Hi all. Having recently purchased an OLED TV, should I be concerned about showing 4:3 content? I’m referring to the vertical black bars and the potential for image retention or screen burn issues. Logically as they are black, they shouldn’t be ‘on’ so shouldn’t have an adverse effect. Wondered if there is a setting to counter any negative effects of displaying 4:3 content for long periods. I have a Sony AF9. Thanks for any advice.
