I've had my U2311H for about half a year now and it has been working really well. Today, a bunch of gray lines suddenly appeared on the bottom half of the screen. The entire screen is a lot dimmer than it was originally, and color became less saturated. The gray lines on the bottom half has a lot of ghosting effects, and everything becomes really hard to read.
I tried factory reset, restarting the monitor. This did not help.
I have the latest drivers for my graphics card, and my second monitor displays perfectly.
I tested with my extra DVI cable and the problem persists.
Does anyone know what might be causing this andhow to fix it?
Here's some pictures I took of this with my phone:
Run the Self-Test and Built-in Diagnostics. If they fail and the warranty is still valid, if you only have a monitor order number, you should contact Order Support. If your monitor was purchased tied to a Dell PC, contact Technical Support. They will need the following data -Email Address:Name:Shipping Address:Phone Number:Monitor Order number or attached PC Service Tag number:Monitor 20 digit PPID number:Reason:http://dl.dropbox.com/u/3085200/monitor/IMAG0148.jpghttp://dl.dropbox.com/u/3085200/monitor/IMAG0149.jpg
