Did you have the DVI and HDMI cable connected to the same display at the same time? If so, disconnect one of them and try again.
I connected my vga monitor with my dvi monitor on the board and they both worked perfectly. It's when I disconnected my vga and plugged in my hdmi it didn't work. The board doesn't seem to recognise hdmi. AllI want to do is download movies on my desktop and watch on my wide screen.
