I have just purchased the above plasma and I'm connecting it to my HTPC via a DVI cable. I will be using the HTPC for Nebula TV, Theatertek DVD and high def films. What is the optimum set up on both the PC resolution and the plasma options? I am a total newbie so would prefer a simple step by step guide. Would I need different settings for NTSC and PAL DVD's. Would these apply to High Def films? Would this set up achieve 1:1 pixel mapping? Any other tips in the Picture settings? For example, do I alter the plasma contrast or Theatertek's contrast? Finally is it worth having the screen calibrated?(What does this mean?) I live in Grimsby, could you recommend anyone local? Thanks in advance.
