Hi, recently my 54" Panny plasma quit functioning properly and, paying for a Premier protection plan for my audio/video equipment through Direct TV, they have offered to replace it with one of three choices. The display is in a master bedroom where the 54" is actually a little overwhelming for that area and I could go with something a little smaller, say 46" and up. I used to be really into high end audio/video equipment, but have been too busy to keep up with all the new trends and features that come out annually, for the last 5-10 years, so, I'm not up to date on the best way to go. I could spend another $100-200 if I need to, on top of the cash option they've allowed. The display would be mounted with 4 bolts onto an articulating wall mount. Can I get some advice on the way to go here? I lean towards Samsung but I'm open to the best unit that would be most problem free, best pic and up to date features. The three options I have are: Samsung 55" UN55J6201AFXZA; Vizio 50" E50-F2 (I told them I could actually go a little smaller if they would give me more up to date features like 4K, etc); a cash out of $475 to purchase whatever I like. What's y'alls opinion, what would you purchase? What other displays in the $475 - 675 price range would you consider?
