Hey!

As you can tell from the title, for some reason, on KDE Plasma Arch (CachyOS) one of my monitors is only showing at 1024x768 and labelled as "HDMI-A-1-unkown"

This Monitor is hooked up to my AV Receiver, which then goes into the PC via HDMI.
Monitor>AMP>PC

Works just fine on windows, and I use this passthrough for my Audio too (Which also isn't being picked up due to it showing as hdmi known)

Looks like maybe its not receiving the correct edid, as xrandr's highest output for the monitor is: 1690x1267 59.91*+

#

Not really sure how to get around this, I don't have Windows installed to grab the EDID from there, and really I don't want to head down that route

#

Okay, so ive just umplugged everything, and its now detecting my amplifier (its change the output name)

But still only 1024x768 and no sound

#

Restarted, now back to HDMI-A-1-unkown

Meh, just sac'd off 4k monitor passthru and went with toslink instead
