It truly is sweet...when it all works! The usb screens I'm using are the Mimo 7" mini monitors ( https://monitormega.com/ ).
They are quite neat and come on their own twist stand ( portrait/landscape), they have just the one output, a twin usb lead ( though it seems to work well just using the one usb ).
The MFD's are from Thrustmaster and again are just plug and play with a usb lead. The MFD's dont fit exactly onto the monitors, but a little black insulating tape soon covers up the overlap!
