How to connect multiple projectors to a computer

Do you know how to connect multiple projectors to a computer? You may want to simultaneously link your computer to several projectors if you need to present to a sizable audience in a room.

It is possible to divide the photographs into two sections at opposing ends of the space, making it simple for everyone to see the image on your display. But how can multiple projectors be connected to a single computer?

In this article, we will share with you easy methods step by step to help you connect multiple projectors to a single computer.

How to connect multiple projectors to a computer?

Content that is kept on a computer is frequently presented using a projector.

This makes it possible for a big audience to view the content without having to swarm the little computer monitor.

To connect numerous projectors to one computer, though, may become required at some point.

Setting this up is simple and shouldn’t take more than a few minutes.

Step 1

A VGA splitter should be connected to the computer’s VGA port. Usually, the monitor is attached to this port (although your computer may have two VGA ports you can use). You can connect two different projectors to the PC using the splitter.

Step 2

Attach a VGA cable to each of the VGA splitter’s two splits. The projectors will be connected to these cables. You might require extraordinarily lengthy VGA connections to connect the machines, depending on how far apart they are.

Step 3

The projectors’ VGA ports should receive the free end of the VGA wires. Turn on the projectors and the computer (if they have not been turned on already). The projectors might need some time to warm up before they can start showing material.

Step 4

Select “Video Input” by pressing the projectors’ “Menu” button. The projector will show you all of the available connections that you may choose from. Move down to “VGA” (which may be labeled “Computer”) using the directional arrows, then click “OK.” The computer’s contents are now visible on the projection.

Alternative Methods

RCA Connector 

RCA connectors can be used to link a laptop to two projectors. All you need is an RCA wire that is common. First, attach one end of the RCA cable to your laptop’s “audio out” connection.

The first projector’s “audio in” port should receive the cable’s opposite end. Next, link the “video in” port on the first projector to the “video out” port on your laptop.

Last but not least, join the second projector’s “video in” port to the “video out” port on the first projector.

HDMI KVM switch 

Multiple HDMI-compatible devices can be connected to the same computer using HDMI KVM switches.

The “HDMI out” connector on your laptop must be connected to the “HDMI in” port on the KVM switch for an HDMI KVM switch to function.

Then, join the KVM switch’s “HDMI out” port to the first projector’s “HDMI in” port.

The second projector should then have its “HDMI in” port connected to the “HDMI out” port on the first projector.

Finally, attach the projectors’ power wires to an outlet.

VGA KVM switch 

You can connect numerous VGA-compatible peripherals to a single computer using VGA KVM switches.

Connect the “VGA out” connector on your laptop to the “VGA in” port on the KVM switch before using it.

Then, join the KVM switch’s “VGA out” port to the first projector’s “VGA in” port.

Connect the second projector’s VGA in port to the first projector’s VGA out port.

Connecting Multiple Projectors of the same model

You must synchronize the projectors if you plan to employ interactive features on many projectors of the same model in the same space. Connect each projector’s SYNC port to the optional remote control cable set (V12H005C28) to accomplish this.

  1. One projector’s SYNC In port and the other projector’s SYNC Out port should be connected by one end of the remote control cable. (A chain connection should be made if you are connecting three or more projectors). Set the Sync of Projectors setting to Wired in the Extended menu.
  2. (Set the Wired Sync Mode setting in the projector’s Extended menu to Mode 2 if you’re operating the projector alongside another projector in the same space that doesn’t support a cable connection. If you don’t have the optional remote control cable, go to Mode 2 in the projector’s Extended menu’s Distance of Projectors setting.)

Frequently Asked Questions

Can you use one PC and two projectors?

Different content can be displayed on various projectors by connecting two or more projectors to a single computer.

When more than one projector is attached to a computer, choose “Extend These Screens” in the Windows Display Setup to do this.

Full-screen applications will operate in this mode on one of the projectors.

Can many projectors be connected to one another?

It is possible to utilize two projectors simultaneously with a single computer, but both the computer and the projectors must be configured correctly so that the two displays combine into a single, bigger projected image.

How can I use HDMI to link my laptop to my projector?

You must first confirm that the projector and laptop are both turned on.

The HDMI cable must then be connected to the laptop’s HDMI port and the projector at the other end.

The projector should then show the laptop’s screen, and you’ll be good to go!

Projectors can they be daisy chained?

A VGA output from some projectors is meant to go to a monitor. This is buffered; in actuality, the projector includes an integrated splitter-amp. If these connectors are available, you can utilize them to daisy-chain the projectors.


We sincerely hope that this article provided you with all the knowledge necessary for How to connect multiple projectors to a computer. All you need is a splitter cable, which is actually not all that different from running a single projector.
