Hi, I have a new 13.5inch macbook, illuminated buttons if it helps narrow it down. I use it for djing with Serato softwear. I also use the Music Video part of it. Now, it's fine using a projector cnnected via VGA, in a different club, they use an In Focau projector, connected via cat5 into a cat5 to vga powered adaptor. If I use this, the serato control window/display on my mac expands and is too big for the screen.... Any Ideas???
