Monitor starts flickering

HP Recommended
HP Pavilion Gaming Laptop 15-cx0xxx
Ubuntu LTS

Hi,

from time to time, I have problems with my external monitor, connected via USB-c to HDMI. Suddenly the display is black, starts flickering or something else so I have to deactivate it. The problem already exists a few years, but with better times and worse times. The last week is terrible, in nearly every session, the error occurs.

Could this problem be my cable? I already tried an adapter and a direct cable. I use Ubuntu and Win10, the error occurs in both OS. Interestingly, most of the time, it starts when I start a new application.

Does anyone have the same problem or an idea?

@, 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 device manager and install the latest drivers and BIOS from the links below.

 

Link to update the BIOS.

 

Also, update the graphics driver using this link.

 

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

 

Refer this article to know more information about using HP support assistant.

 

Refer this article to further troubleshoot display issues with your PC.

 

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

 

Please contact HP support for service options.

Hope this helps! Keep me posted.
