You should have no need of gtf or mode creation with 620 graphics. Mode creation
via xrandr is an anachronism. X knows very well how to auto generate modes when
provided with needed specs. If EDID, the usual source for the data, is broken,
then provide the specs via:
Yes, EDID is wrong and does not show 3840x2160 warranted by Samsung for UR59C
32".
/etc/X11/xorg.conf.d/50-monitor.conf
containing the horizontal sync and vertical refresh rates for your display,
e.g.:
Section "Monitor"
Identifier "Default Monitor"
HorizSync 28-85
VertRefresh 50-100
Option "PreferredMode" "3840x2160"
EndSection
This has no effect but I suppose the problem is due to the 2 screen
configuration. So I have tried replacing Identifier with :
Identifier "HDMI-1"
But it is not better...
I have put in https://paste.debian.net/1203873/
the content of .local/share/xorg/Xorg.0.log
It seems that the Modeline 3840x2160 is recognized, but the 30hz
limitation is not expressed.
Acer swift5 specifies 3840x2160 but with a 30hz limitation, no more
frequency.
Thanks you very much
