I've been in the same boat. I have yet to find Dual Monitor mode. If anyone could point me in the right direction, that would be much appreciated. I have two y-cables and they only work as an extension with the male end that forks and the female end. The other male connector doesn't do anything with how I have it set up. Final question, is the starter kit actually required if I'm running from a commander pro? I had 4x450mm connected to one channel but the light cut out about halfway through the third with 4x450mm strips selected. Right now I have 2x450mm connected to each channel but that prevents me from setting everything up the way I had planned. Thanks in advance!
