In the context of the Amiga you didn’t need to change the signal frequency, the underlying video signal stayed the same.
For wider pixels, the hardware just drew each pixel for longer, and for taller pixels each pixel spanned more lines.
Pixels weren’t real in the CRT days :)
In a sense pixels arent even real today right? It's an abstraction
Kinda, but a CRT literally doesn’t have precise pixel targeting in the way an LCD does. Instead, you’re telling the electron gun to draw red for a little while, and it paints what it paints.
LCD and OLED panels consist of a fixed, unchangeable matrix of native pixels. (Same for the discontinued Plasma TVs.) CRTs don’t have that.
