When presenting content from a computer, a projector is frequently employed. At business meetings and presentations, projectors are sometimes utilised to allow several employees or spectators to see slide displays, computer demonstrations, or other materials. This allows a big audience to view the content without crowding around a single computer monitor. However, a single projector may not always be enough to cover the entire area where you want the projected material to appear so, you’d need to know how to connect two projectors to one computer.
If you are doing a presentation in a large hall where two screens are required for audience or want to combine two projectors. In any case, you’ll need to know how to control two projectors from a single source device. Two projectors can be connected to the same computer and used simultaneously, but both the computer and the projectors must be properly configured so that the two screens merge into a single, bigger projected image.

Hardware is Required to Connect two Projectors to One Computer.
To do this, you need to invest in certain hardware. You will need a splitter cable or a certain adaptor to get started. The model of your projector and your laptop have a major impact. You’ll need a splitter cable or adapter for this, depending on your laptop and projector model. Connect the single-side cable to your laptop’s Video Output port. Connect one cable from the splitter/adapter to the Video Input port of your projector, then repeat with the second projector.
Why the Splitter?
Well, because your laptop normally only has a single output connection for your display and you want to operate two projections, you have to turn it into two. This is the location of the splitter cable when you’re using 2 projectors for one image.
You just need a splitter cable or adaptor to plug your laptop into two projectors. These goods are cheap and easy to handle. Make sure you have the length right so that the wire works from the laptop to the projectors at the desired distance.
There may be two video graphics ports on some computers, especially on desktops, so that you can plug in several projectors at the time. If you don’t have a computer with dual VGA connections, you will probably have to buy a device known as a VGA splitter to split the signal and enable it to play via both projectors. This weakens the picture, although the difference is hardly visible as long as you only once divide this picture. If you are utilizing a 2 Vs 1 projector, the video/image quality should be more or less equal but may begin to degrade if more than two projectors are added to the network.
Check your Laptop Output Port.
Don’t worry if you have a recent laptop, which only supports VGA input with HDMI output. You only have to buy an HDMI to VGA cable. Usually, most common computers have an HDMI output port. Some earlier versions also feature the VGA port, thus instead you may have to deal with a VGA cable. Before you can go out and buy a cable, you need to check what type of Port is installed on your laptop.Check the input port on the projector.
The next step is to check your projector’s input port. At the rear of the projector, the Video Input port should be situated. Check your type. Check the kind. Although HDMI and DVI are also widespread, most typical projectors link VGA cords. Some projectors are equipped with the relatively new DisplayPort.
Your projectors must be provided with VGA input if your laptop supports the VGA output. If not, you will first need to set up an adaptor. You have to have the equivalent output head on the output side of the laptop connector, while the side of the adapter has the same port as the projector. Then you need merely to link the one-side cable on your laptop’s output port and you’re good at doing it. The output side of your laptop should have an Output Head (VGA, HDMI or DVI) with the appropriate Input Head and the adaptor side should have double cables.
The cable length must be measured in advance, as discussed. Let’s presume you have the HDMI input and output port for both your laptop and your projector. An HDMI splitter with a single HDMI output head and two HDMI input heads are required for purchasing. The same is the case with VGA or DVI ports.
Connect it all.
Connect the cable in a splitter to each of the two splits. The cords will be connected to the projectors. Just connect the one cable and the two cables to each projector input port to the laptop’s output port. Make sure that you switch both the laptop and the projectors on when you connect. You’ll have your power cables on your projectors so you plug them in and turn them on.
⦁ To select “Check-in video”
⦁ Click on the “Menu” button of the projectors.
⦁ All possible connections you can select are displayed with the projector.
⦁ To move to the required selection port (may be referred to as “Computer”), use the browser arrows,
⦁ Then select “OK.” On the projection presently, the content of the computer is visible.
Configure the PC.
Place the two projectors that you are using in front of the computer on a strong, stable platform. Make sure that the projectors are connected and activated, so they can warm up if they want. This guarantees the PC that the projectors are recognized as peripheral devices. Allow the two projectors to fully power in advance.
To display on external viewing devices, press the button on your laptop. Usually, this is a button with a monitor image.
If the picture is not on the projectors;
⦁ Please click “Start”
⦁ Go to “Panel Control”
⦁ Go to “Sound and Hardware”
⦁ Click on “Projector Connection”
⦁ To show on the laptop and projectors, click ‘Duplicate’
⦁ Duplicate Click
⦁ To only display on the projectors, click “Projector only”
Common Problems in Multi-Projector Setup.
When you’re using 2 projectors for one image, several problems may develop. Learn how to correct them is vital and when you’re on the big stage might save you from embarrassment and trouble.
Projector Heats Issues.
Projection devices naturally get warm when used, but projectors might overheat when cleaning, maintaining, or improving air circulation is essential. Use the following ways to address the overheating if you turn off or display a warning message at random:
⦁ Clear the projection area.
⦁ Make sure the projector vents are not blocked.
⦁ Clean any dust from the filter and dust.
This is a pretty common scenario in which the picture is a little distorted and numerous reasons may exist – one of the reasons for the links. You can try to change it and see if it works to correct that. You can modify color and display settings and optimize the light.
Display Toggle Issues.
All you need to do is press the Windows and P key if the laptop defaults to an extended mode which is usual for most laptops. You can then select the corresponding display setting.
You should have your built-in speaker system for your projector. This is appropriate for small meetings or rooms where there are not many participants. You should only utilize the projector from a distance and turn the volume up. Your laptop thinks it’s attached to a TV and responds accordingly when connected to a projector. The audio signal is therefore transmitted via the HDMI cable.
A Cord is Too Short.
You may need an extra cord if your laptop is too distant from the projector. You can connect the extension to your projector cable and then to your laptop through an HDMI or VGA extension connection.
Remote Control Not Working.
You want the projector to operate from afar, but it doesn’t appear or doesn’t work as efficiently as before on the remote. The main reason is that battery power is finished. Distance is the second common reason for remote failure. Could it be that you are too distant from the projection sensor?
We hope this post will provide you with all the required knowledge for your system of multi-projectors. If you have the correct connectors, you should face no difficulty in using 2 projectors for one image. It’s not so different, it’s a splitter cable which you need from running one projector. Just ensure that if you have no photographs on your screen, you’ve selected the correct source.
A splitter cable is easy to use and an adapter can provide you with greater versatility. If you wish to add even more projectors or display devices, an adapter with multiple output options, like VGA, HDMI and DVI should help you.
