Spare desktops
A desktop with no screen behind it
A desktop with no screen behind it. Somewhere to park a build, give a headless computer a real resolution, or lay out a window at a size you do not own. It opens in a window on the computer, so you can see what is on it without going looking.
Support: Create a spare desktopYour computer treats it as a real screen
It appears in your display settings beside the screens you already have, and app windows drag onto it as they do onto any other display. On a Mac, Spaces work on it too.
Made the size of something you own
Pick the size off one of your own monitors, or off a device you have paired. A layout can be built at the exact shape it will be seen at with that device nowhere near you.
Choose which way up as you make it
Portrait or landscape is picked alongside the size, so the desktop starts the right way round.
Then share it with a whole room
Prepare a spare desktop and share it with a Room. On a Mac, a Room can carry two at once, or a spare desktop beside another display or window, and Decky Desktop can put both into one camera picture.
A clean surface to present from
Your own screen stays yours: the mail, the notifications, the half-written reply in the other window. The room sees the desktop you built for it and nothing behind it.
Several at once, at the size you need
A spare desktop is drawn by the computer itself, so its size is not limited by what a connection can carry. Make several at once. On a Mac, make one larger than any monitor you own.
