Native Refresh Rate

The A80J and A90J both have a native refresh rate of 120 Hz.

As a result, these Sony OLEDs can play games at up to 120 frames per second in 1080p, 1440p and 4K if you are using the HDMI 2.1 port.

You can also play games at 120 frames per second in 1080p and 1440p if you are using the HDMI 2.0 port.

On consoles, the PlayStation 5, Xbox Series S and Xbox Series X support HDMI versions of up to 2.1.

Adaptive Sync Support

The A80J and A90J currently do not support FreeSync, GSYNC or Variable Refresh Rate. All three of these provide adaptive sync, which helps remove any stutters and screen tearing when you are playing a game.

With that said, Variable Refresh Rate is expected to be added to both of these TVs through a future firmware update.

FreeSync is designed for PCs with AMD graphics cards while GSYNC is designed for PCs with NVIDIA graphics cards.

Variable Refresh Rate is designed for consoles as the Xbox Series S and Xbox Series X currently supports it while the PlayStation 5 should be adding support for this feature in a future firmware update.

Input Lag

In terms of input lag, the A80J and A90J are pretty close when you utilize the game mode settings.

According to tests done by RTINGS, the A80J has a slight advantage at 1080p/60 fps, 1080p/120fps and 4K/120 fps. On the other hand, the A90J has a slight advantage at 1440p/60 fps, 4K/60fps, 4K/60fps/HDR and 4K/60fps/4:4:4.

With that said, the differences are so small that you most likely won’t notice. Overall, both of these televisions should provide a very responsive gaming experience.
