when i connect my philips 170c monitor to my macbook pro 13" early 2011, it does not detect the second monitor?

help! i've googled around, but none seems to solve my problem


my macbook pro is early 2011, 13", running lion.

the philips monitor is vga only, so i have a mini display port to vga adaptor and connecting it to the vga.


the screen on my mbp does turn blue, but no input is detected on the external monitor.


any advice?
