Unfortunately using this monitor is a little bit of a hassle. On a previous intel-igpu laptop I would occasionally get kernel panics when plugging in the monitor with a usb-c to displayport cord. When that was working, however, sometimes the screen would be organized incorrectly. It is a 4K screen--3840x2160--but apparently is managed by the software as two separate displays--each 1920x2160--left and right of eachother.

I tried this monitor again on a newer laptop, this time using an amd igpu. On wayland it seems to not work, but that might be addressed in kernel 6.1.5, as noted in this thread. In the meanwhile, I switched back to xorg and it works with some manual configuration in xrandr. Here's what I am running:

xrandr --output eDP --auto --pos 0x0 --output DisplayPort-7 --auto --pos 1920x0 --output DisplayPort-8 --auto --pos 3840x0

Note the following:

  • My laptop internal display is output eDP
  • The UP2414Q outputs are DisplayPort-7 and DisplayPort-8
