While there's no limit to the number of 3D glasses you can pair with BenQ projectors, keep in mind the more you use, the less stable the connection. This applies especially in these situations:
1. The 3D glasses have low battery levels
2. Distance between the 3D glasses and the projection screen is too big
3. The viewing angle is out of coverage range
4. Display brightness has decayed too much over time
