I am a complete noob when it comes to HD, so please help me with these basic questions. My wife has a Core Duo MacBook and she desperately wants a 23" ACD. We went to the Apple Store today and were told that the monitor was HD ready but that the GMA 950 didn't support HD. She wants to watch movies on this monitor (as well as do her work), but we are both wondering this: what will she be missing with this setup? I don't know anything about HD, so I can't sort out the ramifications of an HD monitor and a non-HD graphics chip. Any and all help will be greatly appreciated--thanks in advance!
