I've had a PS3 ever since 2008 when MGS4 came out. However, I have only been able to play my PS3 on a SDTV since I have been a poor college student without much extra money to spend. Now, I have graduated from college, have a high-paying job, and I am ready to upgrade to HD. I am thinking about getting a 40-inch Sony Bravia. Do I need to get an HDMI cable in order to play my PS3 games in HD? Or could I just use the red-yellow-white connectors to hook my PS3 up to my HDTV? Do Sony Bravias have LED back-lighting? A friend said that I should try to get an HDTV with that. Do Bravias dim their brightness after a certain period of time? I don't want that. Overall are Sony Bravias good HDTVs for playing PS3 games?
