Big Screen TV

Big screen is a term used to refer to televisions or monitors with a diagonal (measured from corner to corner) screen size of 35 inches or more. Almost all projection televisions are considered big screen displays.

Bit

The smallest piece of digital data; bits are represented by either a one or a zero. There are eight bits in a byte. All digital devices use bits to transfer information.

Black Level

Black level is the level of brightness or light present in the dark portions of a video image. When no light is emitted from a screen, the result is pure black. Better displays have a high black level (one with little brightness) in the dark areas. A poor video display may have a black level in which the “black” is actually a dark charcoal gray color. When a video display cannot achieve a good black level, the screen will lose some color saturation and appear slightly washed out. Images meant to be black will appear dark gray.

Brightness

Brightness refers to the amount of light in a video image. Increasing brightness makes the image lighter. Decreasing brightness makes image darker.
