Our Verdict
Samsung Q8C/Q8 QLED 2017
Samsung Q7CN/Q7C QLED 2018
The Samsung Q7CN is somewhat better than the Samsung Q8C. The Q7CN has better black uniformity that matters when you watch dark scenes in a dark room. The Q7CN can also overcome the glare of a bright room better since it can get significantly brighter. Finally, the Q7CN is a better choice for playing video games as it has lower input lag and supports the FreeSync variable refresh rate.
