I have just joined the OLED set, but anxiety has set in. Post purchase depression? I am worried about burn in and image retention, but have no knowledge in this area. I have had the TV for 2 days, and if I'm watching Sky Sports my eyes are draw to the various logo's, instead of the match!! Also Channels with logos on Sky and free view. Also playing Blu rays that have a black band on top and below. Any guidance will be a great help.
