HDMI 2.1 brings auto low latency mode (ALLM) and variable refresh rate (VRR) gaming here demonstrated on a Samsung QLED TV with a new firmware update to add that functionality support to the Microsoft Xbox One X. For more information about HDMI 2.1 features for gaming see my other video. That VRR functionality of HDMI 2.1 can be considered similar to dynamic refresh rate technologies like AMD’s FreeSync and NVIDIA’s G-Sync which are now popular for gamers buying new gaming PC monitors and new graphics cards, but the target market here for the HDMI 2.1 is also for gamers to be able to enjoy those features on the 4K TVs in the future. So expect upcoming 4K TVs to support it, if not it even being added to the firmware of existing 4K TVs on the market (like possibly as part of an evt firmware update for this Samsung QLED 4K TV), and here also updated with the firmware of gaming consoles like the Xbox One X.
