I have a 30" Dell 3007 wfp which runs natively at (2560x1600) as my primary display (Win7/64). Video card is HIS Radeon 6970 ICEQ Turbo (2GB), which has two video display ports, HDMI, DVI-single-link, DVI-dual-link.
The 3007 native resolution displays properly when it is the only monitor (yes, needs to be on the dual-link DVI, not single-link DVI).
HOWEVER, every time I try to plug in a second monitor (21" Dell 2007 or Dell 2001, native 1600x1200), my 30" monitor no longer displays at native res, and somehow seems to "max-out" at 1280x800. It doesn't matter if I plug the second monitor into the single-link DVI, the HDMI, or either of the video display ports. It doesn't matter if I plug both monitors into each of the video display ports (not using DVI at all).
The specs on this card seem to say I should be able to get this working: 30" primary, and I'd like one or two more 21" extra monitors. (Don't much care about performance, I'm not gaming, I just want the real estate.)
What is the "proper" configuration for more than one monitor, when one is a 30" 2560x1600?
I assume it is not a driver issue (I'm running the latest, AMD Catalyst 11.12, Driver Packaging Version 8.92-111109a-129966C-ATI).
Aside: I don't think it's a driver problem, but in my search, I pulled an 8MB "driver" for the 3007wfp directly from the Dell website, and my SuperAntiSpyware runtime detected a trojan (weird, cleaned that up, makes me wonder what's going on over at Dell).
