Please follow the steps below so you can try it with up to 5 displays using spacedesk Driver version 0.9.18.
1. Download the spacedesk_SetDisplayCount.zip attached below then extract the file inside.
2. You will find "spacedesk_SetDisplayCount.txt" inside, rename it to "spacedesk_SetDisplayCount.cmd", then right-click it and run as administrator.
3. Run devmgmt.msc on your primary machine and go to Display adapters -> spacedesk Graphics Adapter, then right-click -> Disable then Enable
After following the steps above, try to connect up to 5 spacedesk viewer and test it.
You can also edit the spacedesk_SetDisplayCount.txt, currently it allows up to 5 client display, you can change it to more than 5.
Please keep in mind that we limit it to 3 display connection due to performance limitation.
Connecting with up to 5 or more spacedesk viewers simultaneously, can affect the performance of each viewers connected (e.g. screen update lag may be observed) and make sure you have a powerful primary machine (latest display graphics adapter) that can handle many displays.
