Two ways to change it,
1. use Option IgnoreEDID
2. use Option NoDDC and Option MonitorLayout TMDS, NONE
With above two methods, you'll also need to provide the proper timings for
your panel, either from HorizSync and VertRefresh or from a Modeline.
Since there are some panels having problem with their non-native modes, the
driver uses the internal scaler inside Radeon chips (RMX - Ratio Matrix
eXpension) for these modes by default.
I'm not sure what kind of tearing you see with the playback on
[EMAIL PROTECTED], changing this may or may not help. You can also try to use
[EMAIL PROTECTED] mode (the native mode of your panel) and set the color depth
to 16.

Hallo Michel,
thanks for your reply, because my first attempt didn't reach the list.
I'd really like to use modes above 60Hz for video playback. Maybe
this is completly wrong, but to me it seems that video streams with
25fps have less tearing with 75Hz refresh rates.
But aside from that, I just wonderd why Windows can program those
mode timings, although XFree just seems to see the 60Hz modes from
DDC. That's why I included the DDC Information.
If someone wants to comment on my remarks about video playback, I'd
appreciate that.
Thanks,
Patrick
