Hello All,

I have the above configuration running in an Elonex 486 50MHz DX machine and would 
like to have a resolution of 1152x800. However, using the card at this resolution
with a dot clock of 96 MHz leads to a lot of pixel dropouts in certain colours. I
changed to the same resolution at 80MHz which diminished the pixel dropout problem, 
but it didn't cure it completely. I was wondering if anyone else had a similar problem
or knew that what I am trying to do is beyond the capability of the card. Could this
be related to the caveat in the manual page regarding running RAMDACs at 80MHz and
beyond?

The card is ISA and has 1MB of RAM and uses a S3 911 chip. The monitor is a SONY
CPD 1704S. Please e-mail me if you have any ideas regarding this problem and if there is interest I will summarize to the net.

Thanks,



Tom.
