Our Verdict
Samsung QN990F 8K
LG G5 OLED
The LG G5 is much better than the Samsung QN990F 8k. The LG TV delivers much better picture quality overall. It looks better in a dark room thanks to the perfect contrast provided by its OLED panel, so there's no distracting blur around bright highlights on a dark background. The LG is also better for gaming thanks to its lower input lag and near-instantaneous response time.
