The display port 1.2 finally solved the problem, Thank you Oaktown. Now I'm having hard time to edit properly the f44. Resolume only see 1 Virtual, pc display and 1 screen 1280x720.
In wall designer
I select projector with native resolution 30 or 60hz?
Any step by step in this forum to set up 4 1920x1200 at 60hz so i can see 1 screen 7680 x 1200 or it's too much?
Any advice , my gig is in 12 hours
