This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Can someone please explain why CRT is 0 blur and 0 latency when it literally draws each pixel one-by-one using the electron ray running across the screen line-by-line?
Because it is analog. There are no buffers or anything in between. Your PC sends the image data in analog throug VGA pixel by pixel. These pixels are projected instantly in the requested color on the screen.
Of course there's buffers. Once RAM got cheap enough to have a buffer to represent the whole screen, everyone did that. That was in the late 80s/early 90s.
There's some really bad misconceptions about how latency works on screens.
Those are on the graphics adapter. Not in the CRT.
You can update the framebuffer faster than the CRT can draw. That's when you get tearing. Same VSync then as now.
