So why does this happen? The answer comes down to four things:
1) Pixels – tiny dots in digital imaging that come together to form a picture
2) RGB color– red, green, and blue pixels that come together to produce a variety of new colors
3) Bit depth – the number of bits used to indicate the color of a single pixel; the higher the bit depth, the more RGB pixels on the screen and the more accurate the color
4) Display resolution – the number of distinct pixels in each dimension that can be displayed
The pixels are in some pattern of red, blue, or green depending on the bit depth, a.k.a. how many can fit on the screen. If one monitor has a higher bit depth than the other, it will affect the resolution, which in turn, affects how visual content, namely color, shows up on the screen.
