Our Verdict
Samsung Q70/Q70R QLED
LG CX OLED
The LG CX OLED is much better than the Samsung Q70R. The LG can individually turn off its pixels, so it can produce perfect blacks. It also has much wider viewing angles, much better reflection handling, and it supports Dolby Vision. The Samsung can get much brighter, supports HDR10+, and doesn't have the risk of permanent burn-in.
