Second display connected to motherBoard not working

Post by neosmith » Tue Mar 13, 2018 6:56 pm

Hello everyone,

Info: Linux Mint 18.2 Sonya. BenQ 27" connected to HDMI port at GTX 660, and LG M2252 to motherboard Gigabyte Z77X-D3H.

I've bought a new Display, a BenQ 27", and connect it to the HDMI on my graphic card. Because I don't have another HDMI connector into it, I connected my previous screen (LG M2252) to the HDMI port at the motherboard. I changed BIOS settings in order to get the motherboard enabled, and It seems it detect it. The point is, I can select sound to get throug the LG screen, but the only thing I'm seeing in it, are the dots of Linux Mint. I can not see it into "Display", I just see BenQ.

Interesting thing is, I can make sound go to the LG:

Sound screen, outputs, selected is HDMI with screen apparently not wanting to work.
Anyone got an idea of what could I try? On windows, it's working by the way. And the point is, it previously worked, but connected to the HDMI port, not to the motherboard. But I can see the 5 dots of Linux Mint ! :?


Lot's of thanks !!!
