Anyhow I am looking into getting a HDTV for my PS3. I am looking into LCD Tvs to be more specific. Anyhow this is what I know stick with 1080p and that the lower the response time the better. My question is how much would the hz effect the game play? I am guessing hz is the refresh rate. Comparing 60hz to 120hz would there be much difference? Question 2 how important is it to get a higher contrast ratio? Comparing 1000:1 and 50000:1 would there be much difference in gaming?
