Monitor Refresh Rates
The drop-down list boxes let you select the monitor refresh rates for each resolution. If you select
None for any screen resolution, any higher resolutions will also be unavailable. This also turns off
the corresponding choices in the Resolution box.
The only choices that are available are those available to the monitor which was selected in the
Monitor Brand and Monitor Model fields. If Other Brand or Other Model were selected, all of
the refresh rates available on the graphics adapter are listed. Consult the manual that came with
your monitor to determine the best choices.
In general, the higher the refresh rate, the better the display quality and the lower the performance.
This is because the graphics system can only do a fixed number of operations per second. The
more time it spends redrawing the screen, the less time it has available to perform other operations.
Resolution
These buttons let you choose the resolution which WinMode will use to run Windows 3.X after
Windows is restarted. Some of these buttons may be unavailable because of the amount of video
memory in your system or if some of the monitor refresh rates have been set to Unavailable.
Colors
These buttons let you choose the number of colors which will be available to Windows 3.X after
Windows is restarted. Some of the selections may be unavailable because of the amount of video
memory in your system and the resolution you have selected. If you have chosen OS/2 v2.1 in the
Operating System field, the only possible choices are for 16 or 256 colors. Generally, 256 color
mode provides the best performance. If you need more colors there will be some slowdown in
graphics performance.
Font Size
The small fonts are intended for lower resolutions and higher resolutions on large monitors. With
smaller monitors, the large fonts are more readable at higher resolutions.
Font Cache Size
The Font Cache Size lets you set the amount of system memory which is available for font cach-
ing. Next to the font cache size are an up arrow and a down arrow. Click on the up arrow to
increase the cache size. Click on the down arrow to decrease the cache size.
Font caching is a technique to increase the performance of Windows by saving the bitmaps of
frequently used characters. Normally, when a character is displayed on the screen it first is created
from the TrueType outline and then is copied to the screen. A cached character has already been
created and stored and so it is just copied as needed. WinMode has tried to determine the correct
setting for this field for you, but you may change it. However, remember that memory set aside for
font caching is not available for Windows program and system usage.
