Hi!
I'm trying to get my monitor to run at 4K (3840x2160) over either HDMI or USB-C using a DisplayPort adapter, but having no luck.
For USB-C/DP. I get no image when booting.
For HDMI, the system boots, but xrandr and the LXDE monitor settings app do not detect 3840x2160 as a resolution (maxes out at 1920x1080). I have used this monitor with this cable at 4K resolution on an Asus Tinkerboard also running lubuntu, so I feel confident that the monitor supports the resolution.
Does anyone have any pointers for either get USB-C/DP to work at all, or HDMI to detect 4k?
Thanks!
