How to Connect Chromebook to a Monitor

Most Chromebooks come with a small display and LCD displays on budget Chromebooks are just awful. By connecting your Chromebook to an external monitor, you can take advantage of the dual-display setup for increased productivity. Additional screen estate can boost productivity too. Here’s how you can connect a Chromebook to a monitor and enjoy dual display or simply mirror screen.

How to Connect Chromebook to a Monitor for Dual Display Setup

For a dual display setup, you can connect Chromebook with a monitor using a cable only. That means you cannot use your Windows/ Mac computer as a second display. Services like Duet Display or Spacedesk does allow Chromebook to act as a second display for Mac or Windows but not vice versa. Having said that, here’s how you can connect an external monitor to your Chromebook for a dual display setup.

1. First, check the ports available on both your Chromebook and the monitor. Most monitors come with an HDMI port as a standard these days. Then check if your Chromebook has an HDMI port. If available, you can use an HDMI cable to connect your Chromebook and the monitor. Most probably, you get the HDMI cable along with the monitor, so you don’t need to invest in a new cable.

2. But most Chromebooks come with only USB-C and USB-A ports. Some Chromebooks may feature mini-HDMI too. If that’s the case, you can find a suitable adaptor like USB-C to HDMI, USB-A to HDMI, or mini-HDMI to HDMI accordingly.

3. Chromebook comes with a Display link built-in unlike other traditional computers, so you don’t need to deal with drivers, etc. Once connected, your monitor should automatically detect the Chromebook and start showing the display. If not, change the input of the monitor to HDMI or the port that you have connected to the Chromebook.

4. Now, open System Settings on your Chromebook by clicking on the quick settings at the bottom right corner and then selecting the cog icon.

Connecting Chromebook to a Monitor

Chrome OS can be connected to a monitor for both dual display and mirroring your screen. While you use both wired and wireless options for mirroring screens, you have to rely on the Wired method to use it in a dual display. Third-party services like Duet Display will recognize Chrome OS like Android, so you cannot rely on them. Anyhow, not just the monitor, you can also use your TV to mirror your Chrome OS display.
