I had a few minutes to kill this morning and went into Best Buy to check out their TVs, For the first time, I looked at some 4K TVs. They looked incredible. They had a 65" Samsung LCD that showed a 4K demo loop. Had images of a city at night, desert scenes, etc... . The image blew me away. Looked like the image was painted on the screen. I couldn't see any individual dots from any distance. Even from 8 feet back, the image looked fantastic. It was way better looking than any of the 1080p TVs on display. The image quality absolutely blew away my Panasonic ST50. After reading how many state you can't tell a difference between 4k and 2K, I wasn't expecting much. But, there is clearly a huge difference. Sadly, they didn't have any OLED TVs.
