Record one monitor while keeping working notes on another
With two monitors, “record my screen” is ambiguous. Build a simple display map before recording: which screen is the audience allowed to see, where are your notes, and which one will the recorder actually capture? A second monitor is useful separation only when the saved video confirms it.
Label the displays by what they show
Put a harmless large label on each display: “Audience” on the demonstration and “Notes” on the private workspace. Identify physical position, not just a number that may change after docking. Close real private notes while setting up this test.
Check whether the displays are extended or mirrored. If they show the same desktop, moving notes to the other screen may not separate them at all. Start with an extended workspace and a clean demonstration window before opening confidential prompts.
Follow the recorder’s actual selection model
Loom’s multiple-monitor page currently says its desktop app and extension do not record two monitors at once or switch monitors mid-recording. For the documented Mac desktop workflow, moving its toolbar to the chosen display determines capture. Those are Loom instructions, not universal shortcuts.
The inspected Reel Mac implementation records a display; it does not establish an arbitrary third-party window picker or simultaneous multi-monitor recording. Use the current Reel controls and a saved sample to establish the selected display. Do not infer selection merely from where your camera image appears.
Create a boundary test before the full take
Start a disposable recording containing the two harmless labels. Move a small test window from the notes display to the audience display, then back. Stop and play the file. You should see only the intended interval and display.
Now rehearse the actions that can cross that boundary: opening a file, dragging an attachment, using a system dialog and changing a browser window. A file chooser can appear on a different monitor from its parent window. Keep private names out of these tests.
Treat the camera overlay separately
A camera preview on another monitor is not proof that it is excluded. Reel’s Mac floating camera can be composited into the exported picture independently of the main app window’s visibility. Disable the camera when you do not want it; verify the export rather than hiding a window off to the side.
When a presenter is wanted, choose a place that does not cover menus or the final result. Check the recorded image, not just the live desktop. The capture boundary and the camera composition are two different checks.
Repeat after a display change
Docking, undocking, reconnecting an adapter or changing the display arrangement can invalidate your old map. Repeat the labelled sample before a sensitive session. A previous successful recording does not certify the current display selection.
For a longer demonstration, keep the necessary source windows on the audience display throughout. If you need a different monitor, stop and create a separate take using a verified selection, rather than assuming the recorder will follow your pointer.
Can I record both monitors into one Reel video?
This guide does not establish that capability. It describes verifying a single recorded display. Choose a recorder with documented multi-display composition if that is the requirement.
Will moving the face camera to another screen keep it out?
Not reliably in Reel’s Mac workflow. Turn the camera off and verify the saved sample when exclusion is required.
