I wish to report that I have, at last, succeeded in getting my HTPC to display something -- anything -- on my Sanyo 30" widescreen HDTV. I am using an ATI Radeon All-In-Wonder 9000 Pro video card with a DVI port and a DVI-to-HDMI cable. So far, the only timings that I can get to work are:
PowerStrip timing parameters:
Generic timing details for 1280x720:
HFP=80 HSW=40 HBP=248 kHz=45 VFP=5 VSW=5 VBP=20 Hz=60
Linux modeline parameters:
"1280x720" 74.250 1280 1360 1400 1648 720 725 730 750 -hsync -vsync
I am experiencing some overscan (I think). Running Windows XP Pro and with Internet Explorer 6 maximized, I lose:
-- about half the width of the title bar of IE at the top
-- about 2/3 of the task bar at the bottom
-- in this forum, everything left of the "V" in the "AV Science" logo at the top of this forum window and about an equal amount from the right
If I try to use the Advanced Timing Options screen tools to shrink the screen width (by clicking on the size and position arrows), I immediately lose my picture and the Sanyo displays a no-signal screen saveer. I'm still pretty new to this, so maybe I am missing something obvious, but how do I get rid of the overscan without going into a configuration which my TV won't accept?
Insert here some witty quote or observation.
