Monitor settings 9
Setting up your monitor in
OS/2 Warp
These are the monitor settings that you can select if you
purchased a computer with OS/2* Warp preinstalled.
•
Screen Resolution. Determines the amount of
information and the number of colors that can be
displayed on the screen.
•
Screen Refresh Rate. Sets the speed at which the
entire image is drawn on the screen.
The values you can choose for Screen Resolution
depend on the:
•
Horizontal frequency setting your monitor supports.
•
Screen resolution and screen refresh rate settings
your monitor supports.
•
Amount of video memory installed on the
computer’s system board. The amount of video
memory installed on your system board is listed in
the Configuration Utility. For instructions on using
the Configuration Utility, see page 63.
Tips:
Of the settings that your monitor supports, you should
select the ones that are most comfortable for you to
work with. The highest resolution and color settings are
not always best. For example:
•
Higher resolutions display more pels (picture ele-
ments). While this allows more text and graphics to
be displayed, it makes them appear smaller. For
most users, 640x480 or 800x600 is a comfortable
resolution setting.
•
When you select more colors, most software
applications will slow down. Only choose as many
colors as you need. A color setting of 256 typically
provides the fastest performance.
•
You can determine which settings are most
comfortable to work with by selecting and trying
each one.
