Sony's flagship OLED TV A1 evaluation 4K HDR game effect measured

As a new force in the Sony TV product line, the A1 adhering to the consistent "minimalist" art style of Sony products, does not pursue fancy, but at the same time highlight the texture of the simple. The integrated frameless design used by A1 makes it look like a complete screen from the front, and it has nothing to add to it; what's even more amazing is its ultra-thin body thickness, A1's screen body thickness. Only 7.8mm, as shown in the figure than the PS4 game box even thinner, and an iphone7 quite.

Sony, who has accumulated deep experience in industrial design, has tried new ideas on this product. A1 canceled the base used in traditional TVs, but instead used its back bracket to support the entire screen. From the side, compared to the television, The impression given by A1 is more like a drawing board filled with a feeling of nostalgic art; and in the selection of the red dot award for the highest award for the design industry in 2017, A1 has won the highest honor, and it can be said that it has won international recognition. The universal recognition in the design field.

In addition, it is worth mentioning that the A1 backboard bracket is not only a supporting role. When we doubt why its screen body can be so thin, the backplane bracket shows us the answer: support A1 functional components Almost all of them were designed into this backplane bracket, including X1 advanced chips that Sony is proud of high-end TVs and various functional interfaces. It can be said that this back bracket supports A1 not only in appearance but also in the inside. The ontology.

A1's backplane provides a wealth of interfaces, including:

4 HDMI interfaces;

1 audio interface;

1 digital audio interface

1 video and audio input interface;

1 cable television interface;

2 USB 2.0 interfaces;

1 USB 3.0 interface

1 network cable interface.

Among the HDMI interfaces, it should be noted that in the four HDMI interfaces, only the No. 2 and No. 3 interfaces support the 4K HDR function. So when you start to play 4K version of Horizon Zero with A1, but find that the HDR logo does not light up, it may be that you pick up the wrong interface.

A1 still uses the classic style remote control, and Sony TV's remote control also has a small episode, when you connect the PS4, you can directly use the remote control to operate the PS4, the remote control's "OK" and "return" corresponding to The O and X on the handle, but this is limited to the PS4's system interface, after entering the game can no longer use the remote control operation.

It can be said that as a game player, knowing the evolution from PS4 to PS4 Pro, the most significant change is the new GPU architecture that supports 4K HDR display. So if you let a player who wants the ultimate game screen choose a TV, I'm afraid that supporting 4K HDR is the most basic option, and finding a TV that can fully play out the potential of the 4K HDR screen of PS4 Pro can be said to be the ultimate aims.

4K HDR

As for HDR, how much this feature can actually improve the display of TVs has always been considered debatable, because on ordinary common TV, first of all, whether it can support 4K HDR, even if HDR is turned on, it is just like giving TV exchanges a display mode, but A1's performance in 4K HDR mode really surprised me.

We used the "Sky of the Horizon Zero" to test the contrast of the A1 TV HDR switch in 4K resolution and game mode:

From the comparison, it is easy to see that under the condition of HDR being turned on, the overall picture style becomes more realistic and the color transition is more natural. In the lighted environment, the performance of HDR is more prominent. The details of clouds in the sky above are shown in the figure above. It was also shown; when HDR was not turned on, it was obvious that the picture was less natural, had a certain degree of distortion, and lacked details.

HDR is also more visible in the details of shadows, especially in darker environments such as nights or caves. Some corners that appear to be chaotic in non-HDR situations can also reveal more details in the HDR state.

Zooming in on the image above, you can see that the moon lines with HDR on the left are displayed, and those without HDR are missing.

The difference between the effects seen by the above group diagrams is self-evident, and this is only the effect captured by the camera. The dynamic effect of direct viewing is even more obvious; I invited some colleagues to watch this test if they use a sentence. To summarize the feelings of the people, it should be:

"When I didn't open HDR, I thought that this picture was actually very good. After HDR was opened, I couldn't see the screen without HDR."

We were amazed at the improvement of A4's 4K HDR. It can be said that we got a different game experience than before; and A1's support for HDR is not limited to 4K mode. It will also be upgraded through firmware in the future. The way to support Dolby Vision's HDR format, Dolby Vision, together with the already supported HDR 10 and HLG, can be described as a common current mainstream HDR format, and people can not help but sigh about Sony TV's support for HDR.

Shadow details

The performance of shadow details may not be the focus of attention for mass players, but it is also particularly important for players who are pursuing the ultimate gaming experience. For example, when we enter into those dim places in many games, it is often due to the lack of details in the shadows.

For A1, its black screen performance is more pure, with the OLED has no backlight structure and self-luminous characteristics, but also to avoid the common light leakage problems of the LCD panel, so that the contrast between the screen looks more intense, details The performance is also more in place.

Dynamic smearing

With respect to dynamic smearing, it can be said that smearing is not a problem for this level of OLED TVs. The visible smears are almost invisible to the naked eye. On the TV evaluation website Rtings, A1 is on this parameter. Has also been given a full score, its response speed is only 0.2ms, far exceeding the standard of traditional LCD TVs.

