Then in win-98, remove your monitor in device manager.

When I do that (in fact, I just now did it) there is no choice on setting a
refresh rate, not even default or optimal.
Perhaps I will try installing PowerStrip and try it again before I install
another monitor.


Ignore any "found new hardware" messages that might happen after that.

No messages happened.

Your display properties should then no longer show the Envision
monitor. You should then be able to select a refresh rate like you do
in win-2K.

Display Properties now doesn't even have a monitor tab and no refresh rate
choices in the Adapter tab.

There is no choice for refresh rate when I remove the Envision Monitor in
Win98SE.
In Win98SE, the ATI drivers do not include the Catlyst Control Center, which I
used in Win2000 to uncheck 'use EDID or default' and then set the max resolution
and max refresh rate manually.
However, in Win2000, I again installed the Envision 910 monitor and it worked
fine as long as I have the 'use EDID or default' box unchecked.


Does the monitor dispay the refresh rate on-screen? Are you sure that
win-2K is driving it higher than 60 hz?

Yes, the monitor refresh rate does show on the screen. I also used another
program , osd.exe, to double check the refresh rate.

You seem to be saying that the monitor has somehow "lost" it's
internal EDID information. I don't know how such a thing is possible.

When I use ddctest.exe for info, it reports an "invalid or checksum" and that
the 'monitor microprocessor is not responding'.

But if you are able to drive it higher than 60 hz in win-2K, then
win-98 should do the same.

I am hoping to do that , but it seems that the vid card (while in Win98SE) needs
to communicate with the monitor.
I don't understand why.
I will try installing PowerStrip now, without rebooting, hopefully.
