"Small" screens in 3-monitor mode on Gigabyte 7970.

post #1 of 3
Thread Starter 
I have three LG 23" IPS displays and an almost new Gigabyte 7970 with 1xDVI, 1xHDMI and 2xMini-DP.

I bought two Active mini-DP adapters and three 1.3a HDMI cables to actually hook my monitors up with since they're all 1080p screens they should be all I need.

Whichever two screens I hook up to the mini-DP adapters work perfectly, but if I hook a monitor up to either the DVI (with a DVI-HDMI adapter) or HDMI port (I've tried each monitor on all ports) the screen will be detected at 1080p, configure properly, but then display the image with about 3/4" of dead space around the image on the monitor.

I'm currently running the screens on 1xDVI to DVI cable and two mini-DP to HMDI's and it works correctly, but that means I can't hook up my projector which requires VGA.

So my question is simply, why the heck can't I run three HDMI cables to my three monitors correctly? Anybody have experience with this issue?

It seems like the monitor isn't configured properly. Make sure the monitor isn't at letter box mode and it is actually full screen and at 16:9. I had a monitor than when it was connected to my PC it would read it as 16:10 not 16:9.
