I recently got the 970 Pro Gaming Motherboard. I'm very new to PC building but I followed the manual to the best I can and managed to get the power going and the LEDs on but the monitor says"no signal". The motherboard doesn't have an outlet to a VGA cable. My GPU is the GTX 1050 ti, I have the HDMI cable hooked up but does my monitor need the DVI cable from the GPU?
