I have a U3011 and an NVIDIA GTX 680, before this card I had a GTX 570. With either card and using DP I have a black screen during bootup untill windows comes up and from then on everything is fine. With DVI I can see the whole boot process (BIOS stuff, hard drives, memory, etc...) Any ideas? If...
My FHD2400 does this same thing, all the other inputs are affected after using HDMI and then switching to any of the other inputs. I have to unplug the A/C power plug on the monitor to reset it. Did you get yours replaced, or call customer service?
Thanks,
Tom
