The A80J and X90J are both television sets that were released by Sony in 2021. So, which one of these is better when it comes to gaming on the PC, PlayStation 5, Xbox Series X, Xbox Series S, Nintendo Switch and other systems?

You can find out in this comparison guide between these two new Sony TVs.

Quick Summary

When compared to the Sony X90J, the Sony A80J features a better contrast and slightly lower input lag. The A80J is also the only one of these televisions to feature a wide color gamut.

With that said, the X90J can output a brighter image when using HDR, which makes it a little bit more suitable if you are playing games in a very bright room.

Both of these sets support HDMI 2.1, 120 frames per second, Dolby Vision and HDR10. Sony should also be adding Variable Refresh Rate support to these two TVs in the future as well.

Game Mode HDR Brightness

According to tests done by RTINGS.com, the X90J is able to reach a very good 775 nits of brightness when you play a HDR videogame using the TV’s game mode setting. That is brighter than the A80J, which is capable of outputting at 567 nits under the same scenario.

Native Refresh Rate

These two TVs have a native 120 Hz refresh rate as you should be able to play PC, PS5, Xbox Series X and Xbox Series X games at 120 frames per second natively at 1080p and 4K. The 1440p resolution for these sets is limited to 60 fps, however.

Adaptive Sync Support

The A80J and X90J currently do not support FreeSync, GSYNC or Variable Refresh Rate.

With that said, Sony is expected to add VRR support for the A80J, X90J and PlayStation 5 in the future through firmware updates.

The Xbox Series X and Xbox Series S already supports Variable Refresh Rate to reduce stutters and screen tears.

Input Lag

According to tests from RTINGS.com, the A80J features slightly lower latency than the X90J when you use the game mode settings for both of these Sony televisions. Both are considered to be good in terms of providing responsive gaming experiences at the 1080p, 1440p and 4K resolutions.
