is below 0.1 nit. In the black and white mixed color picture test, the brightness away from white is only 0.2 nit, and the brightness next to the white edge is only 0.5 nit. In terms of black performance, Skyworth G8210 is very outstanding, and it is not easy for the LCD screen to reach this diving depth.
Color gamut test
In our color gamut test, the screen performs well, with Adobe RGB color gamut of 79% and sRGB color gamut of 98%. This is an outstanding data in TV, which has reached the current level of smart phone screens, and has better performance than most TVs at the same price.
Photometric Gamma Test
In the photometric test, Skyworth G8210 has a very good performance in the gamma curve, which is very close to the standard 2.2, almost coincident.
Color restoration accuracy Delta E test
In the color reproduction test, the average Delta E score of the screen reached 3.44. The color reproduction is very excellent, worthy of being HDR TV, and its color accuracy has exceeded that of most computer monitors.
Let's take a look at the evaluation standard of Delta E. Skyworth G8210's score is close to that of a more professional monitor.
Skyworth G8210 has a very good performance in screen test. Its performance in color gamut, color restoration and brightness is very outstanding. Its highest brightness has reached 970 nits, which is far higher than the 700 nits required by HDR standard. It is very impressive. The overall quality of this LG original 4-color 4K display panel is really excellent. Except for the slightly high color temperature, it is almost impeccable.
summary
Skyworth G8210 true HDR version, as the first mass produced HDR TV in the industry, its color saturation performance is relatively good. In addition to slightly higher color temperature, it is almost impeccable. The screen provided by LG is very useful. In addition, the performance of the screen in brightness is far beyond ordinary LCD/LED TV. In our test, Its maximum brightness has reached an amazing 970 nits. It is commendable that the machine has such a high brightness, but the black diving is still very outstanding. With the help of Local Dimming technology, the black part has achieved the effect that looks like an OLED screen. I want to praise Skyworth's control ability.
As one of the few televisions that really meet the HDR standard in brightness, Skyworth G8210 has the advantage of far ahead of other brands in brightness, but it is not enough just to meet the standard in brightness. It also needs to meet the decoding ability of 4K HDR of up to 10bit to be called "true HDR". For this reason, Skyworth and the famous semiconductor manufacturer Ruiyu jointly developed the RTD2997H decoding chip, This chip is equipped with a 4-core 64bit CPU, which can perfectly process 60P 4K 10bit HEVC code stream. It is one of the chips with the strongest decoding ability in the TV industry at present. The ultra-high brightness 4K screen and self-developed decoding chip together form Skyworth, a "true HDR" TV that truly meets the HDR standard.
As a domestic TV manufacturer, Skyworth is ahead of many well-known international consumer appliance manufacturers and takes the lead in launching mass production versions of HDR TV. Skyworth's progress in supply chain and independent innovation is commendable. Skyworth not only obtained the original 4-color 4K display panel provided by LG for the first time, but also jointly developed the RTD2997H decoding chip with Ruiyu, successfully solving the HDR decoding problem, It paves the way for mass production of HDR TV. Skyworth has thus become the first manufacturer to mass produce HDR TV, taking the lead in seizing the market of HDR TV, which will help Skyworth catch up with and surpass the world-class manufacturers in the future competition of smart TV.
