I have the GA-J1800N-D2P (rev. 1.0) board and have had it working flawlessly since I bought it just over a year ago. I've always used VGA but recently decided to use HDMI. Can I get any output? No.
I've tried everything I can think of. I've tried two modern TVs and three HDMI cables. I'm running Windows 10 64 bit and have tried it with and without the official drivers. Still nothing.
I should add that my laptop works with all the combinations of TV and HDMI cable, so I know that part of the chain is good.
What am I missing??
