A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics
- NEW RULE as of 5 Nov 2024, trying it out
- Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct-----

You kinda can tell though. CRTs didn’t really use pixels, so it’s not like watching on today’s video equipment though
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.
Noted.
Ummm..what? How do you think did CRTs show the picture?
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.
