Hi, I recently bought a new 24" monitor for my pc, on which I already had two 19" monitors connected. The 24" replaced one of the 19" leaving me one unused monitor. I therefore bought a mini-DVI to DVI cable, and it works like a charm, though there is one thing that is bugging me. I simply cannot make the external screen act as the main screen. Fx if I want to play a movie in VLC media player and I drag VLC media player to the external screen and press "Full screen" it makes it full screen on my MacBook and not the external. I would much rather watch movies on the 19" instead of my 13.3" MacBook. By the way the monitor is in the kitchen, 'cause I like to watch movies while cooking and eating. Is there a way to fix this problem so I can watch movies in full screen on the external monitor?
