I have this problem too. My old monitor P2414H works on the same computer without this "vertical lines" problem. But with this U2419H each time the movement is on the screen (for example, moving a window in Windows 10), these lines appear. I tried it also on different computer with the same bad result. So far I have only had good experience with Dell monitors. But now ... 😞
We will need more data before we can troubleshoot.

Thank you for your response. However, I don't need your help anymore. The problem with vertical lines disappeared after two days of using the monitor. Probably needed to properly warm up. The monitor seems to be working as it should now. Have a nice day! mrimmer26
