What is an RGB signal on a television?

On a television, an RGB signal refers to a video signal that carries separate color information for the red, green, and blue channels.

It represents the three primary colors that, when combined in different intensities, create a wide range of colors and shades on the screen.

The RGB signal allows for accurate color representation and precise control of color balance, resulting in vibrant and lifelike images.

It is commonly used in modern televisions and display devices, providing a high-quality visual experience for viewers.
