Hi All, I have finally taken the plunge and bought a TH50PHW5B. I know absolutely NOTHING about plasma screens (except how to switch it on!!). I will only be running the DVD player and SKY Digital through it. I'm told that to get the best picture from the display, you need to alter the standard settings? Please could you guys give some advice as to what the optimal settings are? Thank you very, very much for your help, I am forever in your debt...!!!
