flickering 2nd display

[umfi]

When working with the second display it occasionally switches off or distorts when working with VMWare. This happens only on the second display. I have updated AMD drivers. Problem with 75Hz monitor and 60.

This happens for some reason, but when working with VMWare on the second screen, or with Visual Studio. Every now and then the screen switches off for a few seconds. And when working with VMWare, artefacts appear.

Same as this post https://h30434.www3.hp.com/t5/Notebook-Video-Display-and-Touch/OMEN-by-HP-Laptop-16-c0xxx-flickering...

Hi @umfi,

Welcome to the HP Support Community

I understand you are facing a flickering 2nd display with your OMEN 16.1 Inch Gaming Laptop PC 16-C0000. Not to worry I will help you to get a resolution to resolve the issue.

May I know if you have checked to connect  another monitor and still display flickering 

Please try the following Troubleshoots steps.

1.    Turn off the Unit.

2.    Disconnect the AC adapter.

3.    Remove any discs from the disc drive.

4.    Remove memory cards from the card reader slot.

5.    Disconnect all nonessential peripheral devices, such as printers, scanners, external hard drives, and USB flash drives.

6.    Disconnect the AC adapter press and hold the power button for approximately 15 seconds.

7.    Reconnect the AC adapter, and then turn on the computer.

Step 2

Turn off the unit and please press and hold the Windows key + letter B key and the power button together for 30 seconds after 30 seconds, 1st release the power button but keep holding the Windows key and B key for ten more seconds and then release these two keys If done correctly, you will see the display flashing once. Please attempt it thrice as this step and Restart the unit

Step3

The unit has to be turned off, Press Win+ V while holding these two keys then Press the Power button, continue to hold all three keys for 30 seconds and then release the Power button first and then release these two keys Please attempt it thrice  and then you may get a Pop-Up CMOS Check and it will restart the unit 

Even if you don't get a Pop-up restart the unit manually after 3 attempts.

Try performing a BIOS default on your PC and check if it helps. and check if the screen is flickering in BIOS as well  

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 to 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 using the HP support assistant.,

Is this the first time you are connecting your monitors to your Omen laptop?

Or did it work normally before?

Sometimes due to a loose cable connection, this issue will occur.

Please  update Windows and HP support assistances updates

I have updated the BIOS and have yet to see the second screen flicker

[umfi]

The point is that the second monitor connected via hdmi I just switch off for a second. The same happens with the second monitor connected via hdmi. After updating the bios it became less frequent

[umfi]

My monitor randomly switches off for a second. no matter what action is going on, it just might switch off. Tried different hdmi cables, different monitors. It still happens the same way
