How do projectors and screens show the color black if black is the absence of light?
In: Technology
They don’t really. They do their best to show no light there and hope the contrast with the bright areas creates the appearance of black.
The physically darkest a screen can get is turned off, so if you just turn off your monitor you can see the blackest black it can create. This can be made darker by reducing the amount of ambient light hitting the screen, which is why if you want a good home theater experience you need to black out the room to make it as dark as possible.
