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.
The lens shift feature on a device allows the optical lens to be physically shifted up and down (vertical) or left and right (horizontal).
A bigger variety of brand lenses means that you have more options and can find one that suits your needs.
The device can display 3D images without the need for wearing special glasses. The display's special construction allows viewers to get a sense of an image's depth by tailoring its position to fit the user's perspective.
