I'm looking to buy an LCD screen and will be hooking it up to my PS3 primarily to play games and watch movies. I came upon a reasonably priced 42" LG with 1920x1080, 30,000:1, and 5 ms response time but has a refresh rate of 60 Hz. I want the best display possible and was wondering if I should go for a similarly spec. screen but with a 100/120 Hz refresh rate. I've read some mixed opinions with some claiming that refresh rate for LCDs don't matter but the response time is more important. Would appreciate any help. thanks!
