Our Verdict
LG C8 OLED
Samsung Q6FN/Q6/Q6F QLED 2018
The LG C8 is significantly better than the Samsung Q6FN. The LG C8 is an OLED TV with perfect blacks which has remarkable picture quality that looks amazing in a dark room. The LG C8 has better reflection handling and wider viewing angles, and is more suitable for a wide room with many light sources. On the other hand, the VA panel of the Samsung Q6FN doesn't have a permanent burn-in risk, like the OLEDs, and the TV incorporates the FreeSync variable refresh rate and a low input lag, which is great you're a fan of video games.
