I have reset BIOS and restarted several time, waiting 5 mins after shutting down.  When monitor comes on the top half of screen remains darker than bottom.

Remember: Do not share any of your personal information such as serial, phone number, email ID, etc.


Also, in the mean time, I wanted to know if there's any way you can connect an external monitor to your device and check if that display works fine,

If it works fine, the display on the all-in-one, may need a replacement, however, if that doesn't work either, we may need to work on reinstalling the drivers for your graphics card, among other things to resolve the issue.


P.S: Welcome to HP Community 😉

Keep me posted, and if any of the above questionnaires helped resolve the issue, 

Mark this post as an "Accepted Solution".

Good luck.
