Frequently Asked Questions
3-D Shutter Glasses
What are 3-D shutter glasses?
3-D shutter glasses or LC (liquid crystal) shutter glasses provide a means of alternatively blocking the display from the left and right eyes and are essential to the 3-D Game mode.
3-D shutter glasses come in two forms: wired and wireless. Wired glasses are connected directly to the "3D Sync Out" port on the side of the TV. Wireless glasses require the use of an IR emitter (see below).

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.
What is the effective transmission zone of the IR emitter?
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).
Where can I buy compatible 3-D shutter glasses?
Compatible 3-D shutter glasses can be purchased from our on-line store.
Are any shutter glasses compatible with the Samsung 3-D DLP(R) HDTVs?
Not all wireless 3-D shutter glasses are compatible with the Samsung 3-D DLP(R) HDTV as they interfere with the infra-red signals used by the remote control.
How can I tell if my shutter glasses are working?
Due to the speed with which the glasses shutter (60 times/sec per eye) it is not possible to see the shuttering process with the naked eye. However, the glasses will appear darker when they are actively shuttering.
A simple way to determine if the glasses are working is to remove the 3-D sync signal. For wired glasses this simply involves removing the connector from the "3D Sync Out" port. For wireless glasses a simple method is to obscure the IR receiver in the center of the glasses. Once the 3-D sync signal is removed the glasses should transmit more light than when when the 3-D sync signal is present.
How long do the batteries last on the wireless 3-D shutter glasses?
The battery life for the wireless 3-D shutter glasses is approximately 80 hours
What batteries do the glasses use and where can I buy more batteries?
The replacement batteries for the 3-D shutter glasses are 3V CR2032. Two batteries are required for each pair of glasses.
How do I turn the glasses on and off?
The glasses turn on and off automatically using a sensor switch located in the temple of the glasses. When the glasses are put on, the switch closes and the glasses will activate in the presence of an IR emitter. When the glasses are removed, the switch opens and the glasses turn off.
