Use a Laptop as a Monitor - How to Use Your Laptop as a Second Monitor

Use a Laptop as a Monitor - How to Use Your Laptop as a Second Monitor for Your Computer

If you have a spare laptop sitting around, did you know you could use it as a second monitor for another computer such as a desktop or another laptop computer?

Your laptop screen is a perfectly good screen, but how do you get the video output from your other computer (desktop or notebook) into your laptop? Unlike display monitors, the vast majority of laptops do not have video inputs. They only output video. So, how can you possibly get the output from another computer to display on your laptop computer screen? This video will show you how to use your spare laptop and the wireless display capability built into Windows 8 and Windows 10 so your laptop can function as a second screen for your other computer.

Save the cost of buying a second monitor by using a spare laptop instead. This video demonstrates exactly how to do that, and it requires no additional hardware or software.

Thank you. Now my partly-broken old laptop has some meaningful existence.

You have the same energy as my teachers at the tech college I attended. You are calm, speak clearly, and slowly. I appreciate it greatly. I may know how to use the adobe programs but I don't understand computers all that well.

This man goes into so much detail its phenomenal

This is sick. I turned my convertible tablet with pen into a duplicate of my primary monitor and now I can highlight and write in one note using a pen instead of a mouse. There is a bit of a lag, and its a little redundant looking down at the smaller screen and finding the part I want to highlight again, but it is still really cool. I have a second monitor as an extension to the left as well.

Worked Flawlessly.

For those who don't find Projecting to this PC option in the Dialog, Go to Settings - System - Projecting to this PC. If it's greyed out, click the above install feature button and add Wireless display, I had to this as well.

I was able to extend my display onto the secondary laptop - THANK YOU! So helpful when I travel, as I generally have two laptops with me. Problem: The sound moved to the secondary. All I had to do was go to Settings, Sound, choose the primary computer for output. Easy fix! Now to try it with a presentation!!

It's very rare to meet someone that explains very clearly and in extreme detail without becoming stupid. But in my opinion you are such a person. Impressive!

this has to be the most bland and basic, yet most entertaining video I've seen from a informative tech channel

[janniksemperowitsch]

Happy to know that.
I always took a HDMI-cable and plugged it into a HDMI-to-USB Converter (Elgato Camlink but cheaper) and let OBS run in preview-mode on the Laptop, so it shows what the Main PC wants to show on its third Monitor.

It works because the HDMI-to-USB Converter is identified as a monitor by the Main rig.

for people doesn't see Projecting to this pc option here is the solution

type ''Projecting Settings'' in settings and go into it, then you will see a message that says : ''add ''wireless display'' optional feature to mirror to this computer'' click on the blue text under it and click add button. after that type Wireless Screen and install that.

that should do it :)

I lost it when he said you can ask the kid down your street to set up your wifi 😂😂😂

But honestly - THANK YOU. I wanted to check as I will be getting another laptop and want to connect my current one (a laptop + tablet). I wanted to check if its input will work both ways.

[natsu_cathelper]

Connect to wireless didn't pop up for me but it's still a good video.

[ironpanv]

Great tutorial! It's very detailed and it tells you everything you need to know so you can change everything based off of your preferences. Keep up the good work!

[viosim]
