How to Use Laptop as Monitor for Macs

If you want to use your laptop as a monitor for Macs, there are 2 possibilities here - either

 1. Both devices are Macs

In this case both the main device and the laptop you wish to use as a monitor are Macs. Use Luna Display, a free app and is very easy to use.
Requirements:

  • Primary Mac needs 10.11 El Capitan or later
  • Mac to use as a monitor requires 10.8 Mountain Lion or later
  • Get the latest version of Luna Display on both computers

Connecting The 2 Devices:

  1. Download the latest Luna Display app on both devices
  2. On Primary Mac (main Mac you want to use), follow Luna Display instructions. You'll know that the connection works when the screen of second monitor that you want to use as a display changes to the settings set by your Primary Mac

If you want Retina display to work on both laptops, then both the primary device and secondary device must have Retina capabilities 

2. 2 Devices are Different Operating Systems

In this case your main device is a Mac but the laptop you want to use is not - instead, it is a Windows or Linux. If you are the reverse - Windows device wanting to connect to an Apple laptop to use as a monitor, scroll up to "If Your Primary Device is Windows but Laptop Isn't".

  1. Install 5Kplayer, a free software tool, on the laptop that you want to use as a monitor
  2. Enable airplay
  3. Your mac will recognize the laptop you want to use as a monitor as a display

As an alternative to 5Kplayer you can use LetsView which is also free.

These apps let your PC/laptop receive airplay from your Mac, allowing them to receive data from your mac. This means the devices need to be on the same internet network (or hot spot) and the responsiveness of the laptop as your monitor depends on your internet connectivity and router & host. I have no problem using my mobile hotspot for both devices (which is slower than my internet connection) and it works perfectly.



How to Use Laptop as Monitor for PS4


Can I use my laptop as a monitor for a Playstation 4? The answer is yes but using a laptop as a monitor for this purpose can be difficult. It isn’t as simple as just plugging an HDMI cable into both and playing. Unfortunately, most laptops only support outward connections for projecting their data on another screen but have no support for incoming data. This means we’re going to have to get creative.


The first option for using your laptop as a monitor requires a little preparation. You can use the PlayStation Remote Play feature to stream games from your Playstation to your Laptop and use it as a monitor in that way, but you will still need a monitor for your Playstation to use at first while you enable the remote play option and configure things. I am primarily a PC gamer and I often use this feature to stream games to my PC when I feel like playing a console exclusive.


To use this method you will first have to download the remote play app from Sony on your laptop, and this option will only work if you have a Playstation Network account, so if you don’t already have one, you will have to make one.

Once your laptop is set up, you will need to turn on your Playstation and configure it for remote play. This is done by enabling Remote Play Connection in the settings. After that, you can feel free to put your Playstation in rest mode and you no longer require a monitor for it. You can enable the ability to turn on your Playstation in the Remote Play app on your laptop and configure resolution settings from there as well.


Once you have all of your settings configured all you have to do is connect your controller through the USB port and you should be able to get started playing. As a note, you should know that this option requires a strong internet connection to keep input-lag low.

The second option requires special equipment. You can use a capture card to transmit data between your Playstation and your laptop. You just have to enable file sharing on the Playstation and connect both devices to your capture card. After everything is connected, you should be able to stream games from your Playstation to your laptop. Also, for more detailed instructions check out the dedicated 'How to Use Laptop as Monitor for PS4' post.

How to Use Laptop as Monitor for Switch

Unfortunately, you face many of the same challenges with the Nintendo Switch as you do with Playstation and Nintendo does not have an analog for Sony Remote Play. That said, you can do something similar to the capture card setup discussed in the Playstation section, but it is a little more complicated.

You will either need a USB-C to HDMI adapter, or you will have to play with the Switch in its dock. Either way, once you have a way to output to HDMI, you should connect your device to the capture card. This will enable you to transmit the data from your console to something else, in this case, your laptop.

You need to connect the capture card to your laptop, but that isn’t enough to be able to play. The data will be transmitted, but you have no way to see it. For that, you will need some kind of special software. Some capture cards come with built-in software for viewing the data that is being transmitted, which should work just fine. 

If your capture card doesn’t come with software like that then you could use streaming software like OBS to view your game. You don’t have to be recording the data to view it in the software.

How to Use Laptop as Monitor for Xbox


Microsoft's Xbox One does have its own version of the Playstation Remote Play app and, just like with that service, you will have to have a monitor for your Xbox to get things set up, but once that is done you can switch over to your laptop whenever you need to.


First things first, you have to enable connectivity with the Xbox Companion App for your Xbox. You can access this option from the guide in the preferences setting, it is called Xbox App Connectivity. Once you have set your device to allow game streaming to other devices and allowed connections from other devices to interact with your Xbox you are ready to swap over to the laptop screen.


On the laptop screen, you should open the Xbox Companion App and connect to your Xbox using the Connection panel. This will give you remote control of the console. After all of that configuration is done all you have to do is click on stream, then launch a game from the library. It should automatically start streaming the game from your Xbox to your laptop.

How to Use Laptop as Monitor for Desktop

If you are trying to use your laptop screen as the primary monitor for your PC, you have two options. You can choose to use the Miracast technology the same way you did to set up your laptop as a second monitor and simply choose “Second Screen Only” or “Duplicate” as your display option. This should work fine and doesn’t require any cables or other connection devices.

If you prefer not to use that solution, it is also possible to connect an HDMI cord from your PC to your laptop which should allow you to switch to that display.
