Sony A1 Deep Test: TVs that best show 4K HDR HD video

With the Bank of China version of PS4 Pro officially listed on June 7, 2017. How to make "good horses with good saddles" and choose a TV that supports 4K and HDR effects to make full use of the strength of the PS4 Pro, has become the most troublesome thing for high-end and core players. Coincides with Sony's announcement of the 4K HDR OLED TV A1 at the CES exhibition in the United States earlier this year, its outstanding picture quality and design, and its stunning screen sound field technology has attracted much attention. And we are playing a hardware evaluation room now also ushered in a 65-inch A1. Next, let us take a look at how powerful the A1 and PS4 Pro consoles are.

â–ŒSlice of living design style: simplicity and atmosphere

â–²A1 continues the design style of Slice of living, slim and mirror-like

A1 continues Sony TV's aesthetic style of “Slice of living” in recent years. The team of Sony Creative Director Tian Xinghong Chong intends to reduce the brand LOGO, eliminate the TV base to replace the backboard support, so that the front of the fuselage completely let the screen be located in the ultra-narrow frame, and the design that blends in with the environment is for film lovers and game fans. And other core users bring shocking visual impact. Regardless of whether it is placed on the TV cabinet or on the wall, the A1 matches the Nordic and other homes that promote minimalism. And the usual TV screens with bases are placed on the TV cabinet. The screen and the cabinet are at right angles. The stability of the A1 screen and the back of the host is maintained by the support rods. Therefore, the screen will be placed on the counter. An oblique angle, the advantage of this is to meet the stability of the triangle theorem, and the slight elevation angle with a not too high TV cabinet will have a more comfortable look. However, for those users who are paranoid, if you want A1 to be placed perpendicular to the living room floor, you can still use the wall-hanging method.

â–² A1 back design is also very simple

â–²rich interface, cables cleverly hidden in the narrow cloth backplane

Like the screen, the A1's back design is also very simple. Subwoofer, circuit board, 4 HDMI interfaces (HDMI3 supports ARC), 3 USB ports, fiber optic interface, RJ-45 network cable interface cleverly hidden in the narrow fabric backplane. This makes the back of A1 look very clean and refreshing. Not only looks good, but also plays a role in the management of the line, so that users worry about managing redundant cables are no longer troubled. There is a USB port on the side of the cover that is convenient for users to plug in and use. If A1 is placed on the TV cabinet, it is better, but if it is a wall, it is recommended to use a movable stand, otherwise the distance between A1 and the wall may be too narrow. Increase the difficulty of plugging. Of course, buying a USB extension cable is also a solution. A1's power button and other physical buttons are also set on the side of the host. For those who like to wall-mount the TV, it increases the difficulty of use. Fortunately, these deficiencies can be achieved through the remote control.

▌ True and natural picture quality, full high-definition video playback to restore high

OLED (Organic Light-Emitting Diode | Organic Light Emitting Diodes) is considered by the industry to be one of the most ideal alternatives to LCD technology. A1 is the only Sony device that has been introduced in 2007 after the world’s first OLED TV XEL-1. The year's technology precipitates a return to the great masterpiece.

A1 equipped with a new image processing chip X1 Extreme, real-time image processing speed than the previous generation X1 chip increased by 1.4 times, can give full play to OLED self-luminous, no residual image, wide viewing angle and other natural advantages. 4K sharp image processing engine PRO, Triluminos Trang phantom and Motionflow double speed drive make A1 even more powerful.

In order to test the effect of A1's screen, Xiao Bian specifically found a 4K source such as “Yellowstone Natural Wonders” to play through the A1's own player. The professional movie mode is used during playback, X-tended Dynamic Range is set to "High", brightness is adjusted to the maximum, and the remaining options are default.

â–² clear black detail and dark performance

â–² Scenes from the upper reaches of the river to the more natural ones

â–² Black level details and background are layered

From a practical point of view, as one of the most important features of HDR, A1's very wide dynamic range allows some natural color transitions from the upper stream to the lower stream. A1 did not digitally add color to the screen. Using a single word to describe it was “upright”, but it also took into account both the details of the black level and the clarity of the darkness. It was very commendable. Some reefs in the river bed are very dark, and the overall image of the black court gives a very pure feeling. It avoids the black point details and background being forced by the overlord to be forced into one.

