Replying to your comment again to say the cable worked. I could buy this exact cable, and my OpenSUSE Leap/KDE computer now does indeed work with 4k60hz on my TV.

Sadly, the processor isn’t really up to the task. But it was a bit of a shot in the dark anyway, I pretty much just hoped it’d work. But 1080p does do well, and on YouTube I generally watch 1080p.

I’ll try xfce next to see how that runs.

It seems to be the other way around. I reinstalled Gnome yesterday to test the HDMI 1.3 cable thing, and XDG_SESSION_TYPE is Wayland. And I’m pretty sure my KDE install didn’t have Wayland.

I don’t mind spending another €20. I’m pretty happy with my little computer costing only €100, including RAM and SDD.

Oh, also I am pretty sure HDMI 1.3 does not do 4k at all. Either 1080 or 1440p was the spec limit.

I didn’t think so either, but in Gnome it (at least this cable) did, like I said. I could easily tell and it said so in the settings.
