I've bought the Matrox analogue dual head to go, and not the dp edition. I have bought a mini display port to vga adaptor to run the dual head to go or another monitor output. I will be having a look at seeing if it all works ok. I dont have a full licence for ME (just yet) as you can understand the video side of dj'ing is an expensive route to take. I want to make sure it works for what i need it to do before spending vast amounts of money. I do know of people using the dual head to go, and ME in which they feed the 2 x digital outputs into 'scan converters' which allows the digital signal to be changed to a composite signal, as they are using the pioneer av mixer. They also have the setup so they can have the left deck as a individual screen and the same with the right deck. This can be set in both ME and VSL. I just needed to go 'bigger' with the MBP screen been on the smaller side. The way im looking to do it, is to have ME setup on the MPB, serato on my 19" monitor, then the ME (or VSL) output on the 3rd screen. I still may have to get a scan converter to allow the signal from the Dual Head to Go (VGA) to composite to the bars system. I hope that make sense?????
