Failure to use 3840x2160 30hz with Intel 620 chipset
I have a problem when trying a 4K display with Acer swift5. They say
that 3840x2160 30hz is supported...
When I try (under bullseye) :
gtf 3840 2160 30
xrandr --newmode "3840x2160_30.00" 339.57 3840 4080 4496 5152 2160
2161 2164 2197 -HSync +Vsync
xrandr --addmode HDMI-1 3840x2160_30.00
xrandr --output HDMI-1 --mode "3840x2160_30.00"
the PC crashes (all is black, need to power off).
Did anyone success in similar case..?
Thnaks for any help.
