DELL 5K Display (UP2715k) not full 5k resolution (tiled display)
Gnome-Shell/Mutter does only let me set the two tiled as independent displays side by side. I know from another bug 781723 that this works on NVidia binary and I also had it running that way. But I now switched to amdgpu with new a new Vega. I have tested fedora 27 and I have a testsystem. I would like to help to get this working.
I use a Dell 5K Display, which:
- uses two Display Ports (DP)
- and is handled as two 2560x2880 display merged to one 5120x2880 screen
