Im trying to connect my macbookpro to a lg screen (lg flatron e2060)
I got that adapter http://www.apple.com/xf/shop/product/MB572Z/B/adaptateur-mini-displayport-vers-v ga pluged into the thunderblot outlet and then the vga cable directly pluged into the lg screen. I also got a bluetooth mouse and another keyboard. So when i connect all the cables an error message appear saying dsub gestion alim. I don't really know what to do ...
