Problem with Intel UHD 620--> flickering screen when no animated graphics

[TGG1]

My HPx360 laptop has an Intel UHD 620 onboard graphics card and a Nvidia GeForce MX150 graphics card.

Since two day my screen on my laptop is flickering (black screens).

I noticed that when I open a motion grapics program or website with animation the flickering stops.

For example when I open the NVIDIA configuration program en there I open the page with the 3D animation the flickering stops.

I tried to install the latest drivers and went back to earlier drivers. 

What could be the problem,

Disabeling the graphics driver for the Intel card also solve the problem, but that is not the real solution, because some functions are lost.

I search several forums, but couldn't find this particular issue.

Hi @TGG1,

Thank you for posting here in our community. To effectively diagnose and address the issue you're experiencing, I kindly ask you to provide detailed responses to the following questions. This information will help us isolate the problem and determine the most appropriate course of action.  

• Please provide the SSU log report and share it here so I can review your system's configuration. 
• Have you previously performed a clean installation of the graphics driver, before using either an older or the latest version? 
• Have there been any recent updates or changes to your system, such as Windows updates, software installations, or hardware modifications?
• Can you specify the versions of the Intel UHD 620 and Nvidia GeForce MX150 drivers you have tried? Did you use the manufacturer's website or a third-party source for these drivers?
• Are you using any external monitors or display adapters? If so, does the flickering occur on external displays as well?
• Have you adjusted any power settings recently, such as switching between power-saving and performance modes? Does the flickering change when the laptop is plugged in versus running on battery?
• Have you checked the Windows Event Viewer for any error messages or warnings related to the graphics cards or display?
• Have you considered performing a system restore to a point before the flickering started? If so, did it have any effect?

Please note that this is an OEM device, so we will try to assist you with general troubleshooting steps. However, if the issue persists, you will have to contact the Original Equipment Manufacturer of your device. Your device manufacturer may have altered features, incorporated customizations, or made other changes to some components for better compatibility with your system.

I look forward to your response and am committed to resolving your issue promptly.

Hi Randy,

Thanks for your info.

I have attached the SSU log.

I didn’t update the drivers before the problem appeared.

I was running (for some years) without problem intel version 31.0.101.2121

After the problem appeared I upgraded to 31.0.101.2135. I did a clean install.

No solved. I downgraded again to version 2121 (clean install) and upgraded again.

I upgraded my NVIDIA driver from 556.12 to 576.80. (did also a downgrade, but no solution)

All the drivers I used where no third party drivers, but direct from Intel or Nvidia.

At the place where I am now I don’t have the possibility to try an external monitor.

The flickering appears  when using a battery and also using the power supply.

In the windows event viewer there are no error messages which I can relate to the graphics cards.

There are no hardware changes the laptop is still original.

When the first time the problem appeared there was one windows update installed:

2025-05: Cumulative update for Windows 11 version 24h2 (KB5058411).

I have un installed the update, but the problem was there still.

This is all the information I can provide for the moment.

Thanks for looking after this problem.

Greetings, Teun

Hi @TGG1,

Since the issue started after a Windows update, consider rolling back to a previous stable version of Windows if possible, or check for any pending updates that might address the issue. I checked the SSU report and noticed that your system BIOS is outdated (last updated on 10-30-2017).Check if there is a BIOS update available for the laptop, as this can sometimes resolve compatibility issues with drivers and hardware. You may also boot the laptop in Safe Mode to see if the flickering persists, which can help determine if the issue is software-related.

If feasible, perform a system restore to a point before the issue began, ensuring all important data is backed up first. If the issue remains unresolved, consider contacting HP support for further assistance, as they may have more specific solutions or patches for this issue.
