Problem, Windows 10 identifies multiple displays without issue.
Resolume 6 Arena does not.

Test Setup 2
Primary Monitor (3840x2160) 150% Windows Scaling as Primary Monitor
Second Monitor (1680x1050) 100% Windows Scaling VGA converted from Display Port 1
Third Monitor (1920x1080) Disconnected
Display 2 now shows correctly
Test Setup 3
Primary Monitor (3840x2160) 150% Windows Scaling as Primary Monitor
Second Monitor (1680x1050) 100% Windows Scaling VGA converted from Display Port 1
Third Monitor (1920x1080) 100% Windows Scaling HDMI Output
Same output from R6Arena as Setup1
Test Setup 4
Disconnected Second Monitor And then Reconnected with R6 Open
Same as setup 1 and 3.
Test 5 disconnected both displays, plugged them into Display ports 1,2 the other way round and VGA last.
Same output from Resolume for 1,3,4.
This issue caused major problems at the weekend why trying to run 2 outputs, one to screens and one to a video stream, while running 2 displays (primary monitor and second hdmi for powerpoint.)
Resolume seems to refuse to output to a connected VGA device if there is a HDMI output also being used.
Any ideas? Never been able to get all three outputs working in R6 at once, windows has no problems.
