Are HDTV's not able of EDID via DVI? That's how I fixed my problems
with my projector and not knowing the correct ModeLines. I checked the
xorg log and low and behold I found the correct Modelines that were
being returned by my projector as valid. I used that one for 720p and I
turned on Linear deinterlacing and lost all the crappy motion blur I
had been fighting with.<br><br><div><span class="gmail_quote">On 1/7/06, <b class="gmail_sendername">Steve Adeff</b> <<a href="mailto:adeffs@gmail.com">adeffs@gmail.com</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
