Are all 3D active shutter glasses the same, and are they cross-compatible?
• No and no. Active shutter glasses have to be synchronized to the TV to work properly and create the 3D effects. But there are many types of glasses: some are infrared (IR), some use Bluetooth or radio frequency (RF), just like some are meant for DLP displays and others just for LCDs. So make sure that when you purchase your TV and 3D kit they are designed to work with each other, and if your friends want to bring their glasses be sure to make sure they will work.
