Best advice I can give you is to 'excercise' those pixels... Really all you need to do for that is find a nice bright colorful video and make sure it plays for longer than you play destiny until it fades away. The more use a plasma gets the more resistant it becomes to image retention. And don't worry about the 'lifetime' crap people say. The average lifetime of a plasma TV will last 25 years at 3 hours a day...
