Ok .. i got the demo over here .. I got my bm us3d tb capture card.. As you state here in the resolume forum that the blackmagic works fine.. even better with the new 4.0.1 release.. Well as soon i plug in my bm i cant start resolume.. i deleted the prefs the xml.. everything .. nope.. REstore windows.. yeah .. i tried .. wont work..
As soon i unplugg the bm .. it starts .. So .. your pruduct is far from ok with blackmagics products as you state in here. Or did i miss something ? now ..
*edit. Ok you can't run extended desktop with blackmagic us3d and resolume .. thats the issues. turn it off res starts.. but it's usless anyway .. as i dont got any more ouputs. i hate apple now .. never a mac again ..
