Our Verdict
LG C3 OLED
LG B4 OLED
The LG B4 OLED and the LG C3 OLED are very similar overall. The C3 has better low-quality content smoothing, and its viewing angle is a bit better, with less color shift as you move off-center. The C3 also gets brighter overall, so it overcomes a bit more glare while watching SDR content in a bright room, and highlights stand out a bit more in HDR content. However, the C3 is noticeably dimmer while using the Game Optimizer, whereas the B4 maintains its brightness in that mode, which makes it a bit brighter overall while using Game Optimizer.

LG C3 OLED vs LG B4 OLED: Main Discussion
What do you think of these products? Let us know below.
Looking for a personalized buying advice from the RTINGS.com experts? Insiders have direct access to buying advice on our insider forum.
Hi, we updated the firmware for the C3 to 13.40.75 including WebOS 2024 and found no noticeable improvements in Game Optimizer (or out of Game Optimizer) in HDR Real Scene Brightness when compared to the original measurements in the review. Regarding your ABL concern, we don’t expect the behavior to change either, given that the C3 already performs close to related “4” series SKUs (C4, B4): it’s very similar in full frame performance to the B4, just able to get a bit brighter in smaller slides, which is what we expect.
This, exactly. I’d be very interested in this comparison, or at least a confirmation that the ABL issues in the C3 have been addressed via firmware.
The comparison summary states that GameOptimizer mode on the C3 lowers the brightness too aggressively. LG has updated C3’s firmware multiple times and addressed other ABL related issues. Can we confirm if this still exists? Also, is there a possibility to see this issue side by side (B4 vs C3)?
