  1. Hey everyone!

    I know this might not be possible but I'm wondering if you can uses two SLI cards, but use the on board port to push the output video. I have two 9800 GT cards with dual DVI connections. The motherboard has a HDMI output and I would like to hook this pc to my HDTV. I can hook the the on board port just fine but the system doesn't use the graphic cards at all. Is their a way to make the graphics cards work when their ports are not in use? Thanks in advance!

    Specs
    2 X 9800 GT
    1220 modular power supply
    Dual core AMD 3.2 GHz
    2 X 500 GB hardddrive
    4 GB of RAM

    obviously it wouldn't work. you cannot expect the graphic card to output the display to onboard HDMI port right? it's time for DVI to HDMI converter.

    like nismo said you need an adapter or choose between onboard or dedicated graphics. you cannot use the motherboards HDMI output if onboard graphics is disabled.
