Thank you for posting on the HP Support Community.
Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:
-
Turn off the computer.
-
Disconnect all connected devices from the computer except the mouse, and keyboard. This includes removing web cameras, USB devices, thumb drives, camera-type memory cards, and other displays.
-
If the display has a detachable cable, obtain a second display cable for testing purposes.
-
Disconnect the display power cable, wait about 30 seconds, reconnect the cable and then turn on the display. This resets the electronics on the display.
Use the following steps to see if a built-in on-screen message is displayed.
-
Connect the video cable and turn on the computer.
-
Turn on the display and wait about ten seconds while the computer starts.
-
While the computer is starting, disconnect the video cable. What happens?
Hope this helps! Keep me posted for further assistance.
