Not everyone has the desk space– never heed the finances – to afford the luxury of a dual-monitor setup. Adding a 2nd display tin can, however, revolutionize the manner yous use your PC.

Deskreen is a free Linux application that provides a clever workaround to this problem, one that makes it possible for you lot to view multiple windows at in one case beyond additional displays without spending anything. Merely put, it enables you to catechumen other devices, including phones, tablets, laptops, and fifty-fifty smart TVs, into wireless, secondary displays for your computing tasks.

Deskreen transmits your display – both X and Wayland windowing systems are supported – to your mobile devices over your local (wired or wireless) network using the WebRTC protocol.
