What determines the max refresh rate of a CRT?
I'm confused as to how the max refresh rate of a CRT is decided.
My F520 monitor says to have a max refresh rate of 170. However, using a calculator, a 640x480 signal at 280hz would be within the bandwidth and scanning frequency of the monitor. Why is it set to 170, what would happen if I push it past that? (I'm a little cautious of actually trying)
Would interlacing the video also push the refresh rate to 340hz since the electron beam is essentially moving at the same pace?
I don't really care about having that high of a refresh rate, i'm just curious to know.
