How does each individual pixel know which colour to represent

Question

I understand the basis of how a single pixel works, but can’t work out how you deliver a specific and exact signal to every single tiny RGB block out of the 2 073 600 existiting in a typical 1080p monitor.

I there individual wiring going out to each one, and if so how are the signals timed and sent out?

You can represent a pixel with 24 bits (= 8 bytes):

11111111 00000000 00000000 is 255 0 0 in binary, which means a red pixel (RGB).

You can also represent a pixel with 4 bytes, and the extra 8 bits (alpha channel) are used to represent brightness/transperency of the pixel.
