Reinstall the integrated graphics driver

The steps below take about 15-20 minutes to execute. Please follow each step, 1 by 1, without skipping them, including the reboots of the machine.

2.1.1: Identify your PC by following the instructions in this video to get your SERIAL NUMBER:

• External Link: Find your HP computer product & serial number | HP Support

You should get something like this:

2.1.2: Go to the HP Website and select your laptop model. You can find the exact model by inputing the Serial number above:

• External Link: HP Drivers

2.1.3: Enter the laptop name in this box:

2.1.4: Select the Windows name and make sure to select version 22H2 from the list. The drivers for 23H2 and 24H2 versions will fail!

• External Link: Windows 11 release information - Servicing channels

2.1.5: Select the Drivers-Graphics and 'Download' version 31.0.101.4034 Rev.A

If this version fails you may also try version 31.0.101.4502 Rev.A

When prompted to use the HP Assistant, please select 'Manual install' instead:

2.1.6: Download and install 7-Zip:

• External Link: 7-Zip

2.1.7: Extract the driver you downloaded with 7-zip by right-clicking -> 7-ZIP -> Extract here:

2.1.8: The extracted driver will look different depending on the Windows version you selected.

2.1.9: Then, right-click the Start button -> Device Manager:

2.1.10: Expand Display adapters -> Select your Intel UHD (or Iris XE) graphics card -> right-click -> Uninstall device.

2.1.11: Disconnect from the internet.

2.1.12: Reboot the machine. 

2.1.13: Open again the Device Manager (step 9.) -> Display adapters -> Select the Intel device (note: it may appear as unknown device since the driver is not installed)

2.1.14: Right-click the Intel device -> Update driver:

2.1.15: Select 'Browse my computer for drivers' and select the .EXE file you extracted in step 7.

Important: do not select the .EXE that you downloaded in step 5., but the extracted version after you used 7-Zip:

Ensure that, when browsing for the driver and if you extracted in a subfolder, the subfolder named dhCU_graphics or similar is selected. Windows will pick up the driver automatically:

2.1.16: Finish the installation by clicking 'Ok' or 'Next' until the setup is done.

2.1.17: Reboot your machine and try Lumion again.
