I just added a second Dell U3011 to my rig. Both set to Native Resolution (2560 x 1600). But one display is visibly poor. I switched the DVI-D cables and it switches to other screen. I use a third DVI-D cable but problem persists. I've Googled but find nothing that might explain it.

I'm beginning to suspect one of my two GTX 670's is defective??

The only way I could present it to you is take a photograph of screen. If I Snip a pic from bad screen and display on good screen it looks fine!

My Rig:
Intel Core i7 Processor 4770k @3.5GHz
ASUS MAXIMUS VI FORMULA LGA 1150 Intel Z87 HDMI SA
G.SKILL Trident X Series 16GB 2133 CAS Timing 9-11-11-31
Cooler Master Seidon 120V – Sealed water cooler
TWO - GIGABYTE GeForce GTX 670 OC 2 GB
Intel 320 Series 160 GB SATA 3.0 Gb-s 2.5-Inch Solid-State Drive - SSDSA2CW160G3K5
Seagate Barracuda XT ST32000641AS 2TB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive
Western Digital Caviar Green WD20EARS 2TB SATA 3.0Gb/s 3.5" Internal Hard Drive
2x Pioneer DVR-219LBK-20 Dvdrw 24x Sata Black
HAF X Case
FOUR Master Cooler Case Fans

Ideas Please!!

It's not a great shot saved and uploaded. You can see the degradation in the Office Word alert question. Picture is degraded to but harder to tell here.
