Yeah, that's exactly what it looks like. I tried specifying HorizSync
and VertRefresh in xorg.conf and also a Modeline, but they don't seem
to make any difference. I got the data from my TV's EDID data.
Modeline, HorizSync, and VertRefresh are all defined under the monitor
section of xorg.conf right?
Section "Monitor"
Identifier "monitor"
# HorizSync 31-83
# VertRefresh 56-85
Modeline "1360x768" 86.96 1360 1480 1528 1774 768 778 783 817
-Hsync -Vsync
EndSection
Section "Screen"
Identifier "screen"
Device "device"
Monitor "monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1360x768"
EndSubSection
EndSection
