I have a specific need that this meets.
That said, be advised that since your device is now functioning as a monitor, and even though you may have touch enabled, your device keyboard will not pop up to allow text input via the device.
For me this is a minor issue because I’m using the device as a monitor at the distance limits of a WiFi signal. IOW, I’m far away from the computer.
I’m using this in a manner not envisioned by the developers. I’m just letting others who may have a similar need know. It’s certainly not a deal breaker, especially since I’m pushing its limits.

So much better than Duet

I moved from Duet because their software broke my computer. I had to restore it because Duet disabled my dedicated GPU and it wouldn’t work even after the app was uninstalled.

SpaceDesk is less intrusive, free, doesn’t require an account, and works better than Duet. The only issue with this app is that you lose connectivity when you trigger the Notification Center or when you receive a call (if you have hand off enabled). Minor issues that can be fixed via a software update.

In the time being I highly recommend SpaceDesk.

Display number issue

Predicament: My laptop is display #1, I then connect it to my microsoft display adapter on the tv, making that display #2, then I connect my phone using spacedesk with the intent of it becoming display #3. Instead, spacedesk becomes #2 and my tv turns into #3. I would like this issue to be fixed as it causes some problems when going fullscreen while using VLC player.

Developer Response ,

Hi toomanynicknames16098$,
you can change the position and the naming of the display in the windows display settings. Just rightclick on desktop 'Displaysettings'.
For further help don't hesitate to contact us!
