Why is my HP Monitor screen blank or flashing?
- PpaulmedinaAug 12, 2025
If your HP Monitor screen is blank or the video is flashing, it might be due to several reasons. First, ensure the power cord is securely connected. Next, check if the power button on the monitor's front panel is turned on; if pressing it does nothing, try holding it down for 10 seconds to disable the power button lockout feature. Also, verify that the video cable is properly connected, paying attention to the DisplayPort IN connector if you're using a DisplayPort cable. If screen blanking is active, press any key on the keyboard or move the mouse. Finally, for video card compatibility issues, disable Input Auto-Switch Source in the OSD menu and manually select the input.
