$1,1992024
Pros
- Lowest-cost entry into LG's OLED lineup with the same perfect blacks
- All four HDMI ports with VRR and ALLM at 4K@120Hz for gaming
- Dolby Vision and Dolby Atmos at an entry OLED price
- webOS 24 is one of the best smart TV interfaces available
Cons
- Only two HDMI 2.1 ports — the other two are HDMI 2.0 (limited to 4K@60Hz)
- α8 processor is noticeably weaker than the C4's α9 for upscaling and processing
- Lower peak brightness than the C4 or G4 — HDR highlights lack some punch
- No Wi-Fi 6, which limits wireless bandwidth in crowded network environments
- OLED burn-in risk remains a concern for heavy static-content users
