I tried connecting a mbp to a Philips 23" LCD Monitor via the DVI cable. However, following the instructions menu that pop up, saying to adjust the contrast or brightness to max on the external LCD, then adjust, the graphics are just somehow rather weird in terms of color. so may i ask how do u guys do the settings on the mbp? i also notice that both the external LCD and the one on mbp both shows the similar image, how can i disable the one on mbp so that it only show on the external LCD?

back then when i was using Dell XPS, it was so much easier, all i need was to connect via HDMI, and the graphics are so nice, but using this mbp... maybe i dunno how to do the setting.... can anyone advise? thanks
