About the equipment, I will tell you as we go through the one-by-one ways to connect. And I am here as your tutor to explain how you can connect both devices.

So let’s get into today’s tutorial on how you can connect two projectors to one laptop wire and wireless way. Step by step easy tutorial.

How to connect two projectors to one laptop with the help of a wire? 

HDMI or VGA input and output 

Go and check your projector back (Connectivity option). If you have two HDMI or VGA ports. One is input and another is output. Then feel lucky. With help of HDMI or VGA input and output port. 

You can connect your projector in a chain. 

  • Start with your laptop. Connect one HDMI or VGA cable with the laptop and another with the projector. In the laptop output port and the projector input port. 
  • Now take another HDMI or VGA cable. And connect one side of the cable with the outport (VGA or HDMI) of the projector (1st projector). 
  • Another end of the HDMI or VGA cable goes in the HDMI or VGA input port of the projector (second projector).

That’s how you can connect the two projectors in a chain. 

Using RCA connectors 

You don’t need to worry if your projector doesn’t have two input and output VGA or HDMI ports. Still, you can connect the projector in a chain. For that, you will need the RCA connectors and port. 

  • Take the first HDMI or VGA cable and connect it with your laptop and projector. 
  • For the second step, you will need the RCA connectors/S-video. Now figure out the RCA input and output port in your projector. Start connecting, start from the first projector. Connect the first RCA cable to the output port of the projector. 
  • Now move to the second projector. Here you have to connect the RCA cable to the input port.

Using VGA/HDMI/DVI splitter 

If you don’t like the above option there is another option. For that, you will need the VGA/HDMI/DVI splitter (1×2). Use according to your need. 

Here I am going to tell you how you can connect with the HDMI splitter. Other connection processes will be the same for the DVI and VGA.

  • First, connect the HDMI splitter with the laptop. And now you have two HDMI ports. By using both ports. You can project the same video on both the projector.
  • Now take the HDMI cable. And use the one port to connect with the laptop and projector.
  • Now use another HDMI port. By using the HDMI cable connected with your projector and laptop.

The same process goes for the VGA and DVI splitter.


You can also use the HDMI KVM. Which acts like one dock station. In the HDMI KVM, you will get one HDMI input and two HDMI output ports. 

  • The first connection happens between the laptop and HDMI KVM. For that use the HDMI cable. And connct the laptop and projector.
  • To add two more screens. Use the two HDMI output ports. Use them one by one to connect with your projector.
  • Now power up your HDMI KVM. By connecting with the power cable. And switch on the HDMI KVM.

Apart from the HDMI ports. Other ports are also available in the HDMI KVM. Like audio port and USB to connect with the speakers and mouse and keyboard.

What if I have to project two different videos for the two different projectors. From one laptop?

In this situation, you have to use the HDMI or VGA port of your laptop. As well as the USB port of the connection.

If you are thinking of connecting the two projectors with the help of the HDMI or DVI or VGA splitter. And want different video signals on both projectors. It will not work because the splitter port has the same video signal. 

So let’s see how you can project the two different videos from your laptop.

  • You will need the HDMI to VGA or VGA or HDMI adapter (Applicable if your projector and laptop have different ports. Else use the VGA or HDMI cable directly to connect projector and laptop). As well as USB to VGA or USB to HDMI adapter.
  • Here I am considering. We have different ports available in the projector and laptop. Take HDMI to VGA or VGA or HDMI adapter. Connect the projector and laptop with the HDMI or VGA cable.
  • Now we use the USB to VGA or USB to HDMI adapter. And also VGA or HDMI cable. And make the connection between the projector laptop.
