How Can I Tell if My Graphics Card Is Compatible With DirectX 9?

By Nick Davis

DirectX 9 works with a PC's graphics card to enhance graphics and sound when running games, videos and programs containing these elements. The software component is free from Microsoft and required by many programs, especially ones containing graphics, 3D animation and advanced sound elements. If your graphics card is not compatible with DirectX 9, you will not be able to run programs that call for it. The software component contains a built-in diagnostic tool that warns you if your graphics card is not compatible.

Step 1

Click "Start," and in the "Search programs and files" box enter "dxdiag." Press "Enter." The DirectX Diagnostic Tool will open.

Step 2

Click the "Display" tab. You will see your graphics card's name and technical information under the "Device" heading.

Step 3

Look under the "Notes" area. If you see "No problems found" or "Certified" listed, your graphics card is compatible with DirectX 9. If any errors stating the graphics card is not found or a conflict has occurred, your graphics card is not compatible with DirectX 9.

Step 4

Click "Exit" to close the DirectX Diagnostic Tool.

Tips & Warnings

  • If running Windows XP, click "Start" and "Run" then enter "dxdiag" in the "Open" box and click "OK" to run the DirectX Diagnostic Tool.
