Our Verdict
Samsung Q9FN/Q9/Q9F QLED 2018
Sony A8F OLED
The Sony A8F is a bit better than the Samsung Q9FN, unless the possibility of burn-in with the OLED panel is a concern for you. The A8F delivers a perfect dark room experience, with an infinite contrast ratio and perfect black uniformity. The A8F has wider viewing angles and a faster response time, good for fast moving objects. The Samsung Q9FN is a bit better for gaming, as it has much less input lag and some new gaming features, such as automatic low latency mode and supports a variable refresh rate. The Q9FN is also much brighter and better able to overcome glare in a bright room.
