Blurred strip accross dsktp (ET4000 chip 6/02/94
File:SPEED.fax
TITLE: VIDEO GOES OUT OF SYNC OR A BLURRED STRIP APPEARS
ACROSS THE TOP OF THE DESKTOP USING TSENG ET4000 ADAPTERS
IN SVGA.
DESCRIPTION OF SYMPTOMS:
The display screen will loose sync or a blurred strip
appears across the desktop. This can happen on boot up or
when switching between full screen sessions.
SUMMARY OR RESOLUTION:
1. Make sure the BIOS is at it latest revision and the
batch # on the chipset is TC6059AF or higher. Then run the
display adapter utility that come w/ the adapter card to
set the proper refresh rates for your monitor. Next,
regenerate the svgadata.pmi file.
DETAILS OF RESOLUTION: 1. Make sure the batch # on the
chipset is TC6059AF or higher and make sure the BIOS is at
its latest revision as well(Diamond's should be at least
4.23).
2. Use "RSPDSPI" to set video mode back to vga.This
step is not always necessary but if the desktop is not
useable it must be done. If the desktop can be used go to
step 6.
3. Open a DOS full screen session and run "svga on".
4. Then exit.
5. Open an OS2 full screen session and run "DSPINSTL"
to install the svga drivers. DO NOT SHUT DOWN WHEN
PROMPTED!
6. Open a DOS full screen session and run the display
adapter utility that came w/ the display adapter
card. Diamond's utility is called "vmode". With
this utility you will set the refresh rates for your
monitor. The higher you set the refresh the better the
performance of your monitor but do not exceed the
limitations of the monitor(See the specifications).
7. Regenerate the svgadata.pmi file by running "svga
on".
8. Exit DOS fullscreen.
9. Shutdown and reboot the system.
NOTE: For OS2 FOR WINDOWS use SELECTIVE INSTALL instead of
DSPINSTL in step 5.
