I'm building a new machine and although it won't be used specifically as a HTPC I want to have HDMI out to my projector so that I can display a video on occasion. Would I have to use a certain graphics card or is there some tuner and/or video output card that anyone could suggest? I currently have an ATI HD2400 (which the HDMI feature doesn't really work). I plan on using a nVidia 8800GT for my new machine's card. So it would probably be best if I could add some sort of output card in addition to the graphics card I have chosen. I'm not sure this can even be done, but I'm not running into any hardware browsing around the net that is fitting my specific needs. Any ideas?
