Our Verdict

LG C4 OLED

Samsung Q70D [Q70, Q72D] QLED

The LG C4 OLED is significantly better than the Samsung Q70D QLED. The LG displays perfect blacks, has better HDR brightness, and displays a wider range of colors, so it looks much better in a dark room with SDR and HDR content. The LG has a much wider viewing angle, so it's more suitable for watching TV with a group, and its better accuracy means it sticks closer to the content creator's intent. Additionally, the LG has a much quicker response time with less blur behind fast motion.
