I just tried it with both a tablet and a cell phone at the sametime. It will not work. The camera will lock on the first signal it receives from the receiver. Both devices indicate that the camera signal is being received. Only one device will connect, the other device will indicate that there is no connection to the camera. Somewhere, in the fourm, it is discussed on how to actually connect two monitors together. One receiver will be the camera controlling receiver. The other receiver can be used for audience viewing. A signal goes in and out of the first receiver and into the 2nd receiver. You will need to review the fourms to find the exact procedure. Hope this helps.
