Hello,
with a fresh installed LibreELEC 9.0.0 on a NUC7I3BNK (via HDMI on 4K LG TV) the maximum refresh rate which is selectable with 3840x2160p is 30Hz.
I also tried to get some modelines with cvt and gtf and used them with xrandr but without success.
With Win10 and Kodi i am able to set higher values (e.g. 50 and 60Hz).
I would like to set the GUI to 3840x2160@50Hz.
Does anybody have an idea if this is possible or not?
Is this a intel driver limitation, a mode detection problem or a real hardware limitation?
Thank's for your help!
