How To Connect a Monitor To a Laptop Using HDMI (And Use Both Screens) 🖥️ 2021

A laptop's biggest limitation is its screen size. It can't be big or it will increase it's weight, diminishing its portability value. 

So what we do is add an external monitor in our workspace. But how do we connect them?

First let's talk about what you need:

  • Laptop
  • Monitor
  • HDMI cable
This is just the basics. You will obviously need to connect the laptop and monitor to a power source, but these kind of cables usually come with your devices.

Which HDMI cable?

There are different kinds of HDMI cables on the market. They mostly differ in the resolution they can output but that's not the only difference.

If you don't have a HDMI cable already, be careful when you buy a new one.

This is the HDMI cable you need to connect your monitor to your laptop:

Note this is a "male to male" connection.

This is NOT the cable you need:

Note this is a "female to male" connection. They are mostly used as extensions or adapters. If you need more details, check this article:

Types of HDMI Cables

Ok now we can start the step by step tutorial.

Step 1: Power on your laptop and monitor

You have to connect your power cable to an electric source.

It's ok to have a blank or dark screen in your monitor. Just make sure it is on.

It usually displays some sort of message like "no signal" or at least a stand by light.

Step 2: Connect the HDMI cable

In this step you will connect the HDMI cable to your monitor and to the laptop.

If you don't have a cable yet, check this article:

Both sides are the same and it doesn't matter which side you use.



You can choose any HDMI port. If your monitor has multiple ports like the one above may need to select it. In some monitors it is just like selecting a channel in a TV.

The tips above should cover 99% of the cases. If you are still not getting your laptop's image on your monitor, make sure:

  • The power is on. On both devices.
  • You have the correct HDMI cable (Link above). Lower resolution cables will not work on higher resolution devices.

Step 3: Configure the display

The standard configuration is mirroring. It means you will get the same image in your laptop screen and in your monitor.

If you just want a bigger screen then that's ok. You do not need to do anything else.

But if you want to be able to use both screens you will need to configure it.

In windows it goes like this:

  1. Click Start" button.
  2. Select "Control Panel".
  3. Type "display".
  4. Click "Connect to an external display".
  5. Click "Extend these displays".
  6. Make sure your mouse movement matches the screen. Drag and drop the screens if not.


I understand sometimes you just need to see people connect a monitor to a laptop using HDMI and configure it to use both screens on windows 10 (Reported to work on windows 11). Turn on captions if you need it:

My Recommendation

There are many low-quality models in the market. They all promise great performance but fail to deliver it.

If you want to skip poor quality HDMI cables, pick one of the two below. They are all type A (male to male):

HDMI 2.1 (8k)

4k and lower resolution
