Computer to computer
Any Mac or PC can be the screen, and you can drive it
Decky Display runs on a Mac and on a Windows PC as an app of its own. A second computer, or the laptop somebody brought to the meeting, can be a display, a viewer, or something you reach across and use. When both computers run Decky, Decky Link joins them.
Support: Use another computer as a displayA real app, on its own
Decky Display installs and runs on a Mac or a PC without Decky on the same machine. Neither asks for screen recording or control permissions. A Mac may ask once to let it find computers on your network, and Windows may ask once to let it through the firewall.
Keyboard and pointer go back
A computer showing another computer’s screen can drive it. Your keyboard and pointer reach across, so the machine in the other room is one you work on rather than one you watch.
Ask for the shape you actually want
Take the other computer’s main screen, a particular monitor of its, or a fixed size, from a Mac or a PC alike. A Mac can also give you a desktop cut to the size of one window. Choose before connecting: the screen is built to that shape and cannot be stretched afterwards.
Pick from its windows, hidden ones too
The Mac offers its window list with the hidden and minimised ones marked. "Put my mail on this screen" works without going to find the mail first: Decky brings the window back and fits it.
An Android tablet can be the source too
An Android device can share its own screen with Decky Display on a Mac, a PC or another Android device. View and control it over USB or Wi-Fi, directly or through a Room. Android screen sharing has its own feature page and guide.
A computer can sit in a Room too
Decky Display is the same app on a Mac, on Windows and on Android. So a computer is not only a second screen you drive. It can also join a Room and watch what somebody else is presenting.
