Hi everyone! I’m trying to get a HP EliteDesk 705 G3 Desktop Mini to work as a Linux media player for my LG smart TV. My TV only has HDMI input, and my EliteDesk only has Display Port output, so I’m using a (reported) 4k60hz DP to HDMI adaptor, with a HDMI 1.3 cable.
Specifically, I want to use my computer to play 4k content on my television. I tried using HDMI 4k60hz and 8k cables, with OpenSUSE Leap with Gnome installed, but that led to the maximum resolution being 640x480. I ended up trying the HDMI 1.3 cable and that did work for whatever reason.
I’m not a fan of Gnome, though, so I wanted to switch to KDE instead. I can’t get 4k to work there at all. It has installed just fine, and I can use the computer with my 1080p monitor, but whenever it attempts to switch to 4k on my TV, I get a black screen right before I can login by entering my password. And if it boots on my TV in 1080p, I don’t have a visible cursor.
reportctl afterwards doesn’t really show any errors.
I added inxi -Gxx as an image.
Any thoughts?
Thats very interesting.
Do you maybe know if your gnome system was using x11 and your kde one is using wayland? Wayland might be a bit stricter when it comes to following specs and not implementing hacky workarounds. (or it could always be a bug)
Oh and if you do try out other cables, give us an update. I’m curious if it will work.
