Yeah basically you can only signal “on-off” so many times a second in a vga cable before the ons and offs get blurry and unusable. So you can trade lower resolution for a higher frame rate as long as you keep the total number of on-offs below the limits.
Ah. I see, so reducing the resolution was more about sending frames to the monitor faster, not about optimizing the tube hardware’s behaviour