Input delay

The input delay results from the calculation process of the TV chip on the screen. Under the same conditions of the hardware, the smaller the amount of calculation, the smaller the delay. According to the official introduction, Sony has made a balance in this regard, especially for the game mode to further optimize, in order to ensure high-quality at the same time low latency, restore the developer's intentions. According to the data given by Rtings, the input delay of A1 in the 4K gaming mode is 30.7ms, which is in the same level as the Z9D and X9300E that are the flagship products. In the actual play process, it is difficult to reflect the concept of dozens of MS, because even games such as "Tekken 7" and "FIFA17" that require rapid response and fine operation, they did not feel a significant delay.

Wide viewing angle

I personally have another big preference for OLED TVs, which is the wide viewing angle. Wide viewing angle is a very important attribute for home or party-used display devices. As a leader in OLED TVs, A1 is in this area. The performance is not too much, let the pro-test even if viewed from the side of the small angle, the picture color will not have obvious loss.

[Side shot]

We have carefully tested the other big selling point of A1. It is also the technology of sound and picture and screen sounding that has been shouted as the black technology. This technology allows the sound of the TV to be sent directly through the screen and can be accurate. Spatially distributed, like the DEMO that Sony demonstrated at 2017 CES, the bird flies from the left side of the screen to the right, and the sound track moves as the bird moves.

The principle of this technology is that two sets of sound drive devices are respectively arranged on both sides of the screen. When the drive devices at different positions work, A1 will also emit sounds from different positions on the screen. We have done similar tests using games and movies. From the sound, you can hear a clear sense of position. This kind of experience without using external speakers can also provide you with an on-the-spot experience. It can be said that it was difficult for previous televisions to reach.

It's worth noting that the screen is not the only place where the A1 can be heard. A subwoofer is also built into the backplane bracket (this bracket is just like a hidden arsenal), a complete 2.1-channel configuration. The big scene with grand music is even more shocking.

Horizon: Dawn

The HDR effect of "Horizon" has been compared before, and what has not been mentioned is that the details of the screen are displayed in the 4K+HDR state, such as the details of flowers and plants, which are clearly displayed one by one. Shade and Each branch of the flower is also displayed. Together with HDR's abundance of colors, the entire picture looks like a beautiful painting.

Uncharted 4

"God Sea 4" is indeed HDR's endorsement game, personally think that A1's 4K HDR's "God Sea 4" screen growth is greater than the horizon, when you open HDR, the overall picture color has increased by a layer, the screen style is more True, even the pictures taken at high speed are completely enough to be used as wallpapers. In terms of details, not only the scenery, but also the close-up of some character's clothes and expressions. The increase in picture quality in the 4K HDR mode may give you the urge to "play again and again".

The picture taken with the camera even at high speed is fine enough.

Final Fantasy 15

"Final Fantasy 15" is another HDR-supported masterpiece that we tested. After HDR was turned on, in addition to fuller colors on the overall screen, the highlights were also reflected in some of the dark and bright details.

Notorious: Second Son

In the PS4 Pro 4K game camp, there are also some games that do not support HDR effects. We used A1 to test PS4's infamous masterpiece, Infamous. This special-effect works supported the 4K resolution on the PS4 Pro through a patch. Let's take a look at the picture it shows on A1.

The Infamous, with its special effect, has been hung from the beginning of the game to the end, and the picture of the camera penetrating in high-speed motion can also make people feel the dexterity of this game in the special effects of the picture.

FIFA17

Sports games are game types that require higher input delays and response speeds. We used the football game FIFA17 when testing A1 and let it run at 4K resolution. Judging from the actual play experience, we did not feel any significant delays and slowed down the performance of smearing.

FIFA17 does not support HDR, but at 4K resolution, the details of this game are also fully reflected, such as the player's clothes pleated, and the turf looks very delicate and realistic.

Tekken 7

In addition to FIFA, we also tested the latest fighting game "Tekken 7" which also has high speed and delay requirements. However, on the A1 big guy, there is still no noticeable delay and smearing. You can see from below. Watch the game play process.

4K HDR movie

I tried the 4K UHD Blu-ray disc “Batman Wars Superman” and I also tested the effect of turning on HDR when I started the movie. Although the HDR will be richer after the color is turned on, it will be distorted and not as good as it is. When you watch a movie, the default is automatic, and when you play the game, the default is automatic.) All shots except the first one are taken with HDR off.

The 65-inch A1 is priced at 35,999. Although this may be a price that makes most people want to sigh, it still has the value of “one penny and one receipt” at this level of product. For OLED TVs, especially in the area of ​​Sony's expertise in picture quality, A1 allowed us to see the top-level effects of 4K HDR. With the addition of black technology such as artistic shapes and screen speakers, A1 became the The best choice in the field.
