I experience exactly the same problems with this App. I made a virtual 1920x1080 monitor and moved MFCDs and CDU exactly as described at instructions http://www.lumatek.sk
Game responds on the buttons, but instead of image from displays android App shows blured image of CDU for each display.
BTW, the default size values you recommend in info at server application are not available - when I try to put size of MFCDs to 450 server app says that I cannot put it more than 400. And when you change size of MFCDs you should change them in .lua. So, I put 400 and here is my .lua:
I tried to play with firewalls, made sure that NAT on my router is working, tried to change the ports, but nothing helps yet.
Hope you will find some time to check this, I would definitely like this thing working, and I really appreciate your efforts to make it happen!
