I have a Dell u3219q 32" and Dell p4317q with this issue. I'm trying to set 150% on the 32" and 125% on the 43", but it just goes to 200% and or goes blank. And things reset after every reboot, i.e. scaling goes wrong, monitor positioning changes, etc.
My workaround is to set fractional scaling on and 200% on both monitors, then go to the nvidia settings -> xserver display configuration -> advanced... and set the following: 32" ViewPortIn 5120x2880 ViewPortOut 3840x2160+0+0 Panning: 5120x2880 43" ViewPortIn 5760x3240 ViewPortOut 3800x2137+20+11 (or just 3840x2160+0+0 if you don't need underscan) Panning: 5760x3240 This gets the scaling as near as possible, but it resets after every reboot even if you save it in the /etc/X11/xorg.conf. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1870736 Title: [nvidia] Screen scaling 125% gives 200% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1870736/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
