Our Verdict
Samsung Q7FN/Q7/Q7F QLED 2018
LG SK9000
These two TVs have different types of panels. The LG SK9000 has an IPS panel and is a better choice if you're going to watch TV from the side, as it has wider viewing angles. If you'll be sitting straight in front, the Samsung Q7FN/Q7/Q7F QLED 2018 can get brighter to fight bright room glare and can display deeper and more uniform blacks in a dark room, thanks to the higher contrast ratio and better black uniformity. The Q7FN has better gray uniformity, and it's a little better for watching sports.
