Thank you oakdesign.

So MFDE + Helios.

The reason for possible network is easy.
I play on the livingroom PC - my wife kicked me out of my home office:) on the 48" monitor. It is HTPC (with enough resources for the BMS).
But I need “mobile table” to use Cougar HOTAS and so the possibility to use touchscreen on this special table is here.
Usage another PC means I will connect only 1 USB for the HOTAS and one cable to the power socket.
If touchscreen is connected to main PC the video cable must be connected too.
Thanks
