HDMI 2.1 Features Start Trickling into AV Gear
--------------------------------------------------
Gaming Features on the Way
Like eARC, gaming-related features “will be adopted more quickly” than other HDMI 2.1 features, Tobias said. Starting at January’s CES, he said, products will be announced with HDMI 2.1-certified gaming-related features such as variable refresh rate (VRR), quick frame transport (QFT), and auto low latency mode (ALLM) to reduce or eliminate lag time and otherwise enhance game play on TVs.
Microsoft has already downloaded firmware upgrades to add VRR and ALLM to the Xbox One, as has Samsung to some of its TVs, but the features haven’t yet been officially certified as HDMI 2.1-compliant.
