Hi all. I bought my Dell U2713HM three months ago, and I've been very satisfied with it so far. However, this morning, when I started my pc and my monitor, it displayed very weird vertical lines and I could barely see what was on the screen (or rather what *should* be on the screen). Here is a video explaining the problem: http://youtu.be/FEGJh609NPQ
And here's a video while performing the monitor self-test: http://youtu.be/FLFdUxCyPNc
As you can see, no other devices were connected to the monitor. To be sure I tested it with my desktop (DVI) and with my raspberry pi (HDMI). The problem was exactly the same.
I hope you can help me, this monitor wasn't cheap :/
