Do DisplayPort Splitters Really Work?


There are a lot of products on the market these days, and frankly, a lot of them just don’t work. Lots of companies make disingenuous promises about what their cream, cable, or car can do. 

Are DisplayPort splitters another cash-grab that doesn’t fulfill their prophecy? Or are they actually an essential part of anyone’s media setup?

Here’s everything you need to know about DisplayPort splitters, along with a few of our favorite suggestions. 

What Do DisplayPort Splitters Do?

A DisplayPort splitter lets us mirror one image transmitted through the cable to two monitors, effectively ‘splitting’ the display. For example, if you want to enjoy a multi-screen setup (like having the same video play on two projectors for a large event) a DisplayPort splitter will help you set everything up. 

Normally, a DisplayPort splitter will have one connector which you plug into the device of the screen you want to be duplicated, and two ports for you to plug the other monitors into. While DisplayPort cables may look very similar to HDMI cables, they are not compatible. 

DisplayPort technology is renowned for its high video resolution and frames per second. While recent HDMI cables can transmit relatively high-quality video and audio, it isn’t nearly as reliable as DisplayPort technology. 

A cable splitter should not be confused with a cable switch. A DisplayPort or HDMI switch acts like an extension cord, allowing you to plug more cables into one device. It cannot duplicate images, so make sure you don’t buy a switch instead of a splitter on accident. 

A DisplayPort splitter also cannot extend a monitor. This is another common misconception. Monitors hooked into a DisplayPort splitter will simply mirror each other. 

Do DisplayPort Splitters Really Work?

Yes! DisplayPort Splitters really work! 

What’s more is that they are very easy to set up and will last a long time. 

There are a few things you need to look out for though. 

HDMI or DisplayPort?

Check if you’re actually using DisplayPort connectors. HDMI connectors look almost identical, so you need to make sure you aren’t getting the two mixed up. DisplayPort ports and connectors are more angular and simple than their HDMI counterparts. 

The best indicator is how easily the connector plugs in. if you find yourself forcing things, you might have gotten the two mixed up. 

Is Your DisplayPort Cable Working?

DisplayPort technology is not immune to aging. If you’ve had the same DisplayPort cable for several years, it might not work as well as it once did. Like HDMI connectors, DisplayPort connectors contain several pins that hook into the port. If one (or many) of those pins is damaged, you may not enjoy the same high-quality viewing experience you once did. 

Cheap DisplayPort cables also age quicker. We recommend investing in a DisplayPort cable that will last several years instead of buying a cheap one from the corner shop that you’ll have to repurchase in a month or so. 

How to Use a DisplayPort Splitter?

Using a DisplayPort splitter is very simple. However, there are a few things you will need beforehand. 

Make sure you have two DisplayPort cables (with male connectors on both ends) on hand. You will also need to make sure all your devices are DisplayPort-compatible. If they aren’t, you will need to sort the appropriate adapters out. 

Plug the DisplayPort splitter connector into the original device. This could be a video game console, laptop, computer, or anything else holding video and audio data you want to send to other devices. 

Afterward, hook the two (or three!) DisplayPort cables into the splitter and your monitors. 

And that’s it! You’ve officially duplicated video and audio using a DisplayPort splitter!
