I'm looking to buy an LCD TV to watch HD programming and play next gen console games (xbox 360, ps3). However, I have some questions. 1. What is the contrast ratio (ie, 400:1)? 2. Is a 8ms response time better or 16ms? 3. What is the difference between HDTV and HDTV ready? 4. I want razor sharp gaming and crisp tv programming. What other aspects of a LCD TV should I look into?
