Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
The light projected by the device is brighter, i.e. it has a higher ANSI lumens measurement.
Motorized or power zoom lenses allow the user to remotely press a switch, for example on a remote control, causing the projector to automatically zoom in or out and correct the size of the image.
A projector zoom allows you to increase or decrease the size of the projected image without moving the projector. The most common zoom ratio among today's projectors is 1.2, which means you can vary the image size by 20% by simply adjusting the zoom lens.
This allows you to manually set the focus.
It supports displaying 3D images from devices such as a 3D-compatible Blu-ray player, allowing you to watch films in 3D when using suitable glasses.
