LG C3 versus C4: a legacy-model comparison
C3 and C4 are 2023 and 2024 OLED generations. Compare the same size and full regional SKU before drawing a price, picture-quality or upgrade conclusion.
Design and placement
Both use self-emissive OLED technology. Check the exact cabinet dimensions, weight, stand footprint and wall-mount requirements.
Comparison checklist
| Item | C3 and C4: what to confirm |
|---|---|
| Processor | Compare the processor generation and supported functions in the full SKU's official data, then match them to your sources and picture settings |
| Picture brightness | Compare the same size with matching picture mode, measurement window and source rather than assuming every C4 is brighter |
| HDR support | Supported formats, compatible sources and picture modes for the exact model |
| Gaming | Native refresh, maximum input, VRR and each HDMI path separately; a pixel-response figure is not input lag |
| Smart functions | Region, firmware, language and account requirements for voice, casting and apps |
| Price and service | Current same-size quote, supply region, warranty provider and parts terms |
The linked offers are different
The product links below cover a 55-inch international-version C3 and a 42-inch local-version C4. They are not a controlled same-size comparison. Confirm each offer's actual supply and warranty; Elechid's international-TV three-year inspection and labour with parts quoted separately must not be assumed for an offer with different terms.

When an upgrade may make sense
Upgrade only if a verified feature or demonstrated picture improvement meets a need your current set does not, at an acceptable total cost. A later model year or HDMI version label alone does not establish better value.
