I'm pretty to new to all this hackintosh stuff but got it managed to install OSX Maverics successfully on my XPS.
I read in the Tutorial I used that DisplayPort should work. I have 2 FullHD Displays connected (HDMI, Displayport) but only the HDMI one is detected. Meaning that internal Notebook Display + HDMI works flawlessly. What do I have to do to get the 2 Second Display online (and deactivate the internal one, like it is under Windows). I've read a lot through different Forums but most the answers are confusing me . So hopefully someone can give me hint.