▌ Exclusive Acoustic Surface (Screen Sound Field Technology)

Compared with the low-frequency reflex speaker technology used by Sony's flagship high-end LCD LCD TV Z9D, A1 boldly uses Acoustic Surface, which can even be described as “radical”. This is also the world’s first large-screen TV with direct screen sound. The A1 uses the entire panel as a sound source, so the screen can double as a monitor and audio device, truly enabling any previous TV product (including CRT, LCD, plasma, etc.). OLED) is difficult to provide the ultimate enjoyment of the unity of sound and picture.

▌ "Horizon Zero Dawn" measured: shock has not subsided yet again attacked

The highlight finally came, and Xiao Bian immediately used the PS4 Pro host to collaborate with A1. The protagonist of this test was to shoulder the technical display responsibility at the present stage of the PS4 platform, and it was able to exert the most powerful functions of the PS4 Pro. The screen was the most convincing. Horizon Zero Dawn.

From the PS4 first edition to the latest PS4 Pro, a significant change in host hardware performance has been achieved. The new GPU architecture supports 4K HDR display, which can improve the image quality. A1 TV supports Dolby Vision's HDR format Dolby Vision, HDR 10, HLG and other mainstream HDR formats. In the game of "The Horizon Zero Dawn", Xiao Bian has compared the HDR mode on/off status in the game screen options. It can be seen that when the HDR is turned off, the overall picture appears to be "rich" and the whole The color of the picture is lumpy. In particular, the figure's face is the most obvious, as if it is marked with a thick layer of foundation. With the HDR turned on, the contrast is significantly improved, shadows and details are improved by a level, and the overall picture is natural and more layered.

â–²A1 setting HDR mode setting (automatic)

â–² HDR mode (off), the screen becomes particularly rich, no layering

â–² HDR mode (on), the overall shadow and details are significantly improved, color reproduction is high, natural

The X-tended Dynamic Range is also Sony's flagship black technology. When the X-tended Dynamic Range option is high, the highlights and shadows of the protagonist's shoulders are contrasted. When the X-tended Dynamic Range option is low, the details of highlights and shadows are basically combined in one piece. A1's screen response speed is also excellent. Even if the mechanical creatures hunted by the protagonist run at a high speed, there are no visually noticeable smears on the game screen, and they will not be forced to make the screen deliberately to reduce smearing. The sharpness of the game has decreased and the clarity of the game has been maintained at a relatively high level.

Experience experience (Small series - Manatee up to):

In fact, before the release of "The Horizon Zero Dawn", Xiao Bian had experienced "The Horizon Zero Dawn" with some impressive 4K TVs and PS4 Pro at some game shows. The feeling at that time was already shocking. To be honest, I did not expect this time to use the A1 and PS4 Pro combination to play "The Horizon Zero Dawn", which will give me a more profound shock. Although Xiao Bian does not understand the knowledge of hardware technology, A1 is still almost impeccable in terms of its expressiveness through intuitive feelings. Thanks to the "Ocean Zero Dawn" itself, the game screen has been very well-made, and even a very detailed texture detail can be seen clearly on the 65-inch A1 screen. Especially after the HDR effect is turned on, the effect of the light source in the game will be even better. The light reflected by the surface roughness of the fine stone and the expressiveness of the black area under the dark scene are all truly restored.

Experience experience (Small series - light):

The effect of Horizon Zero Dawn on the A1 is striking. It is rich in colors and has a sense of layering. The shadows are particularly noticeable. After the HDR is turned on, the overall brightness is significantly enhanced, the contrast is enhanced, and the perception is comfortable. The surround sound is very immersive. In the 4K mode, the operation of the game almost does not feel delayed and the experience is excellent. To say that the current PS4 Pro's strongest partner is, it is undoubtedly A1.

â–² After the HDR is turned off, the color completely disappears, and the shadow is especially noticeable

â–² After turning on HDR, the overall brightness is obviously improved, the contrast is enhanced, and the look and feel is comfortable.

