First of all, I am new to Ubuntu and a total Linux noob so bare with me ;-)
I have two identical monitors, but only one is recognized correctly, the other one fails to show the correct screen resolution.
The cold facts:
- OS: Ubuntu 18.04 (community theme on wayland)
- PC: HP 8200 Ultra Slim (yes, yes I know, not the newest one around ;-))
- Monitors: 2 x Samsung S24C450 (24" screens)
These are the monitor stats:
- Monitor 1 connected via VGA works fine with screen resolution 1920 x 1200. The monitor is recognized by Ubuntu as
Samsung Electric Company 24".
- Monitor 2 connected via VGA to DisplayPort with max screen resolution 1680 x 1050. The monitor is recognized by Ubuntu as
Integrated Tech Express Inc 27".
The first thing I did was checking the cables and switched the monitors. The problem continued for the monitor that is connected via DisplayPort.
I have googled around, but not really with any luck. I have looked for BIOS versions, and DisplayPort versions (1.1a), but no results that made any sense or could help in trouble shooting.
I changed between the different Ubuntu themes on the login screen, but were not able to change the screen resolution to a higher one than 1680 x 1050.
I have looked in terminal with
xrandr and got the following result:
Screen 0: minimum 320 x 200, current 3600 x 1200, maximum 8192 x 8192 XWAYLAND0 connected 1680x1050+1920+0 (normal left inverted right x axis y axis) 600mm x 340mm 1680x1050 59.85*+ XWAYLAND1 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 520mm x 320mm 1920x1200 59.88*+
I can see that the terminal results show the same resolution as what I can set in the GUI, but that's it.
What can I do?
Does anyone have some ideas?
Thanks for any help and replies in advance.
