Our Verdict
Sony X850G
LG SM9000
The LG SM9000 is a better TV for most uses than the Sony X850G. The LG has local dimming, more accurate colors out-of-the-box, a wider color gamut, and an easier-to-use smart interface. On the other hand, the Sony looks better-built, can get much brighter, has much better gray uniformity (resulting in less dirty screen effect), and better reflection handling.
