I just recently purchased the Panasonic VIERA® TC-P42C2 (42" 720p plasma) from Sears. I ended up getting 720p in the end because after researching the internet I was often reading it was supposedly better for gaming (PS3), which is mostly what I do with the TV. Anyways, out of the box the TV's picture seems a bit dull and dark, especially when playing video games shadows and blacks are very dark and is extremely hard to see. I'm not very experienced with TV's so basically I would like recommendations for the best calibration disc I can get. Any other tips would be awesome as well. Thanks.
