27in AIO R078a - Half Screen ghosting issue.

[CR84]

Hi All,

I have a HP 27in - R078A (Product code 2NL16AA) All in one and I seem to be having an issue with the left half of the screen. Every 3-10 minutes I am encountering a coloured ghosting / vertical line pattern and sever reduction in  screen quality. It is only happening on the left hand side of the display (pretty much exactly 50% of the screen) Images attached below.

This phenomenon last anywhere from 15 seconds to 2 minutes and does not appear to impact the operation of the computer, other than the display.

I am running the computer duel boot (Win10 Home and Ubuntu 18LTS), although this was occurring well before the duel boot was installed.  I have run every software, OS and graphics driver update I can find and nothing seems to be able to fix the issue.

Any suggestions / ideas in regards to this issue?

@CR84 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
