Sony X900F vs LG SK9000

The LG SK9000 is a better choice if you're going to watch TV from the side, as it has better viewing angles. The Sony X900F is better for directly in front seating arrangements. The LG SK9000 has better input lag and better black frame insertion (BFI), which make it slightly better for gaming and can be attractive to gamers. The Sony X900F has better contrast and local dimming, and much better black uniformity so it can display deeper blacks that improve picture quality in a dark room and make it a much better TV for movies. The Sony also has a faster response time and better gray uniformity that make it a marginally better choice for sports fans.
