Our Verdict
LG C1 OLED
LG B4 OLED
The LG C1 OLED and LG B4 OLED perform similarly, but the B4 has a slight edge due to its much more accurate panel out-of-the-box and slightly better image processing. The B4 is also brighter in SDR, although the two are similar in HDR. Otherwise, the two are similar enough that you should get the cheapest one you can find.
