How to get two projectors to play a picture at the same time

If you need to play video in large venues, need to use two projectors, now the projector, a lot of two video interface, an input, an output, then we use a notebook with two projectors in tandem.

This principle is the same as the computer with dual display video, it is necessary to have a separate video card and have two out of the interface.

　Method/Step

1 before doing these things, we first need to determine the specifications of their own instruments performance. We can first look at the back of the projector interface.

2 to see if there are two video input ports, generally VGA in and VGA out. This is the VGA video input port and VGA video outlet.

4 we can then use a VGA cable to the two VGA ports on the projector on the VGA in, video input port, now take a VGA line, there are two VGA on the projector, and then VGA out, video output port, one end to another projector VGA in, video input port. To form a tandem on it.

5 If your projector does not have two video access ports, it will use the machine, desktop now many graphics cards are supported dual output, or more output, which is the dual graphics and so on. The first thing to look at is the video card.

6 If your projector has only one VGA input, as shown.

7 We can get two root lines on the video card, but most of the graphics cards are a VGA output, a DVI output, most of the projector is VGA input, we can use the interface to turn. Output at both ends, and then two projectors, this method not only can be two projector synchronous broadcast, also can separate screen display different screen, this depends on your computer on the video card on how to set up.

8 Remember to open the projector first, then turn on the computer. If you open the computer first, then turn on the projector, the projector did not recognize the computer, the computer restart, the projector recognized the computer.
