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.
You can control the focus remotely, ensuring that the image stays crisp and clear.
This allows you to manually set the focus.
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.
Contrast ratio is the visual distance between the lightest and the darkest colors that may be reproduced on the display. A high contrast ratio is desired, resulting in richer dark colors and more distinctive color gradation.
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.
