Go to the monitor manufacturer’s support website (e.g., Dell, HP, AOC, MSI), and navigate your way around the website until you find an option to download drivers. Enter your monitor model name, go to “Downloads” (or equivalent), and download the driver. While you’re here, you might as well download the monitor’s software. You can use it to configure your monitor profiles, colors, brightness levels, etc.

After the driver has been downloaded, run it and follow the on-screen prompts to install it. If it’s an INF file and a few other potential files rather than an EXE (executable), don’t fret. You’ll just have to install it manually. Open the Windows Start Menu and type “Device Manager,” then click to open it. Navigate to “Monitors” and find your monitor. If you have more than one monitor, and all of them show up as “Generic PnP Monitor,” try disconnecting all but the one you’re trying to update. Then, right-click it and select “Update Driver.” Select “Browse my computer for drivers”.

Then select “Browse,” and locate the folder that contains the monitor driver’s INF file.
