Game Mode HDR Brightness

To show off the advantages of HDR, we recommend getting a television set that can output at least 500 nits of brightness.

While both of these television sets were able to surpass this minimum, the C1 is a little brighter overall than the A80J.

According to HDR tests done by RTINGS.com, the C1 can output 611 nits when you are using its game mode setting, which is 44 nits more than the A80J. The Sony OLED did outperform the LG OLED in select test scenarios, however.

Native Refresh Rate

The C1 and A80J both have a 120 Hz native refresh rate.

With the C1, you will be able to play Xbox Series X games at up to 120 frames per second in 1080p, 1440p and 4K as well as PlayStation 5 games at up to 120 frames per second in 1080p and 4K.

For Xbox Series S, you can play games at up to 120 frames per second in 1080p and 1440p with the C1. For 120 fps in 4K, you will need a HDMI 2.1 cable as the Series S only comes with a HDMI 2.0 cable.

With the A80J, you can play PS5 games and Xbox Series X games at up to 120 frames per second in 1080p and 4K.

When it comes to the Xbox Series S, you can play games at up to 120 frames per second in 1080p with A80J. As we stated above, you also need a HDMI 2.1 cable in order to play Series S games at 120 fps in 4K with this Sony TV.

Adaptive Sync Support

The C1 is the only OLED in this comparison to come with support for FreeSync, GSYNC and Variable Refresh Rate. While the A80J currently does not support any adaptive sync feature, it should be getting Variable Refresh Rate in a future firmware update.

For PC gaming, AMD graphic cards are compatible with FreeSync while NVIDIA graphics cards are compatible with GSYNC. For consoles, Xbox Series S and Xbox Series X (as well as the PS5 in the future) are compatible with Variable Refresh Rate.

For the uninformed, adaptive sync will remove any noticeable stutters and screen tears in games.

Input Lag

When you compare the same resolution and refresh rate combinations, the C1 has lower input lag than the A80J. With that said, the A80J is still a great television set in terms of latency reduction.
