How to Fix a Chromebook that is Not Recognizing Monitor

Your Chromebook should automatically detect an external display when you connect it. If it doesn’t, temporarily connect your Chromebook to your TV or other display.

If this trick doesn’t work, resetting the connections, power cycling the monitor, changing cable, or updating the Chrome OS will fix the issue.

Relax! I will walk you through all of them step by step.

Basic Checks

Most monitors come with multiple input ports, such as HDMI and USB-C ports.

So, you must select the correct input source in your monitor’s settings. For example, if you use HDMI cable to connect your Chromebook to the monitor, select HDMI in the monitor OSD menu as the input source.

Your monitor and Chromebook might be working fine, and the issue may be with the HDMI or USB-C cable (whichever you use for connection).

If the cable is loose or faulty, it won’t transmit information from your Chromebook to the monitor.

So, make sure that all the cables are properly secured. Check both ends of the cable for any damages, and replace if you see any.

Temporary Change Display

While this might seem weird, it has worked for many users.

The workaround is to connect your Chromebook to another display, like your TV, using HDMI cable for a few seconds. Then, after that, connect it back to the original monitor again.

Reset Display Connection

To reset display connection, disconnect the monitor from your Chromebook and turn it off. Wait for three minutes before turning it back on and connecting it to your Chromebook.

Your Chromebook should be plugged in and turned on when you connect the external display.

Did it work? If it did, that’s great! If not, follow it up by restarting your Chromebook.

So here’s how to restart your Chromebook:

  1. Click on the clock in the taskbar (bottom right corner).
  2. Click on the Power icon to open Power menu.
  3. Select Power off. This will shutdown your Chromebook.
  4. Now turn it on again using the power button.

Power Cycle Monitor

Power cycling monitor is quite easy, and the same steps apply to monitors of all brands. Here’s how to do it:

  1. First, turn off your monitor.
  2. Unplug the power cord from your monitor for 1 minute.
  3. After 1 minute, plug the power cord into your monitor and turn it on.

Update Chrome OS

The possibility of a minor bug causing this display issue cannot be ignored, and that’s why I always recommend running the latest version of Chrome OS.

To update your Chromebook, follow these steps:

  1. Click on time at the bottom right corner of the taskbar and select Settings.
  2. Select About Chrome OS.
  3. Click on Check for Updates.

If any new update is available, your Chromebook will download it, and you will be asked to reboot it.
