HP OMEN flashing screen

[Raphaeln]

Hi,

I bought a HP OMEN last month. When I start it, I have some flashes on the screen, about every 10 seconds. It stop after 5 minutes. Some times this doesn't happen at all, but most of the time I have this problem.

Could someone tell me the signification of theses flashes and what I need to do to stop that ?

For information, the screen is an ASUS XG49V.

Thank you in advance.

This is a video of my screen, you could see the flashes at 4 and 16 seconds.

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to assist you.

I see that you are facing an issue with your Laptop screen flickering.

Follow the below steps to access the BIOS menu.

1) Hold the power button for at least five seconds to turn off the computer. (Wait for a few seconds after releasing the power button)

2) Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu is displayed, press the f10 to access the BIOS menu.

If the issue appears on the BIOS, there is an issue with the hardware.

Kindly refer to the steps on this link to update the BIOS and let me know if that fixes the issue.

Hi,

Thanks for your reply. The second problem is solved with a BIOS resintall.

Then I have started the computer and stay in the BIOS for about 10 minutes, no flickering.
restart and go to windows : flickering again for 3 or 5 minutes.

Any idea ? 🙂

Kind regards,

As the screen does not flicker in BIOS, the hardware is working fine.

Hi,

I did a Recovery as mentionned. After reinstall only the software, without any other connection etc, the flickering is... here again.

No flickering during reinstall.

On the other hand I noticed that when I plug a USB socket (an external HD for example) I have one or 2 flickering .

Kind regards
