alt Hacker News> if you have an LCD or OLED that can do true enough blacks, the effect is very similar to having a brand spanking new CRT, even in arcade applications.
CRTs are inherently less blurry when your eyes follow moving objects on screen, which they do all the time ("smooth pursuit"). The reason is that LCDs and OLED displays show each frame for the entire frame time (like 1/60th of a second) during which your eyes, and the corresponding tracked object, move. This creates a blur. E.g. if an object moves on the screen 10 pixels horizontally per frame, on an LCD/OLED you would then see 10 pixels of horizontal blur. This doesn't happen on CRTs because they flash each frame only for an extremely short period of time and are relatively dark otherwise. At 60 Hz, they don't show the frame for 1/60th of a second, but about 1/1000th or something like that. This time is so short that during it, even fast moving objects and the eyes that track them hardly move at all, which results in basically zero blur. See https://testufo.com/ to see the blur. On a CRT, with matched FPS and Hz, the test would appear completely sharp.
It is true that LCDs and OLED screens are much brighter (especially LCD) and that OLED has better black levels, but CRT screens have much better motion clarity.
CRTs almost never show the entire frame at all. The phosphor decay on a typical television CRT is so rapid that by the time the beam hits the right-hand side of any given scanline, the left side is completely dark.
And unfortunately that motion clarity comes at a cost: flicker. Some people, like my sister, cannot bear that cost. She has photosensitive epilepsy, but even before that ripened into full-on seizures in her 20s she became profoundly uncomfortable playing video games, and never got truly into them until flat panels predominated. Even without photosensitive epilepsy, flicker can be annoyingly perceptible and cause eyestrain even if you don't consciously register it. Most of the motion blur mitigation strategies we see on panels, like black frame insertion, suffer from the same problems. The only way we'll come close to solving both problems at once is with very high speed panels, but until then I'll take a bit of blur, thank you.
