after booting, screen pulsates when the color grey is displayed

[abi_29]

once i start my device after putting it on sleep, the display starts blinking only when the color grey(RGB value 53,54,58) is shown. i also cannot seem to replicate this issue by forcing it to sleep(closing the lid), booting the laptop, and even using the power options to put it to sleep on the windows start bar. The video below somewhat captures what im talking about. ive also updated my graphic drivers but the issue still persists.

Hi@abi_29, Welcome to the HP Support Community!

I understand when you power on your laptop the screen keeps flickering on your laptop.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

Does the issue persist in BIOS?

As you mentioned when you power on your laptop the screen keeps flickering on your laptop.

If the issue does not persist in BIOS try updating the graphics driver and BIOS on your PC.

Try performing a BIOS default on your PC and check if it helps.

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer.

Also, Uninstall the graphics driver from the device manager and install the latest drivers and BIOS from the links below.

Also, update the graphics driver using this link.

You can try updating the drivers on your PC using an HP support assistant.

If the screen is flickering in BIOS, it is certainly a hardware issue with your PC.

Hope this helps! Keep me posted.

ill try updating my bios, i updated and reinstalled the graphic drivers but they dont seem to fix it. and i doubt this problem would persist in the BIOS since this flickering can only bee seen on slightly darker colors (not black, more of grey tones)
