Therefore, in order to install a laptop instead of a monitor, we will have to go other ways. There are two ways to do this:

  • Cable connection (HDMI, DVI, VGA)
  • WI-FI

How to connect a laptop screen to a computer?  Depends on what is more convenient for you. For the first two, you will need an appropriate connector and cable, for the second, a stable Internet connection.

  • We turn on both devices.
  • After loading the screen, right-click on the desktop.
  • Select the Properties / Screen Resolution tab (depending on your operating system). On macOS   System Preferences -> Screens.

How to connect a laptop and a computer using third-party programs

Can I use my laptop as a monitor just by using a utility from the Internet? – Can! You have most likely heard of a program such as TeamViewer and its counterparts, often used to establish communication between two devices. Also, products with MacOs operating systems often already have a built-in AirDisplay application, but you can install it yourself if it is not available.

Important: Air Display focuses more on dividing the display and using the laptop  as a second monitor , rather than fully broadcasting the image. This option may work for you if you have insufficient resolution, but it will not be a full replacement for it. The program also belongs to the paid category and its cost is quite high (~ 700 rubles)

The most popular utilities for remote communication

  • ZoneOS ZoneScreen.
  • Radmin.
  • TeamViewer.
  • AirDisplay.
  • Space desk

  • Utilities for remote PC control (TeamViewer) – with them you can not only broadcast the display of one device to another but also fully control the system using the second device.
