Digital Projection INSIGHT 4K Dual LED & Quad Series

Appendix E: Glossary Of Terms

1080p
An HDTV resolution which corresponds to 1920 x 1080
vertical resolution of UHD.
2K
A resolution which corresponds to 2048 x 1080
of 4K, therefore a 4K projector can display 2K images by pixel and line doubling, without distorting the geometry of the image.
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.
4K
A resolution which corresponds to 4096 x 2160
resolution of 2K.
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
edge blend
during the process.
