I've been looking at TVs in the store. I'm switching to a 4K TV after using a projector for years. The Samsungs have great reviews. But, in the store, the image looks smeared and full of compression on all the Samsung displays. Clearly, this could be a crappy signal fed into the TV at Best Buy. But, how can I buy a TV when the only one I've seen in person has an image quality I don't like? I guess I'm looking for some thoughts or reassurance that the compression I see is a problem in the store, and not a real issue with the Samsung TVs. If I could believe the compression artifacting I saw is just bad in-store setup, I would be on board with the other positive aspects of these units.
