Our Verdict
Sony X900F
LG SK8000
The LG SK8000 has an IPS panel with better viewing angles and thus is more suitable for a large room. The Sony X900F is a better choice if you're sitting directly in front. The LG SK8000 has slightly better input lag and a better black frame insertion (BFI) feature to clear up blur that gamers will appreciate. On the other hand, the Sony X900F has better local dimming and better black uniformity and contrast that allow it to display deeper blacks, making it something you will appreciate in a dark room while watching movies. The Sony can also get brighter and has better HDR performance.
