Our Verdict
Samsung Q8FN/Q8/Q8F QLED 2018
LG C8 OLED
The LG C8 is better than the Samsung Q8FN, unless the possibility of burn-in with an OLED TV concerns you. The C8 delivers perfect dark room performance with perfect blacks, as well as much wider viewing angles great for a large seating area, as well as perfect black uniformity and near-instantaneous response time. This comes at a cost, as the OLED panel is prone to temporary image retention and permanent burn-in. The Samsung Q8FN is brighter and doesn't experience image retention.
