The AMD Radeon HD 8490 driver helps Windows communicate with your graphics card so it can display the desktop correctly and run supported graphics applications. Installing a compatible AMD driver can restore missing resolution options, enable hardware acceleration, and replace the limited functionality of the Microsoft Basic Display Adapter.

Key Features

• Display configuration: Provides access to supported screen resolutions, refresh rates, and monitor settings based on your display and connection.
• Graphics acceleration: Enables the GPU to handle supported rendering tasks in desktop applications, video playback, and compatible games.
• Multiple-display support: Allows connected monitors to work together where supported by the card’s outputs and your system configuration.
• AMD graphics controls: Compatible driver packages may include an AMD control panel for adjusting display and application-specific graphics settings.

How to Install

1. Confirm your hardware and Windows version. Open Device Manager and check the entry under Display adapters. Verify that your card is the AMD Radeon HD 8490, then check your Windows edition and whether it is 32-bit or 64-bit.

1. Choose a compatible driver package. Match the download to your operating system: Windows 11, Windows 10, Windows 8, or Windows 7. This is a legacy GPU, so compatibility varies by driver release. Do not assume an older package officially supports Windows 11; review its supported-device and operating-system information first.

1. Prepare for installation. Save your work and close running applications. If the graphics card came preinstalled in a branded desktop, check whether the computer manufacturer recommends a customized driver.

1. Run the installer. Extract the package if required, launch the setup program, and follow the prompts. Your screen may flicker or briefly go blank while Windows updates the display driver. Avoid interrupting the process.

1. Restart and check the result. Reboot if prompted, then confirm that Device Manager lists the card without a warning symbol. Open Windows display settings to select your preferred resolution and arrange any additional monitors.

If installation fails or display problems appear, use Device Manager’s Roll Back Driver option when available. Avoid forcing a package intended for a different GPU or Windows version.

Common Issues and Fixes

• Install fails or rolls back: The HD 8490 is a legacy/OEM card, so current AMD Adrenalin packages may not support it. Use the correct legacy Catalyst driver for your Windows version, run the installer as administrator, and clean old AMD drivers with DDU first.
• Device not detected: Check Device Manager for the card and warning icons. Reseat the PCIe card, confirm it is enabled in BIOS, and try another slot if available.
• Version conflicts / Windows Update overwrites driver: Windows may replace the AMD driver with a generic or unsupported version. In Device Manager, roll back or manually select the legacy driver, then pause automatic driver updates for that device.
