The AMD Radeon HD 8790m is a dedicated laptop GPU, and its driver allows Windows and applications to communicate with the graphics hardware. Installing a compatible AMD graphics driver helps enable hardware acceleration, proper display settings, and reliable rendering in games and everyday software.

Key Features

• Graphics acceleration: Enables supported applications to use the GPU for rendering, helping with desktop visuals, video playback, and compatible games.
• Display configuration: Provides access to supported screen resolutions, refresh rates, and external monitor options, depending on your laptop’s connections and display capabilities.
• AMD graphics controls: Compatible driver packages may include settings for adjusting image quality, application profiles, and other graphics preferences.
• Laptop graphics integration: Helps the Radeon GPU work with your notebook’s graphics configuration. Systems with switchable graphics may require manufacturer-specific drivers for correct operation.

How to Install

1. Check your Windows version and hardware. Open Device Manager and look under Display adapters to confirm that your laptop uses the AMD Radeon HD 8790m. Check whether Windows is 32-bit or 64-bit before selecting a download.

1. Choose a compatible driver package. Match the download to Windows 11, 10, 8, or 7 as applicable, and verify the package’s actual compatibility notes. This is a legacy GPU, so official driver availability varies; do not assume an older package officially supports Windows 11 simply because it installs.

1. Prepare your laptop. Save your work, close running applications, and connect the power adapter. Creating a restore point is a useful precaution. If your laptop uses switchable graphics, check the manufacturer’s installation guidance before replacing its graphics drivers.

1. Run the installer. Extract the downloaded archive if necessary, then launch the setup program and approve the administrator prompt. Follow the on-screen instructions. Your display may briefly flicker or go blank while the graphics driver is being updated.

1. Restart and verify operation. Reboot when prompted, then check Device Manager for warning icons. Confirm that the screen runs at its native resolution and test video playback or a familiar application. If installation fails or graphics switching stops working, try the driver recommended by your laptop manufacturer rather than forcing an unsupported package.

Common Issues and Fixes

• Installer reports no compatible hardware: The HD 8790M is an OEM laptop GPU and may be absent from newer AMD packages. Use your laptop vendor’s driver or an AMD legacy/Catalyst package that explicitly lists the HD 8790M; don’t force unsupported INF files.
• GPU not detected in Device Manager: Confirm the discrete GPU is enabled in BIOS/UEFI and switchable graphics is configured correctly. Reinstall the laptop chipset and AMD switchable-graphics driver.
• Version conflicts or Code 43: Remove old AMD/Windows Update drivers with DDU in Safe Mode, block Windows from auto-replacing the driver, then install the matching OEM/legacy driver.
