Yes.

Where will I find those?

I have not done any testing specific to this issue. It occurs occasionally during normal use.

I have raised a case with Dell Support and have been asked to take pics next time the issue occurs and to mail those to the techie.

I am now using a new GPU, so perhaps that may eliminate the problem.

What specific Nvidia video card model? (GTX 770 etc)
Are you saying that the Nvidia video card only has the one DVI-D port?
Look for a label on the rear of the monitor for those numbers.

My U2913WM occasionally shows a green tinge which disappears when I power off and on again. This has happened with two different GPUs. Unfortunately it is completely random and I cannot recreate the situation. What is my best course of action?

Hi Hairy Scot,

Thanks for posting.

Please be sure you are using the correct cable.  DVI Dual Link cable. Part no. X056C.

Hi Robert P,

I am using the DVI cable that was supplied with the monitor.

Have you tried the monitor on another system?  Do you have the same results?  If so, perhaps contacting Tech Support and troubleshooting with them may be in order.
