Our Verdict
Samsung Q7CN/Q7C QLED 2018
LG SK9500
The Samsung Q7CN is a bit better than the LG SK9500 unless you'll be watching from the side, in which case the LG is a better choice due to the wider viewing angles. When sitting directly in front, the Samsung Q7CN has deeper blacks in a dark room due to the higher native contrast ratio and better black uniformity. The Q7CN also has better gray uniformity and is better at handling bright room reflections. Finally, the Samsung Q7CN is a better choice for HDR gaming due to the lower input lag and support for the FreeSync variable refresh rate.
