LG C6 OLED (42-inch): what the reviews say
By S. Dahani and the RealDigitalTech editorial team
The 42-inch LG C6 costs $1,399.99 in the US. Reviews of the 65-inch model praise its brightness and 165Hz gaming, but some say last year's C5 is the smarter buy.

Key figures
Launch details
LG's C6 OLED went on sale in March 2026 in four sizes in its main range: 42 inches ($1,399.99 in the US), 48 inches ($1,599.99), 55 inches ($1,999.99) and 65 inches ($2,699.99). The 77- and 83-inch versions use a different, upgraded panel and are sold as a separate model. The C6 sits below LG's flagship G6. None of the reviews we read tested the 42-inch set: all three tested the 65-inch. TechRadar says the 42- to 65-inch models share the same Tandem WOLED panel, and Tom's Guide expects similar, if not identical, performance across these sizes. The figures below therefore come from the 65-inch model.
What reviewers agree on
- Picture: TechRadar, Tom's Guide and What Hi-Fi all find the C6 brighter and richer than the C5; TechRadar measured 1,438 nits and Tom's Guide 1,355 nits in HDR.
- Gaming: all four HDMI ports are HDMI 2.1, with VRR, and PCs can run at 4K 165Hz, a first for the C-series; TechRadar and Tom's Guide measured about 9 ms of input lag.
- Processing: the Alpha 11 Gen 3 chip, usually found on LG's flagships, handles detail and motion very well.
- Sound: the built-in speakers are better than before according to What Hi-Fi, but Tom's Guide and What Hi-Fi still recommend a soundbar, and TechRadar finds the sound below the picture's level.
- Missing features: there is no HDR10+ support.
Where opinions differ
| Topic | Favourable view | Reserved view |
|---|---|---|
| Upgrade over C5 | TechRadar calls it an appreciable upgrade; What Hi-Fi sees "a new benchmark" for step-down OLEDs. | Tom's Guide calls it only an incremental improvement that most people won't notice. |
| Value | It launched at the same price as the C5. | Tom's Guide says the nearly as good C5 can be found for over $1,000 less. |
| Reflections | Tom's Guide found the screen virtually reflection-free. | TechRadar saw mirror-like reflections in bright rooms. |
| Sound | What Hi-Fi hears cleaner bass and warmer dialogue than on the C5. | Tom's Guide finds the speakers lack impact. |
Scores: 5/5 for picture, 4/5 for sound and 5/5 for features from What Hi-Fi?; Editor's Choice from TechRadar and Tom's Guide.
Verdict
The C6 is one of the best mid-range OLED TVs of 2026, and at 42 inches it is a strong choice for a bedroom, a small living room or a gaming desk. Keep in mind that no outlet we read has tested the 42-inch size itself. If you don't need 165Hz, a discounted LG C5 gives most of the same experience for less; if you want more, look at the LG G6 or our Samsung S95H analysis.
