General info

1.lamp life

20000h

This shows the lifespan of the light source. Beamers need to have their lamps (light source) replaced every now and then.
2.audible noise

23dB

Audible noise is the noise that a device produces while in operation. Reduced audible noise improves quality.
3.power consumption in standby mode

0.5W

The power consumption in standby mode, also called energy-saving mode, measures the amount of power the device consumes when shut down but still plugged in.
4.weight

7kg

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
5.width

345mm

The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
6.volume

24682.85cm³

Volume is the quantity of three-dimensional space enclosed by the product's chassis or, in simpler terms, the space the product occupies.

Projection quality

1.resolution

1920 x 1080px

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.
2.ANSI lumens

1000cd/m²

The light projected by the device is brighter, i.e. it has a higher ANSI lumens measurement.
3.maximum projection size

300"

The maximum size of image that a device can project without compromising quality.
4.zoom ratio

1.9:1

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.
5.has lens shift
