How to Use Your Laptop as a Monitor (4 Easy Ways)

In this article, we talk about what it’s like using a laptop as a monitor, why it’s beneficial, and how to set it up if that’s what you want.”

You can use a simple process to turn your monitor into an additional display device, a streaming option, or a display for chat and messaging.

Connecting A Laptop to Monitor

The process for connecting your laptop to your monitor is very simple.

First, you will need to determine which type of connection you are going to use.

You will have two options here, HDMI or VGA. For the best picture quality and highest resolution, HDMI is the preferred option.

HDMI also allows for multiple monitors to be connected at once to one laptop and can give you 5.1 surround sound when used with a home theater system.

This doesn’t mean VGA won’t work though as it will still give you a good picture in a lower resolution than HD.

Illustration of how the ‘Laptop as Monitor’ works

1) Plugin both your laptop and desktop (or TV) into power sources. 

2) Connect both laptops’ HDMI ports if they are compatible with each other. If the laptop does not have an HDMI port, connect the monitor’s VGA connector to the HDMI port instead. 

3) Turn on your laptops’ displays with their individual buttons. (If they both need to be on at the same time, you’ll have to disconnect one.) 

4) The laptop will show up in Windows as Desktop PC (or sometimes as a TV). If it already is listed as a desktop or TV, make sure it’s turned on accordingly in Settings > System > Display. 

5) All your desktop settings will be shown here. The laptop screen won’t respond to touch or be a touchscreen. 

6) You can make your laptop’s screen resolution much higher than it is, e.g. 2560 x 1080 instead of 1920 x 1080, for extra space and clarity. 

7) Similarly, you can put your desktop’s full-screen games on the laptop instead of squinting at the regular size on your desktop monitor while sitting across the room in your comfy chair.

You might also use it when you want to share your screen with somebody else or get more people involved in the computer game you’re playing. 

8) If you have a wireless keyboard, mouse, or gamepad, you can use that. Otherwise, your laptop’s trackpad will have to do. 

9) Have fun!
