The high-end Sony A9S TV is excellent for dark room movies because of its inky blacks, 120 Hz refresh rate, wide viewing angles, and excellent reflection handling. However, the ABL, lack of HDMI 2.1 and VRR, and high input lag aren’t great for gaming.
The Sony A9S TV is a high-quality, 48-inch 4K OLED TV that debuted in 2020. Thanks to its OLED technology, it produces deep blacks, good peak brightness, and life-like imagery.
The compact screen doubles as a speaker, and the TV’s sleek bezel design adds to its aesthetic appeal. Additionally, users can connect the TV to Alexa, Apple AirPlay, and Apple HomeKit.
The Sony Ultimate X1 processor can upscale low-resolution content to 4K, and for bringing out subtle details, the TV features a Pixel Contrast Booster.
The Sony A9S has four HDMI 2.0 ports and three USB connections but lacks HDMI 2.1 support and the ability to display content in 4K at 120 Hz. It has a low response time, but unlike the best TVs, it doesn’t have a variable refresh rate.
What Is Not on the Box
What the brand doesn’t always tell you…
our Verdict
The Sony A9S TV’s peak brightness (836 nits) doesn’t eliminate glare, and the ABL dims the screen often. No HDMI 2.1 support may deter Xbox and PS5 gamers, but it has four HDMI 2.0 ports.
The TV produces inky black levels (0.238% standard deviation) for dark room screening, and reflection handling is excellent in well-lit spaces.
Although the 1.8ms response time and 120 Hz refresh rate are fantastic for fast motion, the lack of VRR causes some screen tearing. Colors pop with the inf:1 contrast ratio, and bright objects don’t bloom.
The TV upscales DVDs well, and the voice control-enabled remote operates the seamless Android TV OS. While the viewing angles are wide, the tested input lag (10.3ms) is unsatisfactory for competitive gaming.

Reasons to Buy
Impeccable picture quality in the dark
The Sony A9S TV excels for nighttime movie marathons, delivering inky blacks with its inf:1 contrast ratio (which is the best we’ve tested) and incredible black uniformity (0.238% std. deviation).
Fairly bright
Its tested peak brightness (836 nits) ranks in the top third of all TVs we have tested, and it is suitable for versatile viewing conditions because its glossy display handles reflections effectively. (ref)
Fast response time and low input lag
Films and games with fast-moving sequences are smooth thanks to the 1.8ms response time. The tested 10.3 ms input lag ranks in the top third of our tested TVs, and casual gamers will find it adequate, but it may not satisfy competitive gamers.(ref)
120 Hz refresh rate
At 120 Hz, the refresh rate is ultra-responsive, with reduced motion blur during gaming.
Great off-center viewing
This TV is perfect for hosting movie nights with friends since it exhibits wide viewing angles, with colors washing out only after 54°.
Reasons to Avoid
Distracting ABL
Although the TV can get adequately bright, the automatic brightness limiter (ABL) frequently dims the screen, which can be distracting for daytime viewing.
No HDMI 2.1
Gamers won’t be able to experience 4K at 120fps due to the lack of HDMI 2.1.
No Variable Refresh Rate
Screen tearing issues could negatively impact your gaming immersion since there is no VRR
