The following information only relates to DLP(R) compliant IR emitters and 3-D shutter glasses sold by DDD and IO-Displays and its partners and affiliates. The effective range of the IR emitter is directional. At a 90 degree angle, directly in front of emitter, the maximum range the 3D shutter glasses can synchronise with the TV is 10m (34ft). At 40 degrees either side of the front-on position the maximum viewing distance reduces to 4m (14ft) and at an oblique angle of 70 degrees from the front-on position the viewing distance reduces to 2m (7ft).
