> CRTs are potentially worse. It takes the electron beam 16 ms to paint the screen. If the electron beam is halfway down the screen and you change a pixel right above where the beam just painted, you'll have to wait 16 ms before you see anything change.
This is exactly the same as LCDs though, no? LCDs are also drawing an entire frame at a time, they're not "random access" for lack of a better term. There's just typically no image processing going on with a CRT* though, so there's no inherent latency beyond the speed of the electron gun and the speed of light.
*I'm aware there were some later "digital" CRT models that did analog->digital conversion, followed by some digital signal processing on the image, then digital->analog conversion to drive the gun.
