I have Intel DG45ID board with two iiyama displays ( first 17zoll 1280x1024 ProLite E1700S; second 24zoll 1920x1080 Prolite B2409HDS ).
Automatically both are configured to the same resolution first 1280x1024 and second 1280x1024. The second screen looks ugly with this resolution.
If i configure it to use first 1280x1024 and second 1920x1080, first one will be blanc and show this message:
out of range
H.Freg 67.7 KHz
V.Freg 60.2 Hz
With working setting it has:
H.Freg 63.9 KHz
V.Freg 59.9 Hz

How do you configure it? You may take a look at http://intellinuxgraphics.org/dualhead.html
Thank you for your answer. I did some more testing with xrandr and it's working:
xrandr --output HDMI-1 --mode 1920x1080 --output HDMI-2 --mode 1280x1024
Before i tryed to use gnome-display-properties to switch resolution and checked it with xrandr to see if it set correct mode.
The strange thing is that g-d-p set same mode like xrandr do, but only thirst one do this "out of sync" issue.
Is g-d-p not the fronted for xrandr? I thought xorg btw. xrandr should prevent from setting wrong settings.
So it sounds like a gnome-display-properties issue. Unfortunately I'm not familiar with that.
