Full screen and resize

Full screen

Choose Full screen at the top of the session's page. To leave, press Esc.

The button is missing where the browser you are using cannot do full screen, such as on an iPhone.

Resize

The desktop follows the size of the screen box. Make your window larger or smaller, or go full screen, and the desktop takes the new size after a short pause. Chromium's window stays maximised, so it follows too.

The desktop is at most 2560 by 1600. In a larger box the picture is scaled up to fit.

The size changes only when a viewer asks. With no page open, the desktop keeps the size it last had, which is also the size an agent sees.
