I am running KDE/X11 with two monitors.
Screen 0: minimum 8 x 8, current 2944 x 1280, maximum 32767 x 32767
DP1 connected 1024x1280+0+0 left (normal left inverted right x axis y axis) 380mm x 300mm
1280x1024 60.02*+ 75.02
...
DP2 disconnected (normal left inverted right x axis y axis)
DP3 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
HDMI2 disconnected (normal left inverted right x axis y axis)
HDMI3 connected primary 1920x1080+1024+101 (normal left inverted right x axis y axis) 530mm x 300mm
1920x1080 60.00*+ 50.00 59.94
...
VGA1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
Is there any way, I can alter the gamma value on my HDMI3 display only? DP1 looks nice, but the other display is too bright/washed out.
