Using 2 video cards (HDMI / S-video) in a Home Theater PC?

Hi,

I want to output both HDMI and S-video from a PC. I checked newegg and didn't find any dual hdmi/s-video cards. The only ones were dvi/s-video. Now if I use 2 video cards in the PC, what would happen? Would it work simultaneously?

Or do I set it to one or the other? Also, if parrallel, would this take a performance hit?

Thanks.

  1. I would suggest buying one card, the one with DVI and s-video, and using an adapter like this to get HDMI.

    Much cheaper and simpler
  2. If your mobo has the correct expansion slots you can run multiple video cards at once. Each video card can run a monitor or 2 for an extended desktop. Windows xp and windows 7 can mix and match most any vendors cards, windows vista will only work with multiple cards that can run the same driver. If your using onboard video very few cards can use both onboard and a video card at the same time.

    The easiest way to run 2 different tvs from one computer is to try to find 1 video card with all the outputs you need.

    But does this DVI to HDMI cause a loss in quality?

    I was thinking of using the HTPC as a gaming computer some times too.
  4. Nope, DVI and HDMI carry the same video quality. The only difference is that HDMI can also carry audio.

    Oh...that's interesting. Which brings up another question.

    Do HDMI video cards output sound in via the HDMI port? Or are they just using the video part of it and you would have to connect your audio output separately as with past interfaces?
  6. If you have HDMI as an output from the GPU, you can send audio over that connection.

    If you convert DVI to HDMI, there will be no audio sent.
