how do I connect multiple wireless displays to the same device

This simply does NOT work. Built in "Connect to Wireless Display" only allows a single connection at a time

Mine says I have to disconnect from one to search for the other. Any help?

Hello, S. Sawyer

Welcome to Microsoft Community.

The process may vary depending on your device model, operating system, and wireless display adapter. Here are some general steps and tips to help you achieve this goal:

First, make sure your device supports wireless display projection. You may contact the manufacturer to confirm this.

Next, make sure your wireless display adapters are plugged into the HDMI ports of your external monitors and powered on. You may need to change the input source of your monitors to HDMI as well.

Then, on your device, press Windows logo key + K to open the Cast menu. You should see a list of available wireless displays nearby. Select the first one you want to connect to and wait for the connection to be established.

After that, press Windows logo key + K again and select the second wireless display you want to connect to. You may see a message asking you if you want to disconnect from the first one or extend your screen. Choose Extend to use both wireless displays at the same time.

Finally, you can adjust the settings for each wireless display by going to Start > Settings > System > Display. Here you can rearrange the order of your displays, change the resolution, orientation, scaling, and other options.

Note that some devices may have a limit on how many wireless displays they can connect to at once.

Same. Is there a way to find out how many wireless displays our machines support?

I recommend to use Spacedesk https://www.spacedesk.net/, it's free, light and stable. I have been using it to cast my PC screen to three devices wirelessly: one Win11 laptop, one Win10 laptop and one Android tablet, without any delays and disconnections. Just install the server app on your PC and the client app on your external devices.

Remark: although the server driver app shows at the bottom right "Expiry of free version: Dec 31, 2024", it only means that the driver will expiry on that date and you'll need to install the new driver and keep using it as free, https://www.spacedesk.net/licensing/ "...After expiry, new Spacedesk Driver version is needed".
