You also have to emulate an analog signal. With a digital display pixels can go from on to off just like that, however, I doubt that an analog signal really does go from on to off in a perfect 'square wave'. Even then those coils in the electron gun have things like hysteresis to contend with. As for that blurring, on green screen monitors there were no rgb arrangements in the phosphor, it was continual. The blurring was for persistence in a time when refresh rates were orders of magnitude below 100Hz. There was also the small matter of interlacing. Kids today have no idea what that is but it was standard for low refresh rate applications such as a VT terminal. All considered a drop in font is not really up to the job, even if really well designed.
