Deskreen is an open-source application that turns virtually any device with a web browser — such as smartphones, tablets, laptops, or smart TVs — into a second screen for your computer, using Wi-Fi or LAN connection.
It allows you to share the entire screen of your computer or just a specific window of an application. The process is simple: just open Deskreen on the PC and scan the QR Code displayed on the screen using the device that will serve as the monitor.
The software uses end-to-end encryption to protect the transmission of data and offers support for multiple devices connected simultaneously, allowing you to mirror the screen to several devices at the same time.
Other features include:
To use Deskreen as a true second screen (instead of just mirroring the image), you need to install a virtual display adapter or display dummy plug, which makes the system recognize an additional monitor.
The program's performance depends on the quality of the connection — slow or unstable Wi-Fi networks may cause delays in transmission.
Deskreen is ideal for those who want to repurpose old devices as extra monitors, make cable-free presentations, or simply mirror the computer screen to another device. It is a free, lightweight, and flexible tool, offering a practical alternative to conventional hardware solutions.
