| Check DirectX components with Dxdiag |
| DirectX, a Microsoft technology that provides multimedia services to Windows users, comprises |
| several application programming interfaces (APIs) that provide video, audio, and input services for |
| high-performance multimedia. |
| If you need to determine a version number, troubleshoot, or configure settings for DirectX, use the |
| DirectX Diagnostic Tool, Dxdiag. To use the diagnostic tool, open a command console and enter |
| DXDIAG at the command prompt. |
| Dxdiag provides a tabbed dialog box that offers extensive information about DirectX version, |
| installed files, and drivers. Use the Display tab to view and change display settings and to perform |
| tests for DirectDraw and Direct3D. Use the Sound tab to configure audio acceleration and test |
| DirectSound. Additional tabs enable you to view and test other DirectX components for networking, |
| input, and other audio properties. |
| Dxdiag is useful when troubleshooting application problems. With Dxdiag, you can export all |
| DirectX properties to a text file, which your users can forward to you and which you can forward to |
| Microsoft Support Services if necessary. |
