RADEON X700/X550 Series Secondary (Microsoft Corporation - WDDM) Driver

The RADEON X700/X550 Series Secondary (Microsoft Corporation – WDDM) driver helps Windows communicate with the secondary display function exposed by compatible AMD/ATI Radeon graphics hardware. It is relevant when this legacy device appears in Device Manager with a missing driver, a warning icon, or display configuration problems.

Key Features

• Device recognition: Helps Windows identify the secondary graphics function on compatible Radeon X700/X550 hardware; this entry does not necessarily indicate a separate graphics card.
• Display configuration: Can support resolution, color, and additional-display settings when paired with a compatible primary graphics driver and supported hardware.
• Windows graphics integration: The WDDM designation identifies a Windows Display Driver Model driver, rather than a separate graphics utility.
• Legacy driver matching: Provides a device-specific starting point for finding a suitable package, although compatibility depends on your hardware ID, Windows version, and system architecture.

How to Install RADEON X700/X550 Series Secondary (Microsoft Corporation – WDDM) Driver

1. Check your device details. Open Device Manager, locate the Radeon secondary entry, and select Properties > Details > Hardware Ids. Also confirm your Windows version and whether it is 32-bit or 64-bit.

1. Verify package compatibility. Before choosing a RADEON X700/X550 Series Secondary (Microsoft Corporation – WDDM) driver download for Windows, check the package’s supported hardware and operating systems. Listings may cover Windows 10, 8.1, 7, Vista, and XP, but one package may not support them all. Windows XP uses a different driver model, so this WDDM package is not interchangeable with an XP driver.

1. Download a suitable package. Choose a trusted free download source and look for the latest version explicitly compatible with your device. For Windows 10/11, do not assume legacy Radeon support: Windows 10 compatibility requires verification, and Windows 11 support should not be inferred from this listing.

1. Install the driver. Create a restore point, then run the compatible installer. If the download contains extracted driver files instead, use Device Manager > Update driver > Browse my computer for drivers and select their folder.

1. Restart and test. Reboot, check Device Manager for warnings, and confirm that your resolution and connected displays work correctly. If problems begin after installation, use Roll Back Driver where available.

Keep the driver updated only with releases that explicitly match your hardware and operating system. For legacy graphics, a stable, compatible driver is generally a better choice than an update intended for a newer Radeon family.
