Secondary VGA Monitor Loses Synchronization with 8514 Driver

 * }

Q82432

-

The information in this article applies to:


 * Microsoft Windows versions 3.1, 3.11

-

SYMPTOMS
Using 8514 as the primary display, and a built-in VGA as the secondary display, you may get unreadable characters on the secondary VGA monitor (the secondary monitor appears to lose its synchronization signal) when switching from MS-DOS Prompt in full-screen mode back to Windows.

WORKAROUND
When this problem occurs, Microsoft recommends that you try to switch back to the MS-DOS Prompt in full-screen mode, then back to Windows to try and change the state of the VGA monitor because this situation can stress the monitor.
