1080p
An HDTV resolution which corresponds to 1920 x 1080 pixels (a widescreen aspect ratio of 16:9).

3D active glasses
Wireless battery-powered glasses with LCD shutters. Synchronization information is communicated to the glasses by means of an infrared (IR) or radio
frequency (RF) emitter which is connected to the Sync Out terminal on the projector. IR or RF pulses are transmitted by the emitter to signal when the left
eye and right eye images are being displayed. The glasses incorporate a sensor which detects the emitter’s signal and synchronises the left and right eye
shutters with the projected image.
3D passive glasses
Passive glasses do not require a power source to work. Light with left-hand polarisation can pass through the left lens and light with right hand
polarisation can pass through the right-hand lens. These glasses are used in conjunction with another device which polarizes the image, such as a
ZScreen.
A
Adjust lines
A pattern applied to the image where its edge is to be blended with another image. Adjust lines are used to position the projectors in the array during the
edge blend process.
Anamorphic lens
A special lens which, when used with the TheaterScope aspect ratio, allows watching 2.35:1 content packed in a 16:9 source.
Aperture
The opening of the lens that determines the angle through which light travels to come into focus.
Aspect ratio
The proportional relationship between the width and the height of the projected image. It is represented by two numbers separated by a colon, indicating
the ratio of image width and height respectively: for example, 16:9 or 2.35:1. Not to be confused with resolution.
