So, I just bought a 690, but I only have Hdmi and VGA. I m too lazy to go to the store for a dvi cable which is as good as an HDMI. Can I use the full GPU s potential while being connected to the monitor through the mobo? I do have I GPU multi monitor setting turned on, but when I set the 690 as the main pc gpu, it doesn t display through mbo. Any ideeas? Thanks in advance for answers <3
