Welcome to the HP Support Community!
I reviewed your post and I understand you are facing issues with the display on your computer.
Don’t worry, I assure you I will try my best to get this sorted.
What is the exact model for your computer?
Meanwhile, I recommend you update the BIOS and the graphics driver from the below link and check if it helps.
If you continue facing the issue, I recommend you boot to BIOS by tapping the F10 key on startup and check whether you are able to duplicate the issue on the BIOS screen.
Let me know how it goes and you have a great day!
