Appendix B. Additional Information
B-1. Checking DirectX Version and Video Information
When installing your USBCam2, you will be prompted to install the latest version of
Microsoft's DirectX files on your system (DirectX 9). We strongly recommend that you
install these files as earlier versions of DirectX prior to DirectX 8.1 are not compatible
with USBCam2. In the event you experience video problems with USBCam2, please
verify that your system has properly installed DirectX version 8.1 or later by performing
the steps below.
Video quality and performance is also affected by the amount of video memory available.
By running dxdiag.exe, as documented below, and checking the Display tab, you can
verify the amount of video memory available on your graphics card.
STEP 1
A. At the Windows desktop, click Start, Run, and then
type dxdiag.exe.
B. The "DirectX Diagnostic Tool" dialog box is
displayed.
C. Under the System tab, verify that your current DirectX
version is 8.1 or higher.
STEP 2
A. If your DirectX version is 8.1 or higher, you have the
correct version for USBCam2 operation. Click Exit to
close this dialog box.
B. If your DirectX version is less than 8.1, repeat the
installation steps found in the “Software Setup”
section of this manual.
