Hack and Tricks

TODO PS341WU have totally broken EDID Modes for use PIP and PBP

Add modes for PIP (CVT 1.2 "Reduced Blanking" timings)

xrandr --newmode "1792x756_60.00_pip"  87.38  1792 1800 1832 1872  756 764 772 778 +hsync -vsync

xrandr --newmode "2048x864_60.00_pip"  113.51  2048 2056 2088 2128  864 875 883 889 +hsync -vsync

xrandr --newmode "2304x972_60.00_pip"  143.04  2304 2312 2344 2384  972 986 994 1000 +hsync -vsync

Add two modes for PBP (CVT 1.2 "Reduced Blanking" timings)

xrandr --newmode "2560x2160_60.00_pbp"  351.96  2560 2568 2600 2640  2160 2208 2216 2222 +hsync -vsync

xrandr --newmode "2560x1080_60.00_pbp"  175.98  2560 2568 2600 2640  1080 1097 1105 1111 +hsync -vsync

Assign to DisplayPort-0

xrandr --addmode DisplayPort-0 "1792x756_60.00_pip"
xrandr --addmode DisplayPort-0 "2048x864_60.00_pip"
xrandr --addmode DisplayPort-0 "2304x972_60.00_pip"
xrandr --addmode DisplayPort-0 "2560x2160_60.00_pbp"
xrandr --addmode DisplayPort-0 "2560x1080_60.00_pbp"

Not sure if it's the right place to ask, but the monitor brightness is weird in that even with a value of 0 (out of 100) it is still sometimes too bright for me... For my other monitor, if I turn the brightness to 0, it would practically be pitch black. Unsure if msigd could turn it darker than the value of 0.

you can use xrandr for it. example : xrandr --output DisplayPort-0 --brightness 0.3
