Frequently Asked Questions
1. How does 3D TV work?
A 3DTV displays two separate images at slightly different angles, one for each eye. Imitating the way a person
naturally sees in the real world, a 3DTV shows a left image for the left eye, and a right image for the right eye
simultaneously. Active shutter 3D glasses let your left eye see only the view that your left eye should see, and the
right eye see only the view that your right eye should see. Your brain fuses these slightly different images and
generates a sense of depth
2. Can I use my current TV to watch 3D programming?
No. High-definition 3DTV requires different video processing capabilities and hardware than 2D sets. A 3DTV must
be able to accept higher-bandwidth signals to display 3D.
3. Can I watch things that aren’t in 3D on my 3DTV?
Yes. A 3DTV is a high-quality HDTV with additional capabilities. It shows 2D content perfectly well when it is not set
to its 3D mode.
4. What do I need to watch today’s high-definition 3DTV?
You will need a 3DTV, 3D glasses, an infrared emitter (often built into the set), a 3D video source (a 3D capable Blu-
ray player, cable/satellite box or PS3) and 3D video content.
5. Why do I need to pay for 3D glasses when I get them for free in the
theaters?
There are currently two different eyewear technologies used to view 3D – Polarized and Active Shutter. Many
theaters in the US use polarized systems, but most of today’s 3DTVs use active shutter glasses. These glasses are
more sophisticated and expensive than the passive-polarized counterparts used in theaters, due to the electronics
built into the eyewear.
6. How do active shutter glasses work?
Active shutter glasses use LCD shutters to switch between the left and right eye in sync with the image on the screen
to give you full color and full resolution in both eyes. This technology makes the glasses more expensive than
anaglyph or polarized eyewear, but the benefit is that active shutter glasses systems can deliver the highest
resolution image on today’s 3DTVs.
7. Are active shutter glasses compatible with all 3DTVs? Are they
interchangeable between different 3DTV brands?
Bit Cauldron 3D glasses work with a variety of 3DTV brands. You can take them to a friend’s house to watch on their
3DTV even it is a different brand than your 3DTV. Glasses sold by TV manufacturers generally only work with their
brand of 3DTVs.
