Yeah, that's exactly what it looks like. I tried specifying HorizSync |
20 |
and VertRefresh in xorg.conf and also a Modeline, but they don't seem |
21 |
to make any difference. I got the data from my TV's EDID data. |
22 |
Modeline, HorizSync, and VertRefresh are all defined under the monitor |
23 |
section of xorg.conf right? |
