I would like to know what determines the maximum resolution of a
monitor.

How do the horizontal and vertical scanning rates, bandwidth, and
dot pitch come into play or do they?

I have a Mitsubishi 1371A multi scanning monitor with the following
specs:

Bandwidth     :  30Mhz            (from a Byte review)
Max Resolution:  800 X 560        (Mitsubishi spec)
Horizonatal   :  15.6-35Khz       (Mitsubishi spec)
Vertical      :  45-75hz          (Mitsubishi spec)
Dot Pitch     :  0.31mm           (Mitsubishi spec)

I currently have EGA and am looking to upgrade to VGA. The question
I have is whether my monitor will handle 800X600 resolution of say
the Paradise VGA Plus 16 card. Will I see 800X600 or not?

This is a major issue in my purchase plans. I am a windows user and 
want the max resolution I can get with my current monitor.

The 2 cards I am looking at most are :

Paradise VGA Plus 16  800X600 windows driver
Video 7 Fastwrite     720X540 windows driver

Also could someone shed some light on the "800X600 Flicker" issue
that I have heard about?

What is Video 7's BBS number? Does Paradise have a BBS?

Any help, hints, etc. would be greatly appreciated.

Glenn
