Pixelated lines on 2408wfp

Question

Hi, I'm experiencing pixelated lines as shown in the figure, on my 2408wfp monitor which I haven't used that much. Last week it started and it looks like the more I use it since then, the more bands apear. I was wondering if this is caused by a bad display or rather another electronic component. I have fixed displays before, so I'm considering doing the same thing (it's no longer under warranty) but it would be nice to get some pointers such as: is it fixable or not and which components might be causing these symptoms? Thanks in advance, Best Regards, Tim

Hi Tim,

I will recommend you to run a Self-Test feauture on the monitor:

Turn off both your computer and the monitor.
Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital (white connector) and the Analog (blue connector) cables from the back of computer.
Turn on the monitor.
The floating dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green.

Keep me posted. Please reply for any further questions.

Hi Tim,

You could try changing the power cable and see if that makes a difference. In case the issue still persists, you may consider replacing the monitor as Dell does not have a monitor repair team.
