another really really common thing-

is that people run multiple monitors out of a computer at different sizes and refresh rates-
sometimes they run a triple head and a single screen-

with this - the refresh rates are different to each monitor

vga/dvi have different refresh rates at different sizes-

for 60Hz its somewhere between 60.04 and 59.95

dvi and vga are not constant frame rates at different screen sizes.

then they do video input - at 25 or 29.97 -

an enormous number of possibilities - i try to do the best possible thing for these complex scenarios.

i found a vga frame rate calculator at :
