Our Verdict
Sony X900F
LG SM8600
The Sony X900F and the LG SM8600 use different panel types, each with strengths and weaknesses. The LG SM8600 has an IPS panel, which maintains a more accurate image for wider angles off-center but doesn't look as good in a dark room. The LG also has a much lower input lag, which is great for gamers. The X900F, on the other hand, has a VA panel with a much better dark room performance and is much brighter, suitable for rooms of any brightness.
