Glass has always been specified as HDMI 2.1 but the ALLM function of that specification is still arriving in the rollout of the most recent software update.

@Exiled-in-HH yea my bad. i think i have a 2.0 cable that i use to connect the ps5 to the glass tv and am wondering if using a 2.1 cable will make any difference

Glass does not have a manual 'game mode'.
