Duet Display can no longer set my iPad to 2732x2048 resolution. I have the exact same problem with my ASUS monitor. I was once able to use PBP mode to turn the display into portrait mode and then set both sides to 1920x2160 resolution, this is also now impossible since the tools I once used can no longer configure a specific display resolution.

So now I've picked up this old cscreen: http://www.pyehouse.com/cscreen/

I've disabled system integrity protection on my MacBook Pro, but even cscreen will not allow it. cscreen will only allow me to pick from these specific options:

My iPad has the id 3f003d and it will now ONLY be set to those resolutions.

I tried the command: ./cscreen -i 3f003d -s 3f003d -x 2732 -y 2048 and no luck.

Does anyone know where I could find the system files where these very specific values are coming from?

I'm well aware of the risks, so I'll test it on an old MacBook I don't use anymore or maybe take a stab at doing in in a VMWare Fusion vm. I'm more than willing to take the risk because I hate to have this expensive piece of hardware sitting around doing nothing while I'm on the go using my laptop.
