    Yeah I didn’t think it would make the “pixels” smaller, but the beam would need to pulse less often and therefore could travel more. Maybe I’m misunderstanding what they did.

      Electron beams scan insanely fast, that isn’t the limiting factor. Getting that much bandwidth across a VGA cable is tough. If you wanted super high refresh rates on old CRTs you’d have to drop the resolution. Same concept.

        Ah. I see, so reducing the resolution was more about sending frames to the monitor faster, not about optimizing the tube hardware’s behaviour

          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.
