Our Verdict
Sony X850F
LG SM8600
The Sony X850F and the LG SM8600 both have very similar performance. The Sony is more suitable for a brighter room as it can get brighter in SDR and can also display HDR content with bright highlights. The LG has a slightly better dark room performance with a higher contrast ratio and a local dimming feature. The SM8600 also has lower input lag, which is great for gamers, and a better black frame insertion implementation that can make the motion crisper.
