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 maximum size of image that a device can project without compromising quality.
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.
You can control the focus remotely, ensuring that the image stays crisp and clear.
