OSVIAVAL - NOT GETTING THE VIDEO RESOLUTION THAT YOU EXPECTED?
11/12/96
=======================================================================
Not Getting the Video Resolution That You Expected?
=======================================================================
Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------
DESCRIPTION
After installing SVGA video drivers without error, the video
resolutions that the adapter and monitor configuration should support
are not listed.
RESOLUTION
The resolution choices available on the Screen tab of the System
Properties notebook, are, for the most part, dependent on what
Graphic Modes were generated into the \OS2\SVGADATA.PMI file.
For some chipsets, it is also important to select the correct monitor
on page 2 of the Screen tab. The monitor choices available are listed
in the \OS2\MONITOR.DIF file. If your monitor is not listed, view the
MONITOR.DIF file with an editor; examine the monitor entries and
compare to the documentation provided with your monitor to find a
comparable match. This match should not include any resolutions where
the refresh rate is higher than what your monitor can support.
Warning: 1. Setting the refresh rate higher than what your monitor can
support can cause damage to the monitor.
2. Do not attempt to manually modify the MONITOR.DIF and
SVGADATA.PMI files. They can be pulled into an editor
to VIEW them but do not save any changes if requested.
If the Graphics Mode entry that you expect is listed in the
SVGADATA.PMI file, check to make sure that the monitor that you have
selected has that as a supported mode in the MONITOR.DIF file.
If the Graphics Mode entry that you expect is not listed in the
SVGADATA.PMI file, try reinstalling the SVGA driver, after renaming or
deleting the existing \OS2\SVGADATA.PMI file. This time, choose
Specific monitor utility, instead of Install using Monitor defaults.
When prompted for the utility disk, use the DOS-based video setup
utility for the adapter. This can be obtained from the manufacturer of
the video adapter, or if the adapter is generic, from the manufacturer
of the chipset. Run this utility during the SVGA driver installation to
assist in generating the correct SVGADATA.PMI file.