▌ "Uncharted 4" measured: Each frame of the picture can be used as a wallpaper

Speaking of the most representative PS4 game, of course, I have to mention “Uncharted 4”. The artistic design of the naughty dog ​​of the developer is amazing. Apart from the effects of the live action movie, the performance of music and sound is also very different. In the case of limited performance of the first version of the PS4, the screen of "Uncharted 4" has left a deep impression on many players. The combination of the PS4 Pro and A1's dual swords, let Xiaobian more look forward to. At the beginning of the game, the night scene is particularly large, but in the tacit understanding of the PS4 Pro and A1, the details of the dark parts of the game scene are still outstanding, the sharp contrast of colors, the realistic and delicate 4K HDR light shadow performance, effectively avoiding the previous OLED TV easy The common problem of "losing the details of shadows" is that each frame can be used as a desktop wallpaper. In the game, the static dialogue of the character can reach the level of the Hollywood movie. Once again, he has to lament the naughty dog's demeanor for the character's demeanor. It is indeed the industry leader.

â–² Through A1's image quality, it fully shows the power of demeanor capture, and the details of the dark parts of the night scene are still outstanding.

â–² After HDR is turned off, black paint is mixed, brightness and darkness are mixed together

The combination of A1's Acoustic Surface and Mysterious Seas 4 makes multi-channel technology truly a reality. The complex environmental sounds in the game, A1 is more than enough to handle. The subwoofer has a built-in subwoofer. The full 2.1-channel configuration allows the bass in the game to be more powerful and the mid-high sounds clearer and fuller. The screen sound field technology, by its very nature, is set by placing two sets of sound driving devices on the left and right sides of the screen, respectively, and the driving devices at different positions operate to “talk” the screen for sound. A1 will also make sounds from different positions on the screen, which will make the transformation of the entire stereo sound field more flexible and accurate, and may even follow the change in the position of the vocal subject. For example, the character's voice in "Uncharted 4" passes through A1. The audio system will change according to the distance and location. The presence and presence of sound in the spatial distribution completely surpass the standards that ordinary televisions can reach. The advantage of this design is that the spatial and the three-dimensional sensation of the sound will be more intense, and the player will feel as if the sound is rushing toward him. The sound source also seems to move synchronously with the trajectory of the track, achieving "synchronization of sound and picture" and a strong sense of presence. It can be said that the combination of the PS4 Pro and A1 makes the performance of the “Uncharted 4′′, a masterpiece of art work, even more impressive. This is truly a unique gaming experience.

▌ System interface is simple and easy to use

â–² system interface is simple and easy to use

A1 currently uses Android 6.0 operating system, according to previous official news, follow-up will soon be upgraded to Android 7.0 system through firmware. The A1's system interface is roughly the same as an ordinary TV box and Internet TV, but after the design of the Playstaion game console system interface, it is very easy for users to get started. Due to the integration of too much black technology, there are a lot of parameters that can be adjusted on the screen and sound adjustment. Whether it is watching video content or playing games, users can personalize their settings and present their ideal and favorite pictures and sound effects on the A1 screen.

â–²Cooperation with Hua Shu, rich online entertainment content

Sony has always maintained cooperation with Huadian, and online pan-entertainment content such as movies, TV dramas, and variety shows has a very comprehensive coverage. Of course, in order to make localization more thorough, Sony has also entered into in-depth cooperation with the most influential entertainment resource providers in China, such as Sohu Video, LeTV Sports, and QQ Music, and can fully meet the diverse entertainment demands of consumers of different ages.

▌ Final summary: Sony A1 sets a new benchmark for the future of OLED TVs

Sony A1 TV continues the minimalist design of high-end models of BRAVIA series TVs, combined with the latest technology of the new generation of 4K HDR image processing chip X1, Acoustic Surface screen sound field and other latest technologies, through the integration of object-based HDR dynamic image-by-image weight Plastic technology, 4K HDR 14bit smooth gradient, dual image database three core technologies, frame-by-frame analysis and optimization of the screen object.

Whether it is with the PS4 Pro, XBOX ONE S, NS and other next-generation host with, or to watch 4K Full HD Blu-ray movies, Sony A1 TV can get an excellent sound and picture experience. As long as economic conditions permit, for the next generation of gamers, high-definition movie enthusiasts, Sony A1 TV is definitely the most valuable product at this stage.
