The light projected by the device is brighter, i.e. it has a higher ANSI lumens measurement.
The resolution represents the amount of pixels that make up the image. It is a key indicator of image quality, with higher resolutions providing sharper and more detailed images.
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.
Response time is how long it takes for a display to change the state of pixels, in order to show new content. The less time it takes to respond, the less likely it is to blur fast-changing images.
You can control the focus remotely, ensuring that the image stays crisp and clear.
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.
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.
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.
