I have several dozen DVDs ripped (uncompressed) to my hard drive. I'm wondering about the quality of a VGA connection between my HTPC and plasma monitor (opinions please). I have it hooked up this way, and everything looks great! I'm wondering about the resolution of VGA versus DVI, HDMI,Svideo, RGB etc. Right now I have a HualHead 450 Matrox video card and am using this. I cant find a card with HDMI output yet. My plasma has a plethora of HDMI, Svideo, RGB, but no DVI inputs. If I were to get a new video card what should I get....Is the current (VGA) set-up really that bad? I'm not planning to use the HTPC for any TV tuning, or TiVO type capabilities. The quality is really pretty good, but I'm new to video, and am looking for opinions/ options! Thanks for your advice in advance! BTW, I'm using a 42" Hewlett Packard plasma, and I love it! Is there such a thing as a video card with HDMI, or RGB (component) outs?

VGA from the computer is analog RGB.
DVI is RGB (DVI-A is analog RGB, DVI-D is digital RGB and DVI-I has both) and HDMI (which is digital only) can be YCbCr or RGB. Don't use the S-video connection unless it's the best connection your source has available.
I don't think anyone is selling HDMI computer video cards at this time. Anyone who wants to will probably wait until after Windows Vista is released (don't ask). You can use a DVI computer output to connect to your plasma's HDMI input by use of an adapter or an HDMI-to-DVI cable. I seem to remember someone selling a component output video card or one that could be made to output a component (YPbPr) video signal. That was a while back and I don't remember where I saw it.
One of the problems with computers as the source for video is that the video cards and motherboard VGA ports tend to clip black and white. Not all of them have this fault, but many of them do.
