Hello, In a few weeks I have to take care of the projection for a series of evening activities. I'm coordinating with a professional PA firm to handle the audio and video. I have always used a VGA connection for these sort of things because the projectors were either old or cheap or both. But this time I could use DVI if I bought the converter. My question is: will DVI be better for this, and more importantly, does it make a difference from a performance perspective. I use a first generation, rev A Macbook with 2,0 GHz core duo and recently installed 2 GB Ram. I have had to switch to synchronous mode before because the video would stutter in my keynote if I used a dual screen mode. (that was with 1 GB of RAM). Can anyone help me with these questions?
