Documentation
Quote from Mark on 08/07/2026, 03:54You have documentation for /DRIVER and /VIEWER, but no documentation on /MIRROR (the one I’m most interested in.) All I want to do is mirror my laptop to another laptop with no frills. (This is also while I’m extending my laptop to a TV screen wirelessly.) Any help?

Please refer to the Documentation in the section CONFIGURATION AND SETTINGS > Windows Driver (Primary Machine) > Desktop Extension or Desktop Duplication (mirror) Settings in Display Control Panel on how to extend/duplicate your spacedesk displays.

On your home page you have /EXTENSION, /MIRROR, /VIDEO WALL, /INPUT, and /AUDIO. There’s no documentation for any of those except for /VIDEO WALL.

It’s there in the Documentation section I pointed at to you. It’s the same process as extending. Similarly, there are entries in the Documentation about Input and Audio underneath Configurations and Settings > Viewer (Secondary Device). If you want to mirror your Primary Machine’s screen with your Viewer device (laptop), please follow these steps below:
- Connect Viewer to Primary Machine
- On Primary Machine, right-click on the desktop and click on Display Settings
- Click Identify and check on your Primary Machine and your Viewer’s displays to see what number it shows.
- On the dropdown beside the Identify button, select the duplicate option that duplicates your Primary Machine’s screen to the Viewer screen. For example, if your Primary Machine’s screen is labeled as 1, and your Viewer’s screen is labeled as 2, choose the option “Duplicate desktop on 1 and 2”
If you have any more questions, please feel free to ask. Thank you.

Quote from Mark on 10/07/2026, 02:45Here’s what I want:
1. Extend my laptop to the TV screen wirelessly (already done).
2. Mirror my laptop to another laptop wirelessly (not done).
I am a DM for D&D using a TV in a tabletop setting and I have a co-DM that needs to see my screen. So, I need to do BOTH 1 & 2. In other words, I need three monitors: my laptop, TV (extended), and another laptop (mirrored).

Yes, you can do this with the steps I provided above. Just connect your co-DMs laptop to yours via spacedesk then follow the steps I provided above. You can download the spacedesk app on the Windows store so you’ll be able to connect the other laptop to yours. If you encounter any issues, please let me know. Thank you.
