I just bought the top-end 15" MBP and I have a mini displayport to VGA adapter to hook it up to my TV (26" 720p resolution). The display doesn't sync perfectly with the TV and the display is good, but I feel like it could be better. Would using an HDMI adapter and cord change anything? If so, what would the differences be? Also, I think I'll be upgrading to a 37-42" 1080p HDTV in the near future, if that matters at all.
