Not quite… There is some attenuation due to the medium, in this case, signals sent by wire. Even optic fiber has some attenuation.
Obvious troll, but I’ll explain it to the rest of you guys: the latency in CRTs is so miniscule compared to LCDs that it might as well be called instant.
When one of your times is in milliseconds, while the other requires awareness of relativistic effects, you might as well call it instant.
The propagation speed in copper is 2/3 C. With analogue monitors, that was effectively amped and thrown at the screen. The phosphate coating is the slowest part, that takes 0.25-0.5ms to respond fully.
By comparison, at the time, “gaming” LCD screens were advertising 23ms response rates.
