Are you watching some low resolution video...or are they all that way. If it is then I think it's time to return it.
Hello I bought a new TV, Panasonic Viera TX-55CX802B from John Lewis and i'm not sure if its a issue or not. I have gray color around the edges of the screen, I thought it was something to do with the back-light. I used all different backgrounds, it has shown on all apart from black. If it was an issue with Backlight Inconsistency surly it would show:
It shows nothing on black, what it could be and whats the technical term? As you can see a know very little about this and I really don't mind if you correct me
