Our Verdict
LG B9 OLED
Sony X950H
The LG B9 OLED is a significantly better TV than the Sony X950H. Due to OLED's emissive technology, the LG has an infinite contrast ratio that can produce perfect blacks, without any blooming caused by local dimming. Viewing angles are better on the LG, and so are black and gray uniformity. Also, the LG has near-instantaneous response time, much lower input lag, and it supports VRR. However, the Sony can get much brighter to deliver a better HDR experience, and it's much more color accurate out of the box.
