Our Verdict
LG B9 OLED
LG C2 OLED
The LG C2 OLED is better than the older LG B9 OLED. There's not much difference in picture quality: they both display deep, uniform blacks in a dark room with no blooming around bright objects. The C2 is much brighter in HDR, so bright highlights stand out much better. The C2 also has more advanced gaming features, including variable refresh rate support to reduce screen-tearing.
