Sony A9S OLED TV 2021 Review – Best 4K TV Model

The Sony A9S Master Series OLED is an best smart TV that offers outstanding image performance in almost any form of content. It will create inky blacks for a perfect dark room viewing experience, like all OLEDs.

It has an almost instantaneous response time and an optional Black Frame Injection feature, which in fast-moving scenes results in visible motion. Compared to its predecessor, the Sony A9G OLED input lag is considerably enhanced, but variable refresh rate support is still lacking.

It also has no HDMI 2.1 ports and can’t show a 4k @ 120Hz signal, which could disappoint anyone looking for a TV to go with their PS5 or Xbox Series X. As is the case for all OLEDs, there are chances of permanent burn-in; but for most people who watch varied content, we don’t expect it to be a concern.

Pros:

  • Inky blacks.
  • Near instantaneous response time.
  • Exceptional reflection handling.
  • Wide viewing angles.

Cons:

  • Risk of permanent burn-in.
  • Might not get bright enough to overcome intense glare.

Design:

Style: The Sony A9S has a simplistic and compact design that looks almost similar to the Sony A9G OLED. On both sides, the borders are narrow, and it has a very short center-mounted stand, which may be a concern if you have a soundbar put in front.

Stand: The Sony A9S has a center-mounted stand that allows the TV to sit very close to the table, which ensures that if you put a soundbar in front, part of the screen might be obstructed. The 48″ stand’s footprint: 18.3″ x 10.1

Build Quality: The quality of build is excellent, almost similar to the Sony A8H OLED. It is made of a plastic and metal blend, looks very solid, and there are no visible holes. On the back panel near the sides, there’s a little bit of flex, but nothing that can cause concern.

Picture Quality:

Movies: This is the best TV for watching movies. Because of the almost infinite contrast ratio of the OLED screen, it can create inky blacks, and there is no blooming around bright objects since there is no backlight, which is ideal for viewing dark space. Without any objects, it shows lower resolution content well and can erase Judder from all sources. Sadly, the rapid response time allows the lower frame rate content to stutter.

TV Shows: For viewing TV shows, the Sony A9S is excellent. It has large viewing angles, so when seen from the side, you don’t sacrifice too much picture accuracy, perfect for those who want to wander around while watching TV. Its Android TV platform is user-friendly and has lots of mobile applications available. It has excellent handling of reflection, but does not become bright enough to overcome extreme glare. Unfortunately, particularly with static elements such as a channel logo, it’s susceptible to permanent burn-in.

Sports: For watching games, the Sony A9S is excellent. It has a nearly instantaneous response time and a Black Frame Injection feature, resulting in fast-moving scenes with almost no motion blur. It has wide viewing angles such that when seen from the side, pictures remain reliable, making it perfect for watching a big game with a huge number of people. It manages reflections incredibly well, but extreme glare will fail to overcome it.

Video Games: This is the best gaming TV to buy. To have a sensitive gaming experience, it has a fast response time and low input lag. It does not, however, support any innovation for variable refresh rate, and the refresh rate is limited to 60Hz at 4k. It has a contrast ratio of almost infinite, making it a perfect choice for those who enjoy gaming in the dark.

HDR Movies: For viewing movies in HDR, the Sony A9S is excellent. Thanks to its excellent color gamut and infinite contrast ratio, it can generate a wide variety of colors in the HDR material. However, because of its aggressive Adaptive Brightness Limiter, certain highlights don’t pop the way they should. There is also some stutter in the lower content of the frame rate. In the upside, in dark scenes, there is no blooming around bright objects so it does not have a backlight.

HDR Gaming: The Sony A9S is awesome for HDR gaming. It has low input lag, and behind fast-moving objects, its near instantaneous reaction time results in almost no blur trail. To create flawless blacks, the OLED panel has a virtually infinite contrast ratio, making it a great alternative for dark rooms. It has an outstanding HDR color range, but because of its aggressive Automatic Brightness Limiter, it can only pull out highlights in certain scenes.

PC Monitor: For TV use as a PC monitor, the Sony A9S is excellent. For optimum text visibility, it supports the most popular resolutions and can display proper chroma 4:4:4. It manages reflections well and has large viewing angles, such that even though you sit up close, the image remains correct on the sides. Unfortunately, for static components, such as a desktop user interface, there are chances of lasting burn-in.

Motion:

Response Time: The Sony A9S has superb response time. It’s nearly instantaneous, resulting in clear motion and almost no blur trail behind fast-moving objects.

Flicker-Free: Since there is no backlight, the Sony A9S doesn’t use PWM, but it is not flicker-free. The small dip in luminosity every 8ms is attributable to the 120Hz refresh rate of the TV.

Sound Quality:

There is a strong frequency response on the Sony A9S. It’s well-balanced, but there’s a lack of low-bass, so no deep, rumbling sound can be produced. Without adding lots of compression artifacts, it gets pretty loud, perfect for large or noisy areas.

The output of the distortion is mediocre. At modest volume stages, there’s mild distortion, but it increases dramatically as the volume nears peak. That said, it depends on the content, and it may not be noticed by most individuals.

Smart Features:

The Sony A9S runs on Android TV. It is relatively quick to use and runs very smoothly. When checking, we did not encounter any bugs.

The home screen has advertisements and recommended content. Using the Configure Channels Menu choice, you can opt out of recommended content, but there is no way to opt out of advertisement.

The platform for Android TV allows you access to the Google Play Store. There’s a wide range of apps, and most of them work very smoothly.

The remote control is the same as the Sony A8H OLED but with a brushed-finish silver tone. There are Google Play and Netflix quick-access buttons, and there is a dedicated Google Assistant call button. To check for content and get details like the local weather and time, you can use voice control. Using voice modulation, you can adjust things like the volume and input source, but not parameters like brightness.

Conclusion:

Overall, the Sony A9S Master Series is an outstanding TV. It has an almost infinite contrast ratio and absolute black uniformity in its OLED panel, making it a better choice for watching movies.

It is well suited to watching TV shows or sports as it well upscales lower resolution video, plus it has wide viewing angles so that you can enjoy with a number of people. To have an exceptional gaming experience, it has a virtually instantaneous response time and low input lag, it lacks VRR support, and the refresh rate is limited to 60Hz at 4k.
