HDMI video output on ASRock H77M mobo?

Postby gubmint on Sat Dec 07, 2013 7:10 pm

I have an ASRock H77M motherboard and am using the onboard graphics card. I can't get HDMI video output to work, but DVI/VGA are okay. No connection is seen with HDMI. I'm running Mint 14 64-bit.

I found in one of the Newegg reviews, "The onboard video did not work via HDMI on a fresh install of Windows 8 until I updated the drivers. I'm not calling this a con, but it definitely was an unpleasant surprise. I was first worried that the board was bad. Plugging in a VGA cable made it work just fine, so I was able to install Win8 and had no problems after that, it just caught me off guard." So, I figured updating drivers is in order. Unfortunately, ASRock only provides Windows drivers for it...

I've read in several threads here and elsewhere, such as http://forums.linuxmint.com/viewtopic.php?f=47&t=133015, that ASRock doesn't support Linux at all, but some of their packaged stuff suggests otherwise (example: http://www.asrock.com/nettop/download.asp?Model=ION%20330HT&o=Linux), so maybe it's just a labeling issue? On the other hand, many people say to not bother with mobo drivers, as Linux has all those needs built in. But, I did find a few things like this:

http://www.minecraftforum.net/topic/802 ... or-ubuntu/

"Most desktop hardware, unless it's unusual or specialized in some way, will work fine without additional drivers (video cards being the notable exception)"

My bios version is 1.20 and the current version is 1.60, so maybe I should try an Instant Flash update? That doesn't look to be OS-specific.

I also tried booting to Live CD for a fresh Mint 16 download, to see if that would have newer drivers for the motherboard, but it still doesn't see the HDMI connection.

Linux Mint is funded by ads and donations.

Never mind, it was a cabling issue.
