A+: DxDiag
When it comes to making sure your devices are
working properly, one of the most important is the video card, and a
utility you can use to analyze and diagnose the video card is DxDiag
.
To run the DxDiag program, open the Run prompt and type dxdiag.
First,
the utility asks if you want it to check whether the corresponding
drivers are digitally signed. A digitally signed driver means it is one
that has been verified by Microsoft as compatible with the operating
system. After the utility opens, you can find out what version of
DirectX you are running.
DirectX is a group of multimedia programs that
enhance video and audio, including Direct3D, DirectDraw, DirectSound,
and so on. With the DxDiag tool, you can view all the DirectX files that
have been loaded, check their date, and discern whether any problems
were found with the files. You can also find out information about your
video and sound card, what level of acceleration they are set to, and
test DirectX components such as DirectDraw and Direct3D. Windows 7 ships with DirectX 11, Windows Vista
ships with DirectX version 10, and Windows XP currently can use up
to DirectX 9.0c.
The latest DirectX features are important to
video gamers and other multimedia professionals.
