Default Monitor Refresh Rate is Too High for Monitor
=======================================================================

DESCRIPTION

Environment: Monitor requiring 60 Hz refresh (for 640x480x16 or 256)
             Diamond Stealth PRO S386C98 (may occur with other video 
             adapters)

Installing OS/2 Warp 4 with Diamond Stealth Pro video drivers and 
selecting 640x480 (x16 or x256) resolution sets the monitor refresh 
rate too high for a monitor which requires a 60 Hz refresh rate. 
The result is distortion on the monitor;
either the viewable area on the screen is very small, the screen 
flickers, or the entire screen is unreadable.

RESOLUTION

These problems are resolved by the utilities shipped with either the 
monitor or with the video adapter. In the case of the Diamond Stealth 
PRO S386C98, use the STLMODE.EXE utility shipped with the adapter, 
as follows:

1. Insert the Diamond Setup Program Diskette in drive A:. From a DOS 
   Full Screen session, change to the A: drive and type STLMODE, then 
   press Enter.
 
2. Select the Custom Monitor setting and display centering for the 
   640x480x256 mode.

3. Press Esc to exit out of the program. 

This leaves the monitor with the correct refresh rate, even after 
subsequent system restarts.

Note: Reinstalling the video driver (S3 801,805,928) using 'default 
      settings for monitor' rather than using 'display adapter utility'
      program has no effect on the problem.

      Running 'SVGA ON' at any time causes the monitor refresh rates 
      of the current desktop session to be corrupted.
