This article breaks down the process into manageable steps, ensuring that even users with limited technical experience can follow along. We’ll guide you through installing both your integrated Intel HD Graphics 620 driver and your dedicated nVidia GeForce MX110 driver, ensuring both operate correctly on your Windows 8.1 64-bit system.
Step-by-Step Guide to Installing Graphics Drivers on Windows 8.1
Here’s a detailed walkthrough to get your graphics drivers installed and your display working perfectly:
1. Essential Windows Updates
Before attempting to install any graphics drivers, it’s crucial to ensure your Windows 8.1 system is up to date. These updates often include essential security patches and system files that are necessary for driver compatibility.
- Navigate to Device Manager and find Windows Update Center.
- Run Windows Update and install all available updates. This process can be lengthy, potentially taking around 12 hours and involving a download of approximately 5GB (as of 2020). Be patient and ensure your laptop is connected to a power source throughout the process.

The update process is typically completed in two stages, requiring a restart after the first stage before proceeding with the second. After all updates are installed, restart your computer.
2. Installing nVidia GeForce MX110 Drivers
With your system updated, the next step is to install the driver for your dedicated nVidia GeForce MX110 graphics card. It’s important to use the specific driver version mentioned here, as other versions may not be compatible with Windows 8.1 on this HP laptop model based on testing in 2020.
- Download the driver version 441.66-notebook-win8-win7-64bit-international-whql. You can find this driver on websites like DriversCloud or Softpedia. Alternatively, search Google for the exact driver name to find download sources.
- Run the downloaded setup file and follow the on-screen instructions to install the nVidia drivers.
- Once the installation is complete, restart your laptop.
3. (Emergency Step) Identifying nVidia Hardware IDs
In most cases, step 2 should successfully install your nVidia drivers. However, if you encounter issues, this emergency step can help you manually identify your graphics card and potentially find alternative driver solutions.
- Go to Device Manager > Display Adapters. If your nVidia card is listed, right-click on it, select Properties > Details > Hardware Ids.
- Copy the top value, which will be in the format “PCIVEN…”. This is your hardware ID.
Hint: If the dedicated video card isn’t listed under “Display adapters” but appears under “Other devices” as an “Unsupported 3D controller,” follow the same steps by right-clicking on the “Unsupported 3D controller” to find the Hardware IDs.
You can use the Vendor ID (the four characters after “VEN_”, e.g., “10DE” for NVIDIA) to identify the manufacturer using online PCI ID databases like pci-ids.ucw.cz or device search tools like Device Hunt.
For most HP 15-DA0043NQ laptops, this step won’t be necessary, and you can proceed directly to step 4 after successfully completing step 2.
4. Downloading Intel HD Graphics 620 Drivers
Next, we focus on installing the driver for your integrated Intel HD Graphics 620. It’s crucial to download the ZIP archive version of the driver, as the EXE installer may not work due to compatibility issues.
- Download the Intel HD Graphics 620 driver version 154519.4678 or win64_154519.4678 in ZIP format. This specific version can be found on websites like Guru3d.com. Look for the download link for the ZIP archive named “win64_154519.4678.”
It’s worth noting that these specific archived drivers can be difficult to find on official HP or Intel websites, highlighting the need for specific sources like Guru3d.
5. Modifying the Intel Driver INF File
To ensure compatibility, you need to modify the driver’s installation file (.INF file) with your specific hardware ID.
- Extract the downloaded ZIP archive (win64_154519.4678) to a folder.
- Navigate to the extracted folder and locate the file named igdlh64.inf. Open this file with Notepad.
- Identify your Intel Graphics Hardware IDs from Device Manager. Go to Device Manager > Display Adapters. Right-click on your Intel graphics adapter (it might be listed generically before driver installation), select Properties > Details > Hardware Ids. Copy the value that looks like “PCIVEN_8086&DEV_5916&CC_0300”. Note the “DEV_” number, in this example, it is DEV_5916.

- In the igdlh64.inf file, search for your “DEV_” number (e.g., DEV_5916). You’ll find it listed under the “[Windows 10]” section.
- Scroll up to the “[Windows 8.1]” section in the .inf file. Add the following line at the end of the list under the Windows 8.1 section:
%iKBLULTGT2% = iSKLD_w81, PCIVEN_8086&DEV_5916
Note: If your “DEV_” number is different, replace “5916” with your specific DEV number. - Save the modified igdlh64.inf file.
6. Disabling Driver Signature Verification
Windows 8.1 enforces driver signature verification, which can prevent the installation of modified drivers. You need to temporarily disable this feature.
- Press Windows key + C to open the Charms bar. Select Settings > Change PC settings > Update and recovery > Recovery.
- Under “Advanced startup,” click Restart now.
- In the Advanced Startup menu, choose Troubleshoot > Advanced options > Startup Settings > Restart.
- After restart, you’ll see a menu with startup options. Select the option “Disable driver signature enforcement” (usually by pressing the number key associated with it, often 7 or F7). Windows will now start with driver signature enforcement disabled.

7. Installing Intel HD Graphics 620 Driver Manually
Finally, install the modified Intel HD Graphics 620 driver.
- After restarting with driver signature enforcement disabled, go to Device Manager > Display adapters.
- Right-click on your generic display adapter (or the current Intel graphics entry, if any) and select Update driver > Browse my computer for driver software > Let me pick from a list of device drivers on my computer > Have Disk….
- Browse to the folder where you extracted the Intel driver files and select the modified igdlh.inf file (it might be just named “igdlh” in the “Graphics” subfolder).
- A red warning message will appear stating that the driver is unsigned. Choose “Install this driver anyway”.

During the installation, you might notice your screen brightness automatically adjusts. Once completed, you should now be able to control your screen brightness using the F2 and F3 keys on your HP laptop.
Conclusion
Congratulations! By following these steps, you have successfully installed both your dedicated and integrated graphics drivers on your HP laptop running Windows 8.1. This process not only ensures your graphics cards are functioning correctly for optimal performance but also resolves common issues like screen brightness control. Enjoy the full visual potential of your HP laptop!
