Nixeus Vue 30 blank with resolution 2560 x 1600, 1920 x 1200, etc.

Hey Guys (& Gals),

I have three monitors connected to a Sapphire HD 7790. 1) Dell 3007WFP-HC, 2) Nixeus 30" VUE & 3) Dell U2412M.
The U2412M is connected via Display Port, the 3007WFP & VUE 30" DVI.
Would like the resolution on all three to be 1920 x 1200 but when I set that on the Nixeus all I get is a blank screen. Right now the Nixeus is 1920 x 1080 & the other two are 1920 x 1200. I find the Nixeus doesn't like other settings as well e.g. 2560x1600 & 1600x1200. It will appear blank on both of those as well. Am I missing something?

I used the AMD Catalyst Un-install Utility & then Driver Sweeper to clean out old driver files. Used the AMD Driver Autodetect & updated to the most current.
If I connect the Nixeus via Display Port (1.2) I can get it to run 1920 x 1200 simultaneously with the two Dell monitors but would rather have it on DVI, should I want to set the resolution at 2560 x 1600.

thanks

Start with double checking that you have the Nixeus connected to the one dual link DVI port on the card (the black one), and that you are using a dual link DVI cable.

Well I was wondering why one of them was black? But according to the specs both the DVI-I & DVI-D ports are Dual Link. Yes both DVI cables are Dual Link.

I switched the Nixeus back to the displayport. The other two are connected via DVI at this point & all three are running at 1920x1200. Seems to be an issue when Nixeus is on DVI. I will switch it to the other DVI port & see what happens.

I'm sorry for being a Gumby - operator error. You were spot on.

Have three Dual Link DVI cables & one Single Link DVI cable, somehow got that one into the mix.

Replaced the single link with a dual link & now everything is working.
