I received my new U2713HM less than a week ago. It's revision A00, manufactured in May of 2014. It's a beautiful large screen, and I was very excited to fire it up. It's perfect except for a horrible image retention problem. Leaving ANY light colored static window onscreen for as little as 10 minutes causes that image to temporarily be burnt into the screen and retained as a faint background image when you view something dark (ie. a video).
This monitor is a secondary monitor attached to my 2012 Macbook Pro via mini display port to display port cable. Monitor brightness is set to 53. All other settings are default.
I've never seen this issue with another monitor, and have used many monitors (including other IPS monitors) in single and dual monitor configurations. I just purchased a pair of Dell P2314H monitors for my office that do not have this problem.
Many people are very pleased with this monitor, and equally many seem to have this same problem. I wish I could recommend this monitor but this image retention problem on a brand new, premium monitor is unacceptable.
Dell support has been of zero assistance in this issue. I spent over an hour on the phone, was hung up on twice. The first tech attempted to pass the buck and said it was a software problem with my Macbook Pro, he wanted me to call Apple. Second tech said Dell would send me a replacement and then hung up on me. Last tech told me that I'd need the retailer's order number (the order the retailer placed for the monitor from Dell) in order to get any support from Dell.
Finally I gave up and contacted the retailer. I'll be returning the monitor to them. I later found the link below on this forum which provide procedures, as well as some surprising info (your "three year" warranty begins from the time your retailer receives the product, thus any time the product sits on a store shelf counts against your warranty period?!)
I'm sad to say that Dell's pathetic customer service in this case has likely cost them a customer. I guess I'll be replacing this monitor with another brand. If this had unfolded before I purchased monitors for my office I wouldn't have bought the P2314h's either.
If you do decide to purchase a Dell monitor be sure to buy a SquareTrade warranty!
