No answer?
1. When I watch 1920x1080 pics on my 46A650 LCD TV via computer (15 pin D-sub cable) quality is fantastic on movie, standard or dynamic. In dynamic mode it is greatest but when I put the same pics in a flash and stick it to TV via USB port and start slide show quality drops a lot in dynamic mode specially for some pictures I see picture is full of dark and light pixels. Is it supposed to be this way or the local samsung person played with setting on "service menu" as soon as he entered my home without asking me and made settings worth?
He even turned on NR without asking me and when he left I realised and turned it off again. from "service menu"? When I enter service menu I am too scared to do some damaging changes?
2. Now How can I do factory reset
