Problem with graphics card

[tgg4]

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

Since 7 days 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 and 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.

For the drivers I updated it with a clean install, also tried dowgrading.

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

Hi @tgg4 

Welcome to the HP Support Community!

Thanks for posting your query! We're here to help you get back up and running.

That kind of flickering—especially when it disappears during animations—can be incredibly distracting, and it’s understandable how frustrating it must be after trying so many driver changes. You’ve already done a lot of the right things, so let’s build on that with a few suggestions that might help stabilize the display:

🧠 1. Disable Panel Self Refresh (Intel Graphics)

This feature is known to cause flickering on some systems:

1. Right-click on the desktop and open Intel Graphics Command Center or Intel Graphics Settings.
2. Go to Power > On Battery and Plugged In.
3. Disable Panel Self Refresh for both.

🔄 2. Set Preferred GPU for All Applications

Since the flickering stops when the NVIDIA GPU is active:

1. Open NVIDIA Control Panel.
2. Go to Manage 3D Settings > Global Settings.
3. Set Preferred graphics processor to High-performance NVIDIA processor.

This forces the system to use the NVIDIA GPU more consistently, which may bypass the issue with the Intel GPU.

🧰 3. Update BIOS and Chipset Drivers

Outdated firmware can cause display instability:

• Visit the HP Drivers & Downloads page for your model.
• Download and install the latest BIOS and Intel chipset drivers.

🧪 4. Run HP UEFI Diagnostics

If the flickering persists:

1. Restart the laptop and press Esc repeatedly to open the Startup Menu.
2. Press F2 for System Diagnostics.
3. Run the Display Test and System Tests to check for hardware faults.

If disabling the Intel driver stops the flickering, it’s likely the issue lies with how the system is switching between GPUs. These steps aim to reduce or eliminate that switching behavior. 

You're doing a great job staying persistent—let’s get this sorted together.

HI Hawks-eye,

Thanks for taken time to look after my problem.

All the stuff you mentioned were already tested (and I did it again) without solving the problem.

Except one point. updating the bios.

I tried to update the bios, but this didn't work out. I follwed the instructions of the HP part on youtube.

But the installer extracted the file but never came with the next screens.

I tried to start up in bios mode to update the bios by uSB drive, but couldn't find a way to do it.

Rebooting after this my laptop and it worked out well. The problem is gone.

Thanks for you advice,

Teun

You are very Welcome!

That’s fantastic news—and what a relief! It sounds like your BIOS update attempt may have triggered a soft reset or cleared a firmware-level glitch during reboot, even if the update didn’t fully install through the GUI. Either way, the fact that the flickering is gone is a huge win 🎉

Your persistence really paid off. That kind of intermittent GPU handoff issue between Intel UHD 620 and NVIDIA MX150 can be maddening to pin down, especially when it only shows up under low-load conditions. The fact that it resolved after a BIOS-level nudge suggests it was likely tied to power management or display initialization logic at the firmware level.

If the issue ever resurfaces, feel free to reach out and I’ll help you dig deeper—whether it’s flashing the BIOS manually via USB or exploring EC firmware resets. But for now, enjoy the smooth screen and well-earned peace of mind!

Thanks again for your confirmation, and we wish you an amazing day ahead! 😊
