What is an IR emitter?
An IR emitter is sold with wireless 3-D shutter glasses and essentially provides a method of transmitting the 3-D sync signal to the glasses by sending out an infra-red signal. The IR emitter should be connected to the VESA compliant 3D Sync Out port on the side of the TV. In special circumstances, an IR emitter may not be required for 3D DLP products even if it is stated as required in your 3D DLP product manual. A specific example is that an IR emitter is NOT REQUIRED to use DLP Link 3D shutterglasses such as the Xpand X102 with any 3D DLP HDTV or Projector product.
