CRT screens definitely used pixels, but they updated on the horizontal line rather than per pixel. This is why earlier flatscreen LCDs were worse than CRTs in a lot of ways as they had much more motion blur as stuff like “sample and hold” meant that each pixel wasn’t updated every frame if the colour info didn’t change. CRTs gave you a fresh image each frame regardless.
I have heard that pixels in CRTs are round and LCD/LED are square, that’s the reason why aliasing is not too noticeable on CRTs. Is this true or another internet bs?
They’re not round persay, but they aren’t as sharp so have more light bleed into one another giving a natural alaising effect. This is why some old games where the art is designed to account for this bluring look wrong when played on pixel perfect modern TVs.
What they’re referring to is that analogue CRTs don’t really have a fixed horizontal resolution. The screen has a finite number of horizontal lines (i.e. rows) which it moves down through on a regular-timed basis, but as the beam scans across horizontally it can basically be continuous (limited by the signal and the radius of the beam). This is why screen resolutions are referred to by their vertical resolutions alone (e.g. 360p = 360 lines, progressive scan [as opposed to interlaced]).
I’m probably wrong on the specifics, but that gives the gist and enough keywords to find a better explanation.
You kinda can tell though. CRTs didn’t really use pixels, so it’s not like watching on today’s video equipment though

Noted.
Ummm…what? How do you think did CRTs show the picture?
