RockPro64 Linux Manjaro HDMI 4K

[mkne]

I doubt this would be the cause as you've said that it is fresh KDE install but in any case - did you check if the system has `xf86-video-fbturbo-git`installed?

Hi,

"xf86-video-fbturbo-git" was not installed. I installed it. I did have an effect... I lost Panfrost acceleration, and, the only resolution available to me was 1080. Uninstalled, Panfrost back, and 640x480 to 1920x1080 back in my list of available modes.  

Can I just confirm that the RockPro64 can do 4K from the HDMI port? I'm not chasing the impossible here? When I read the specs, it looked to me like it should with no problems... 

The N2 and Vim3 both run at 4K on the same monitor and wire... So, I guess this is something specific to the RockPro64.

Any other ideas....

Thanks,

Mkne
