The AMD Radeon HD 6790 driver enables Windows to communicate with your graphics card, providing hardware acceleration, display controls, and graphics support for compatible applications and games. Choosing the right AMD driver can help resolve issues such as incorrect screen resolution, missing display settings, or limited graphics performance.

Key Features

• Graphics acceleration: Enables the Radeon HD 6790’s rendering capabilities for supported games, desktop effects, and graphics applications.
• Display configuration: Provides controls for supported resolutions, refresh rates, and multiple monitors, depending on your connections and installed driver package.
• Video playback support: Allows compatible media software to use GPU-assisted video decoding, helping reduce processor workload.
• AMD graphics settings: Compatible packages may include AMD Catalyst Control Center for adjusting image quality, display behavior, and application-specific graphics options.

How to Install

1. Check your Windows version and system type. Confirm whether you are using Windows 11, Windows 10, Windows 8, or Windows 7, and whether the installation is 32-bit or 64-bit. Select a package that explicitly lists your operating system and the AMD Radeon HD 6790.

1. Verify legacy compatibility. This GPU uses legacy AMD drivers rather than current Radeon software. Official driver availability varies by Windows version, and AMD does not provide an officially supported Windows 11 driver for this card. Do not assume that a Windows 10 package will work correctly on Windows 11.

1. Prepare for installation. Save your work, close games and other graphics-intensive applications, and create a system restore point if possible. If you are replacing a different graphics card, remove its previous driver software to help avoid conflicts.

1. Run the compatible installer. Open the downloaded AMD driver package, approve the administrator prompt, and follow the on-screen instructions. Your screen may flicker or briefly go blank while the display driver is being installed.

1. Restart and check the results. Reboot when prompted, then open Device Manager and confirm that the Radeon HD 6790 appears under Display adapters without a warning symbol. Check your screen resolution and test a familiar application. If problems begin after installation, use Device Manager’s Roll Back Driver option when available.

Common Issues and Fixes

• Installer fails or stops early: Use AMD’s final legacy Catalyst package for HD 6000 series; run as administrator, extract manually if needed, and temporarily disable antivirus. Avoid current Adrenalin drivers, which do not support the HD 6790.
• Device not detected: Reseat the card, connect the 6-pin PCIe power, check BIOS for a disabled PCIe slot, and verify Device Manager shows the HD 6790. Try another output/cable.
• Version conflicts/Windows Update overwrites driver: Boot Safe Mode, remove existing AMD drivers with DDU, install the legacy package, then stop Windows Update from replacing it via Device Installation Settings or Group Policy.
