What model monitor do you have on your PC?
I know the monitor I have has a VGA, DVI and HDMI input. With this, I can use a standard HDMI cable. If you don't have an HDMI equipped monitor, but has DVI, you MAY be able to get an HDMI to DVI adapter. I say MAY because depending on the type of DVI connector, they don't all accept a digital signal - some DVI ports are analog only.
