6. Change brightness settings

1. In the Power Options, find your current power plan and click Edit plan settings.
2. Up next, click the Change advanced power settings option.
3. Locate the Display brightness setting and make sure that you set the display brightness to 99% or 98% when your device is plugged in.
4. Save changes and restart your computer.

Another reason for the flashing black box on the screen could be the wrong brightness settings. Setting display brightness to 100% when your device is plugged in causes this problem, so it’s best that you use a lower value.
