The pens are difficult to use or slow to respond when I use them with multiple projectors of the same model in the same room. What should I do?

• See below.

  Connecting Multiple Projectors of the Same Model

  If you use the interactive features of multiple projectors of the same model in the same room, you need to synchronize the projectors. To do this, connect the optional remote control cable set (V12H005C28) to the SYNC port on each projector.
  1. Connect one end of the remote control cable to the SYNC In port on one projector, and connect the other end to the SYNC Out port on the other projector.
     
     

     Note: If you are connecting three or more projectors, connect the projectors in a chain as shown.
     

  2. In the Extended menu, set the Sync of Projectors setting to Wired.

     Note: If you are using the projector in the same room as another projector that does not support cable connection, set the Wired Sync Mode setting to Mode 2 in the projector's Extended menu. If you do not have the optional remote control cable, set the Distance of Projectors setting in the projector's Extended menu to Mode 2.
