Having an extra screen for your work is extremely helpful.

Published onFebruary 24, 2022

We don’t give Chromebooks enough credit for the workhorses they are. When you connect your Chromebook to a monitor, you can get work done just as you would on a traditional machine with minor hiccups. Ports are sometimes confusing, so in this guide, we’ll show you how to connect a Chromebook to a monitor.

To connect your Chromebook to a monitor, you can use the HDMI port if your Chromebook has one, with an HDMI cable. If not, you will need to use a USB-C to HDMI/DisplayPort/USB-C cable, depending upon the input on your monitor. You can also connect your Chromebook to a monitor wirelessly using Chromecast.

There are a couple of ways to connect a Chromebook to a monitor or a TV. You can choose between a wired and wireless solution. Wired is generally the better option, but you may need to purchase one since it requires a compatible cable. The common display output ports you can find on a Chromebook are HDMI and USB-C, with the latter being more common.

So you’re going to need a cable that matches the display output port on your Chromebook on one end, and the display input port on your monitor on the other end. Monitors typically have HDMI, DisplayPort, or USB-C inputs now. So in most cases, you should be able to get by with an HDMI cable, a USB-C to USB-C display cable, or a USB-C to HDMI cable. You can also use a USB-C hub and a compatible cable in combination with one.

Connect using an HDMI or USB-C cable

Once you’ve determined what type of cable or hub you need and acquired it, connect the cable to your Chromebook, generally to the HDMI or USB-C port, or the hub.

Connect to a monitor using Chromecast

Another easy, albeit slightly less reliable, way to connect your Chromebook to a monitor is by using a Chromecast. It’s Google’s casting protocol, so you’ll need to have a Chromecast-enabled device — either a monitor or TV with a Chromecast device attached, or a TV that has Chromecast built-in.

Open Google Chrome and navigate to the website you want to cast. Click the three-dot menu button at the top right, and click on Cast…

Using Chrome Remote Desktop

Chrome Remote Desktop is a slightly different way to connect a Chromebook to a monitor, but a working solution nonetheless. You can use Chrome Remote Desktop to remotely connect a Chromebook to a monitor. You’ll need to have two systems for this to work — a Chromebook, and another system with Google Chrome installed and connected to the monitor.

Install Chrome Remote Desktop on the Chromebook and the other system, by clicking Add to Chrome.
