Brightness: The brightness of a projector is measured in lumens. The more light in the room where the projector is used, the brighter the projector.
Contrast ratio is the ratio between dark and the brightest of the projected image. Average contrast ratio projectors can be found with a ratio of 500:1 to 1200:1.
Ports of data signals: These ports on the projector must be compatible with any image source, it will be paired with.
Keystone Correction: It is the ability to distort the image that arises when the projector is not more than a 90-degree angle to the screen is placed right.
