HDTV opened your eyes, but at least one expert says you’re going to notice a real difference when you look at ultra HD. 

Consumer Electronics Association spokesman Jim Barry says its screen uses four times the pixels.

“Four or more times sharper than our current HD, and also has deeper color saturation,” Barry says.  “A lot of technical aspects of it make it a much more spectacular picture.”

It's also more energy-efficient.  The 78-inch bendable screen televisions went on sale last week in South Korea.  They are costly.

"It's something like a 78-inch screen,” he says, “and the price is something like 70-thousand dollars."
