The scan rate of most computer monitors is closely related to multiples
of the scan rate of a NTSC television signal scan rate.

How do you work that out? NTSC is 60Hz (30Hz Interlaced)
So Most CRT monitors run at 70Hz, 75Hz, 85Hz and maybe 100Hz for a high end
monitor at 1024*768

Where is the link between the vertical refresh rates?

Have a google search for Vesa refresh rates for more info.

pulled out of manufacturing them in the UK)
