Our Verdict
LG C9 OLED
LG C1 OLED
All in all, the LG C1 OLED is a step up from the LG C9 OLED. Because most OLED panels perform similarly, you can't really go wrong with the C9, but in the years since its release, LG has improved upon certain things that are apparent with C1, despite the fact that our unit falls short in certain areas like color accuracy and brightness due to panel variation. Most notably, gaming performance is improved on the C1, including better VRR with a wider range, more BFI options, and lower input lag. Still, if you can find the C9, it still offers amazing value.
