no it did not help the situation.
The solution to your problem is quite simple. The DP port in your NUC has DP 1.2 type output while your monitor input is set by default to DP 1.1. In order to avoid display blinking enable DP 1.2 in your monitor DISPLAY settings menu. See the attached image.

Yes, that seems to be the issue. Thank you!
Turn the computer off.
Press and hold the D key while pressing the power button. This will start the Laptop LCD BIST.
The screen will display multiple flashing colors. Look for lines, distortion, or any other video issues you have observed.
The laptop will restart when the test is finished.
For more fixes refer to Dell U2515hDell Manual.
