Native Refresh Rate

The two Samsung 8K TVs have a native refresh rate of 120 Hz.

On the Q900TS, this means that you can play games at up to 120 frames per second in 1080p and 1440p by using HDMI 2.0 as well as up to 120 frames per second per second in 4K by using HDMI 2.1.

On the QN900A, you can play games at up to 120 frames per second in 1080p, 1440p and 4K via HDMI 2.1.

HDMI 2.1 is supported by the PlayStation 5, Xbox Series S and Xbox Series X.

Variable Refresh Rate is for consoles as it is currently being supported by Microsoft’s Xbox Series S and Xbox Series X. The PS5 is also expected to add support for VRR in the future.

Game Mode Input Lag

The Q900TS and QN900A are pretty much identical when it comes to input latency when you use the game mode settings. The differences are usually only a fraction of a millisecond apart.

With that said, both of these television sets are considered to very good for responsive gaming due to the low input lag.
