Only 720p TV output?

I have an OLED model (I had the original prior) and no matter what method of input I use for TV every single game only supports 720p resolution, resulting in a highly pixelated picture which looks worse than the Xbox 360. The thing is, this is a 4K/120hz LG LED TV, and the HDMI cable supports 4K resolution. For the input, I have no fewer than 3 types of HDMI adapters (one being a 3rd party dock), and ALL of them only allow the games to project in 720p. The main adapter I use is the Apple HDMI Multiport adapter: I know it supports 4K/60FPS because it does so when my Mac and iPad are plugged in with it. Furthermore, for all three adapters including this one, the actual steam deck settings itself do show that the system is running at full 4K resolution and in full screen. It’s simply when I boot up a game, that the in game graphic settings never go beyond 720p.
