>>2909681>They do not have 0 input lag, they display their picture progressively in scanlines so it does not happen instantlyNot what that means. On a CRT, the scanning is controlled directly by the signal from the console. While, obviously, the frame takes time to draw, it follows the (analog) input signal as it gets it. That is to say, between the output of the console and the screen itself, there is effectively no delay. An LCD has to sample, convert, process, and then draw the signal, all of which takes some time.
This used to be a genuine problem, with shitty TVs having delays of potentially 2-3 frames between the console outputting a frame and the screen actually showing it. The worst ones could have 100ms+ of delay, which was jarring even in relatively slow, single-player games. I would know: I played on a few of them.
Either way, this is far less of a problem than it used to be. Most TVs now will do <10ms on game/low-latency mode, around half that if they can do 120hz. The fastest gaming monitors reach under 2ms. It's not really worth dealing with a CRT these days, even if you are giga-autist in the FGC. The only reasons you'd be looking to buy one are that you're a collector/preservationist or have been bamboozled into thinking they're still worth it by some nerd on YouTube.
