Hi there,

I've got an old U2414H that upon coming back from sleep, shows black on the right side of the screen, as pictured:

I've confirmed this issue on other computers, with other cables, both DisplayPort and HDMI. Even with no display cable connected at all I've noticed the issue on the built-in Dell menu. I've reset to factory settings and run the self-test, which shows no issue.

If I power cycle or display input cycle between 2-12 times, the issue goes away and the U2414H works fine. This seems to only happen after coming back from sleep, or after powering the U2414H on for the first time of the day.

I understand this was manufactured on in 2014 so it's out of warranty. The U2414H works great besides this issue. Is there any chance for a solution, or anyone out there that has managed to fix this?

Thank you for your help!
