What are HDMI 2.1 features?

Native 4K 120 FPS content viewing and fast response

4K resolution combined with 120 FPS at present provides the highest level of smoothness and clarity for video and game content. These capabilities coupled with next-generation games dramatically reduce input lag while significantly increasing response speed. This means that the delay between the screen and your commands will reduce, while the response time for pixels to change from one colour to the next also improves.

VRR for gaming
Video games often incorporate dramatic scene changes from sudden explosions to swift colour changes, which cause the frame rate to reduce drastically. VRR compensates for these changes by simultaneously matching the refresh rate to the frame rate of the game. The result is a reduction in stutter delay and screen tearing which together creates a smoother image. VRR is extremely important for seamless gaming, unlike films where frame rates are relatively stable (usually 24FPS).  

Auto Low Latency Mode (ALLM, also known as Auto Game Mode)

ALLM detects when a console is turned on and automatically switches the TV to game mode. Game mode reduces the delay between your inputs on a controller and the corresponding action that takes place on your TV.
