Hello, I just built a new PC and purchased a GTX 970. For some reason, I get no display via HDMI, I've tried 3 different cables (verified that they are working with other devices) but both DVI ports work fine. I've reseated the card multiple times. Is there anything else I can try or does it seem like the card has a bad HDMI port? The only thing of note that I can think of is that my power supply is older (but never used until now) and only has 6 pins, I have a 6 to 6+2 adapter on the way from Amazon right now. The LED lights up fine and games run at max settings wonderfully with the way it is right now, so I can't believe the HDMI issue would be due to that.
