Hi, Very soon, I will getting an iMac (20") and I am planning later on to connect it to one of those HTIB (home theater in a box) through the optical output and to a LCD tv. What are the main things I should look for in a LCD/plasma tv to be able to connect it to the mac? Is there a optimun screen size or resolution? (I am planning on a 30" screen) What is the best connection? What ports should I look for in the TV? Thanks.
