Gigabyte AMD Radeon 7750 - 3 displays?

post #1 of 5
Thread Starter 
I currently have a Gigabyte AMD Radeon 7750 video card, It has 2 DVI, 1 VGA, and 1 HDMI connection. I am currently running 2 monitors on the DVI connections. Is it possible to run a 3rd monitor using the VGA connection? I googled it, and some people said you can't... Others said you can. I tried going into the settings... The AMD Catalyst doesn't detect my 3rd monitor... The Windows display properties DOES detect it, but will not allow me to enable it.

What am I doing wrong? Or does this card just not support anything beyond 2 screens?

It is possible to run 3 screens. Anyway, check that video I linked. I assume it will just say to use the HDMI port for the 3rd screen, or by using some sort of splitter.

You need to be using at least one displayport when you'r using more than two monitors on AMD. Reference design 7700 cards should have two mini displayports. LINK

You'r card isn't reference from what you described, so I think you'r limited to two monitors by design of that card. Check to make sure that HDMI port isn't actually a displayport as they do look similar.

His uses a Display-port. I'm pretty sure mine just has HDMI.

It even says "HDMI" beside the port.

I guess it's time to upgrade my card. Damn!

Okay, since you have no displayport output you will need a different card. Makes me wonder why these companies even bother tampering with things like this, it hurts the consumer.
