Radeon X1300 / X1550 Series Secondary (Microsoft Corporation - WDDM) Driver

The Radeon X1300 / X1550 Series Secondary (Microsoft Corporation – WDDM) driver helps Windows recognize and operate the secondary display function associated with these legacy AMD/ATI graphics adapters. It is useful when Device Manager shows a missing display driver, a secondary monitor is unavailable, or Windows offers only limited resolution options.

“Secondary” typically refers to an additional display function of the graphics adapter rather than a separate graphics card. Although this device may appear under “Other” when its driver is missing, it belongs to the graphics hardware category.

Key Features

• Display adapter recognition: Helps Windows identify the secondary Radeon X1300 / X1550 display function instead of leaving it as an unknown device.
• Resolution and color settings: Enables supported display modes when the correct driver is installed for your hardware and operating system.
• Multiple-display support: Helps manage additional display outputs where supported by the graphics card, connected monitors, and driver package.
• Windows graphics integration: Provides the appropriate interface between the adapter and Windows; WDDM functionality requires a compatible Windows version and driver.

How to Install Radeon X1300 / X1550 Series Secondary (Microsoft Corporation – WDDM) Driver

1. Check your system details. Open Device Manager, locate the display adapter or unknown device, and check its hardware IDs under Properties > Details. Confirm your Windows version and whether it is 32-bit or 64-bit.
2. Choose a compatible package. Before selecting a Radeon X1300 / X1550 Series Secondary (Microsoft Corporation – WDDM) driver download for Windows, verify that the package matches your hardware and OS. Windows 10, 8.1, 7, Vista, and XP require version-specific checks; XP uses a different driver model, not WDDM. Windows 10/11 compatibility should not be assumed for this legacy hardware.
3. Download and prepare. Select a trusted free download source, review the package information, and extract the files if necessary. Create a restore point before making changes.
4. Install the driver. Run the included installer, or select Update driver in Device Manager and browse to the extracted driver folder. Avoid forcing a package that Windows identifies as incompatible.
5. Restart and test. Restart your computer, check Device Manager for warnings, and confirm that your monitor resolution and secondary display settings work correctly.

Keep the driver updated when a verified compatible update is available. For older Radeon hardware, the latest version is not necessarily the best match: prioritize the last supported release for your adapter and Windows edition over a newer, unrelated package.
