It doesn't seem like the developers of that piece of software are active anymore. They have not replied in the thread.
Now the A5 Pro has a root available. Would this make it possible to somehow monitor and/or control the signals sent to the device/OS for a full screen refresh? Would that information then be useful for creating a driver?
I have no idea how these drivers are written and I'm not a developer or coder myself, but would be willing to run some tests if it's something that I could manage
