I just helpd a friend with setting the display for his computer.
I wondered:
instead of "refresh rates" he has:
vertical frequency, and horizontal frequency.
The vertical frequency is: 85Hz, which is the same as "refresh rate",
As the resolution is 800x600, I gathered that as there are 600 lines
along the vertical axis of the screen, and that thus
horizontal frequency should be
600x85Hz=51KHz,
But the horizontal frequency is set to 53.6KHz, which is of the same
order of magnitude but not the same.

Why is that?
Does it mean that the beam waits (1/51,000)-(1/53,600) seconds before
it is triggered on the next line?  Is that necessary?

Thanks,

Uzi
