I saw a 4k tv the other day at Best Buy that was showing a city sky line of New York city. It looked really clear and detailed. It blew away what we get from anything we call HD today. The price on the other hand was out of sight. Besides there is NOTHING in 4k today and there won't be anything but 1080i or 1080p to show on it , so I see no reason to upgrade. PRICE alone is the deciding factor for most people today. So I don't see this 4k selling any better than 3-d did. I only bought a 3-D tv after Conns store sold it at a reduced price, back last year in January. They had practically nothing but 3-D tvs that they "were giving away for practically free", is what the salesman said. I needed a new tv so I bought it. Of course I knew nothing about the fan in the back of the tv panel, that has to remain dust free or the tv turns itself off. Costed another repairman call to find out you can spray a can of compressed air in the back and it cleans it right out.
