After a long time not playing the M-2000 and several DCS updates I realised that it did not export the radar to my second monitor.
I reinserted the files from Greekbull into the correct folders and everything work except the radar. Not exporting the radar view is only true in in cockpit view. When I switch to any other view besides the cockpit view, I get the radar exported to my 2nd screen.
Appreciate if some one could help ...
