I'm tempted to try out 4K TVs and from what I've researched the Samsung performs pretty well in its price range in terms of color, image etc. But what concerns me is that there aren't a lot of 4K contents available yet so if I buy a 4K TV, I will most likely use it for 1080P or blue ray movies. In that case, will I just be better off buying a 1080P TV like Sony KDL55W800B? Is the Sony a top tier 1080P TV? How does it compare to the low-end Samsung 4K? By the way, as I'm placing the TV in my bedroom, with a viewing distance of approximately 5.5 feet, will a 55 inches TV be too large? Please help me out of this dilemma guys. Any advice is appreciated!
