HI Karl.
Nice video, nice tune.
In the future just paste the full url here and forum auto-publish the video 🙂
At this days all computers, desktop or laptops support dual monitor.
I think is better connect to your current pc a external monitor, this is very cheap faster, and you can build some case for transport etc.
Asus Vt229h
In this way you no need WIFI and run Chameleon on the same computer your DAW, extending the desktop, one run Chameleon other your DAW.
Asus Vt229h is perfect size, good price.
Your title said, Android, chameleon not run on Android OS............go with the solution I suggest.
For sure there is a lot of models of touch monitors, I suggest that duet is cheap and i super tested that.
About WIFI, there is some guides here in the forum.
