Im having problems gettin my Msi twin frozr r9 290 to work, I tried running power to it with one cable from psu as well as 2 separate cables, reseated it a few times and nothing im wondering if it could be from using hdmi cable instead of dvi?Maybe I need drivers before using hdmi, I dont have dvi d cables in hand right now but thats my next and last thing to try.
Asus maximus vi mobo

Intel i5 4670k
Os windows 8.1
beezy might be right, hdmi is a digital input while the others are analog, so you may need to find a vga cable to use the card without drivers. I know within CCC there is a HDMI driver in the software.
there was another guy who bought a VGA adapter just to try this and it didn't work for him so I really hope it fixes it, since youll have to make an additional purchase for it. if you can take your tower and test it w a buddys monitor with his VGA cable that would be best, then you get the drivers and just go hdmi after that.
