sorry new to this, what adapter will achieve 120hz if I pair this with my oled tv?
Apple does not support 4k 120hz over HDMI 2.1. It’s a licensing issue that they’ll turn into a marketing gimmick in two years—Apple does not license 2.1 and they’re so stingy I bet they’ll try to make a special Apple cord that only they sell to do it.
On my M1 Ultra I have used adapters that should convert the signal from HDMI 2.1 to DisplayPort 1.4 via Thunderbolt 4 and Apple has what I can only assume is a software block, since it should be more than capable.
Meanwhile I can manage to get my GTX 1080 Ti, a 6 year old GPU, to send a 4k 120hz signal through DisplayPort to HDMI 2.1 on Windows. So Apple just sucks
