Bottom 3/4 of screen is normal but it duplicates itself on the top 1/4

[Deb552]

My screen suddenly splits and duplicates itself... I have normal page open on display on bottom 3/4 but it also repeats itself and shows duplicate of screen again on top 1/4. I have rebooted twice but still persists

@Deb552 Here's what you need to do, to identify the issue and resolve it accordingly:

• If not done already, check if it works fine on the BIOS screen to identify if it's either a hardware or a software issue:
  • If it works fine on the BIOS (Accessed while tapping F10 during a restart) it's a software issue & I suggest creating a new user account to check if that works better, for starters)
  • However, if it doesn't work within the BIOS either, I'm afraid it's a hardware malfunction.

While you respond to that, I have a few more steps that should help:

Attempt to run a test from the HP hardware diagnostic tool, using this link: Click here for details.

If the display isn't appearing normal on the diagnostics, it could again, determine a hardware failure,

If it works on bios & the hardware tests passed: please update the BIOS, Chipset & Graphics card drivers from the HP website using this link: Click here

if the issue persists, reinstall windows using the recovery partition or the recovery media to fix the issue,
use this link for details on performing the recovery: Click here
