Hi

I have 42pfl7655h/12 and it looks like non of these picutre format works.
As I understood these features supposed to zoom vertically so that black margin at the top and bottom of the picture will be removed.
I don't see nothing like this happens, and I don't see any difference between the two.

what do I do wrong? am I misunderstanding something?

Thanks

btw: TV software is updated
