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.
The most popular utilities for remote communication
- ZoneOS ZoneScreen.
- Radmin.
- TeamViewer.
- AirDisplay.
- Space desk
Such programs are divided into two types:
- Mirroring displays (Space Desk) you will simply broadcast the image from the PC screen to the laptop screen, also with their help, you can split the image on both devices (great for separate work with a separate application (Photoshop)).
- 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.
