How to Split a VGA Cable

A VGA cable is also known as Video Graphics Array cable; these are extension cables that transmit video signals that will be displayed or broadcast to a monitor or projector or any display device. This is commonly used in connecting computers to their monitors. But when you need to display the same video or image to more than one display device, that’s when you will need to split the VGA cable.

As in the case of tradeshows, conference centers, hotels, airports, or even classrooms, there will be times when splitting a VGA cable is necessary to convey videos and images into a number of different separate monitors. You will find that most sources of the videos or images you want to display have only one output to connect your display devices. This is when a VGA cable splitter comes in handy.  It’s quite easy to install since it follows the typical plug and play functionality, so no need to call in the IT guy. You can install the cable yourself.

Step 1 – Check Your Equipment

Check if there are any “In” or “Out” labels on your splitter: these labels usually refer to “Input” and “Output” and serve as guides on which end to connect. If there are no labels on your cable, the end with the single plug should be connected to your computer, while the other end with multiple plugs should be connected to the display devices. It’s also advisable for you to check on your computer and look for the output for the graphic port and also check on the ports on your display devices. It’s best to familiarize yourself with all the ports to plug into before you go about with the installation.

Step 2 – Plug the Splitter to the Source

From your computer, unplug the end of the VGA cable that is connected to your monitor; this cable is where you will need to attach your VGA splitter. Connect the splitter’s end with the single plug to the VGA cable you have just unplugged; your source is now connected to the splitter.

Step 3 – Connect the Display Devices to the Splitter

Now take the end of the splitter with the multiple plugs and plug them each into the ports of your display devices. Make sure these are the ports where the VGA cables should be connected. Simply screw in the cables to the open ports where your cable should be connected. You can tighten them with a screw driver if you want to ensure that they are securely connected.

You are all set here. You have successfully attached your VGA cable splitter to your source and display devices. The video or image that you want to show on multiple display devices is now ready. There’s no need to worry about video and image quality that your multiple display devices will produce. Most VGA cable splitters have built-in enhancers to make sure that every display device delivers the best quality videos and images.
