Our Verdict
LG C3 OLED
Samsung CU7000/CU7000D
The LG C3 OLED is better than the Samsung CU7000/CU7000D in every way. The C3 has a much better picture quality due to its perfect contrast and the ability to display much deeper blacks, so it’s the better choice for a dark room. The C3 is significantly better for gaming due to its much faster response time, HDMI 2.1 bandwidth, and 4k @ 120Hz support. The C3 is also better for watching shows or sports as a group because of its much wider viewing angle. Finally, HDR looks significantly better on the C3 thanks to its wider color gamut, better color volume, and higher HDR peak brightness, so colors are more vibrant and lifelike, and highlights pop a lot more than on the CU7000.
