Sorry for all the pictures, I need the answers quick and working ones so this can work and I can start playing Arma haha! It shows a HDMI input and a VGA input on the back of the desktop. Does it require both? What's the meaning of VGA and HDMI? I'd like to get this up and running quick.
Only use one or the other connection, not both. The images show you using a VGA cable, but it's plugged into the onboard graphics port on the board. You need to plug into the outupts on the video card, you may need a DVI to VGA adapter or a DVI cable from the ports on the graphics card to the monitor.
