Our Verdict
Samsung Q8FN/Q8/Q8F QLED 2018
LG B8 OLED
The LG B8 is better than the Samsung Q8FN for most people, unless burn-in is a concern. The LG B8 is an OLED TV with perfect blacks that delivers outstanding dark room performance. The LG is better for a room with a wide seating arrangement, as it has better viewing angles and can handle the reflections of multiple small light sources better. On the other hand, the Samsung Q8FN is more responsive to your actions due to the lower input lag, supports FreeSync VRR, and can get very bright to fight the glare of bright rooms.
