Why LCD screens are "blue" when shooting?

Question

Surely you have noticed that when shooting an LCD monitor or TV with a digital camera or camera, they give off in blue (or blue). What is it connected with? It seems that in the RGB matrix there is more green than blue and red, if I'm not mistaken. So where does this "blueshift" come from?

Answer 1

> But this effect is visible on prof. video cameras, for example, in all news stories on the box, monitors and TVs go blue. Or do they also have trouble with white balance?
imagine that you have 2 light sources in your room: an incandescent lamp (i.e. an ordinary light bulb) and a monitor. to know so that the screen is white and the light from the lamp is not yellow will not work, they have different temperatures. those. option 2: either the screen is blue, but everything else is more or less normal; or the screen is white, but everything is yellow-orange. you need to choose the lesser of two evils :)
right now I'll click a couple of pictures to make it clear :) otherwise I can't explain it in words.

Answer 2

it's because your cameras suck :) they incorrectly determine the white balance and set the "incandescent lamp" mode when it is not needed.

Answer 3

UV shift to blue.
