Does it make any difference if the monitor is a mac or not, to run on a mac? macbook pros use Nvidia video, but I'm not sure if it runs in a different way. Gnome?
Seems a few years back, monitors would be describes as for "PC" or "Mac", or both... Today I think you should presume a new monitor will work on either unless stated otherwise.
Just make sure you get the correct adapter. After the macbooks came out, the mini-dvi/mini-vga adapters changed. I had to return mine to get an updated mini-dvi adapter.
I know huh. The "Mac" displays use the same Samsung LCD's as the Dell displays. Apple has a nicer design and material, but its not worth 2-3x the price IMO. Also, the Dell displays aren't too bad looking.
