Ultimate picture on your TV
Ever since the invention of television, people have wanted a bigger and better picture, That’s why new kind of display device like plasma TV and LCD TV have come into your life.
Samsung's revolutionary DNIe puts the ultimate picture on your screen
TM
Digital TV allowed larger screens, but only fanned the flames of demand for higher picture quality.
Samsung's dream was to meet that demand by creating a Digital Natural Image engine (DNIeTM) that could take a signal from any kind of source-not just conventional or highdefinition digital broadcasting, but even DVD, Camcorder, PC and games-and turn it into a stunning picture on any kind of screen. At last, thanks to Samsung’s 30 years of experience in TV manufacturing and an aggressive program of R&D, this ambitious dream has been fulfilled.
With Samsung, television has entered a new era. The era of DNIeTM.

The Color Optimizer also uses a new technology of color transition improvement to detect and analyze the color boundaries in detail, even in rapidly changing scenes. Together with the overall color enhancement, this helps bring natural living color to the viewer's screen.
