This is a big miss for me. I can’t use my TVs 120Hz VRR mode without HDMI 2.1.

I realize the Xbox Series X is beleaguered at this point, but apart from playing games that are on Steam but not Xbox, I can’t see why I would prefer the Steam Machine.

After commenting i looked up the actual capabilities of the port and it turns out while the port is officially only HDMI 2.0 it actually still supports 120Hz, HDR and VRR anyway. So basically it only doesn't support Display Stream Compression for 144Hz and beyond.

I quickly tested this by connecting my PC running Linux with a RX 6800 to my TV (LG C4). 120Hz, VRR and HDR were all available.

At 4K? Or are you limited to a lower resolution due to bandwidth constraints?
