I got a 39" Samsung LED 1080p 120hz at Wal Mart on Black Friday. I had it on layaway till last Friday and did not have the time to hook it up till a few days ago. I noticed some light gray almost white blotches on the center of my screen when anything other than a TV or movie picture is displayed. I cannot exchange the TV cause it is a model WM does not carry in stock (it can be ordered online). now onto the question at hand, I was at Sam's club today and they had a 39" Vizio LED 1080p 60hz TV on display for 12 bucks less than I paid for the Sammy (the model I got sells for 450 to 470 online I got it for 400). from what the guy at the club told me is unless you have a TV 40" or bigger you cannot really notice the difference between 120 and 60hz televisions, is he correct or full of crap? cause I have 2 options, buy the Sammy online and then when I get it take the 'defective' one back to the store, or buy the Vizio, and then return the defective Sammy.
