Eh? All 2019 and newer OLEDs have full support for HDMI 2.1. They will be able to do 4k/120.
There is just a issue with the eARC not sending uncompressed audio.
Do they? It has been a while since I was looking (early 2019), but at the time OEMs were only supporting what they felt like. Some had high refresh rates and/or variable refresh while missing the other. Are they all full-spec other than eARC now?
