Hello,
I was looking for a similar answer for the issue I have with my monitor Dell U3011. I have 3 long lines (looks like hair) of dead pixels about 1/2" long and several(7 or 8 at least) small dead pixel dots, I'm using Mac's app Screen Utility to run test and those dead pixels can be seen under red, green, blue and white background. I am using Macbook Pro Retina 15 and this U3011 for Graphic work and those dead pixels really become bothersome. The service tag says the warranty expires in 11/2015. I can provide you with the service tag upon request
How do I go about getting a replacement?
Thank you for your help!
