Primary Surface mode & DIB Draw

It is sometimes useful to use a mode of operation of your VGA card known as Primary Surface mode or DIB Draw. This can be helpful in eliminating VGA compatibility problems, or improving picture quality on some VGA boards when used in some resolutions.

To use Primary Surface mode, run the program "PRIMARY", which is installed with the WinTV application. Click Start/ Programs/WinTV and then, Click on Primary. Click on Force Primary or DIB Draw then close the program by clicking on the X. The Primary program simply makes a setting in the Windows Registry that tells the application to use the Primary mode or DIB Draw mode of operation.

This can be changed at any time to "Allow Overlay" by re-running Primary and clicking Allow Overlay or DIB Draw.
