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.
3.maximum projection size
The maximum size of image that a device can project without compromising quality.
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.
5.displays 3D with glasses
The screen can be used to view 3D images with special glasses. The advantage of these screens is that they provide wider viewing angles compared to devices that don't require 3D-compatible gear.
The frequency at which the screen is refreshed. Higher frequency results in less flickering (less noise) and more natural movement representation in action-intense scenes.
