go track the ufo with your eyes while it moves, itll appear blurry
this is called motion blur, its caused by the way flatscreens work
CRTs shoot a beam of electrons on a phosphorus surface in a grid as big as you want it to be (e.g. 640x480)
it goes from the top left to the right, then starts the next line, etc..., the same way you are reading a page of text, until it hits the bottom and goes up
once it hits the bottom it completed a frame, this happens for example 60 times per second, now guess how many electron beams are shot on phosphorus per second
in LOW RES, you get 307200 dots projected onto your screen every frame, this 60 times per second, so you get 18432000 dots per second.
dont even get me started on high resolutions like 2K or 1200p...
2880x2160@60Hz gives you 373248000 dots per second, its impressive how powerful CRTs were and still are, especially compared to shitty flatscreens
in the duration while the electron beam moves back up, it doesnt illuminate anything, and your screen is technically black
your eyes are tricked into believing that its a solid image because it happens 60 or 80+ times per second, on 50 or 60hz you can see a bit of flicker, this is caused by the black intervals, and by the fact that a spot of phosphorus isnt illuminated for the entire time a frame is displayed.
flatscreens just keep a solid image until the colour of a pixel changes, that means you dont get flickering. if anything on screen moves and your eyes go along with it, you will see it as a blurry mess because pixel response times arent zero or get blacked like on CRTs or anything that flickers.
>inb4 flickering rapes my eyesyou dont actually SEE the flicker on 70-80Hz, and on 60hz you get used to it, if you dont have a completely white image you wont see it after some time. theres a reason why CRT monitors are designed for 70-90Hz (and above/below that, but generally around that range)
it depends on your eyes, 70-80hz is the sweet spot for just enough hz to eliminate flicker, but not much wasted gpu power.
you can also set your CRT to the native refresh rate of whatever you are playing back, like some video game locked to 60hz or a video at 90
this eliminates doubled images, like in pic rel
