Resolve Windows 10 related issues for your HP computers or printers by HP Windows 10 Support Center
Welcome to HP Forums,
This is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂
If you haven't, Please try an alternate monitor to understand if this is either a hardware or a software failure,
if the issue does not appear on the alternate monitor, you may need to replace the display assembly on your computer,
if the issue appears on the alternate monitor/TV as well, re-install the graphics card drivers & update it from the official HP Website: Click here
If you don’t have an alternate monitor, I recommend checking if the issue appears on the BIOS screen (restart the computer and tap on F10 to access BIOS)
If the issue does not appear in BIOS, reinstall the graphics card drivers & update BIOS using the above link.
Let me know how that pans out,
I hope you have a good day ahead,
And Feel free to ask any other queries as well,
Considering, this forum has some of the best people in the world available and ready to help. 🙂
