How to connect an external monitor to a laptop

If you own a Windows laptop, you will use a monitor cable, like HDMI, DisplayPort, or a USB-C cable, to connect it to the external monitor. Notably, HDMI and DisplayPort have their own pros and cons, so pick the correct port for your needs.

If you’re on an Apple laptop, you will need an HDMI cable or a Thunderbolt-compatible USB-C cable. Because most monitors available today have an HDMI port, we will cover how to connect a laptop to your monitor with an HDMI cable.

Connecting a Windows laptop to an external monitor

Connect your monitor to its included power adapter. Take the other end of the power adapter and plug that into an outlet.

Connect your laptop to its charger, then plug it into an outlet.

TIPS AND TRICKS

If your laptop isn't charging while connected to the external display, it will still work. However, to ensure a fluid experience without any frame dips or freezing, you should always use your laptop plugged in if it's connected to a monitor. You can also make sure your laptop won't die unexpectedly this way.

Locate your HDMI cable. Plug one end into the monitor and the other end into your laptop.

TIPS AND TRICKS

If your monitor doesn't automatically display the contents of your laptop screen or extend it, there's a good chance you're on the wrong input. To counteract this:

  • Locate the physical Menu or Settings button on your monitor. Click it in to open up the monitor's settings menu.
  • Navigate to the Input section.
  • Select the correct input. In this case, switch to the HDMI port that your cable is plugged into.

Your laptop should now be connected to your external monitor.

Duplicate or extend your display

Moving on, you may not like the way your monitor interacts with your laptop. This is to say, the monitor may mirror your laptop screen when you want to use it as extra space. On the flip side, you may want to have the monitor mirroring your laptop so you can use it with the lid closed.

Whatever the case, you can always change this.

Open the Start menu and search for Duplicate or extend to a connected display.

When connecting your portable Macbook to an external monitor, you may run into the problem of not having the right connecting cable. Not all Macbooks have an HDMI port; however, they all have a USB-C Thunderbolt port. If you are in this situation, you will need a USB-C to HDMI adapter like this one:
