I've been using a mini-dvi to vga adapter to hook up my MacBook to an HDTV. The problem is the resolution becomes very, large? Safari takes up the entire screen and adjustments to the resolution on the computer just makes things either tiny or massive. I've seen a mini-dvi to video adapter which is basically just a composite video line out. Is the quality of these 2 adapters the same or would either the video adapter or vga adapter produce a better image?
