Use multiple displays
Stream one monitor, switch mid-session, or ride the extended canvas — every screen as one spanning image.
Pick a display
Every client has a display picker. It lists the host’s monitors by name and resolution; choose one and the stream switches mid-session — no reconnect, no re-pair.
The extended canvas
The picker’s last entry is the extended canvas: every attached screen composited into a single spanning image and encoded as one stream. The cursor travels between monitors exactly as it does at the desk, mismatched resolutions included.
It costs nothing extra on the wire — it is one capture and one encoder either way. The trade-off is pixel density: three 1440p monitors side-by-side make a very wide frame, and your bitrate is now spread across all of it. For focused work on one screen, pick that screen; for “I need to see everything”, the canvas is the right tool.
With watchers connected
When several clients are on the same session, the one driving picks the display; watchers see whatever the driver negotiated, at the driver’s resolution and framerate.
