Our Verdict
Samsung Q9FN/Q9/Q9F QLED 2018
LG C8 OLED
The LG C8 OLED TV is better than the Samsung Q9FN for most people, unless you watch a lot of static content and are concerned about burn-in. The LG C8 has an infinite contrast ratio and no need for a local dimming feature, as well as an ultra-wide viewing angle, but it can experience permanent burn-in. The C8 has a nearly instantaneous response time, although this can bother some people as 24p content can appear to stutter. The Samsung Q9FN has much better color volume and is much brighter and better capable of overcoming glare in a bright room.
