I'm really not sure a HTPC is right for the VPL-VW10HT. This is one of those devices with a 1,366x768 array and I'm almost 100% sure you cannot drive it up to that spec. as the internal scaler will take a VGA signal and scale it up to that full array. I was never fully satisfied with the picture and I used the g400 and I'm fully aware of how Sony releases new firmware...
here's the relevant part of the FAQ on the
www.bigpicturedvd.com site:
Connecting the 10HT to a home theater computer (HTPC)
You need a VGA to 5 RCA phono cable. See the cable section above fordetails.
The biggest problem with using a computer to play DVDs is thatthe Sony locks into 4x3 mode when it detects any of the standardcomputer resolutions, and you can’t select "Full"mode to fill up the screen. If you use a card that can handle non-standardresolutions (the Nvidia GeForce and the Matrox G200 & G400),and create a 1366x768 resolution, the Sony will effectively scaleit to 1024x768 and still lock to 4x3. There is some hope thatSony will change this with a new firmware revision, but for nowthere is no way to drive the whole panel at 1366x768.
However, if you have one of the above-mentioned cards, you cancreate an 1184x666 resolution, with the appropriate front/backporch settings so that the Sony will recognize it as 720p HDTV.You will need either the Matrox Powerdesk software, or a programcalled PowerStrip which allows custom resolutions on supportedcards. The Powerdesk program can be downloaded from matrox (
www.matrox.com ) if it wasn’tincluded with your install disks, and PowerStrip can be purchasedfrom Entech at

Here are the numbers you need to create the custom resolution:
