How to connect the projector to the mobile phone?

Some projectors have a USB port. You are more likely to find one on a document projector than a home theater model, although it is rare in both cases. However, if you are lucky enough to have this option, it is by far the easiest way to connect a phone to a projector. Just connect the cables to both devices, make sure the projector is set to the correct input channel, and then turn them on.


Let me talk about the wired connection first: there are two ways: one is if the smart phone supports MHL connection, then directly buy an MHL cable, connect one end to the phone, and the other end to the HDMI interface of the projector, and then select the projector The signal source is high-definition signal (HDMI interface input), which can realize the same screen of the mobile phone to the projector.
