Hello, i have a 15" macbook retina display, i am using Serato SL and ME. I am using a projector and a DJ screen but i want to add a tv, i want to use both at the same time, both with HDMI cables. How can i do this? Every time when i connect the tv to the mac, i lost the main screen i cant see the Serato SL screen, the ME screen is perfect it can be seen in the projector, the tv and the mac. What can i do to see this image only in the tv and the projector? I need the mac screen to display Serato. What am i doing wrong? Thanks for your help guys.
