Is the C6 worth the extra over the C5?

The C6 lists at $999.99 at Beach Camera as of November 3, 2026, and no C5 price is given, so compare live prices first. If the gap is small, the C6's newer processor and 165Hz VRR are worth it. If the C5 is clearly cheaper, the picture difference is minor.

Which is better for gaming?

The C6. Both have 0.1ms response time and four HDMI 2.1 ports, but the C6 reaches 165Hz VRR versus 144Hz on the C5.

Which has better sound?

The C5 lists 40W 2.2 channel speakers. The C6 lists Dolby Atmos but no wattage. For either, a soundbar will beat the built-in speakers.

Do both support Dolby Vision and Dolby Atmos?

Yes. Both list Dolby Vision, HDR10 and HLG, plus Dolby Atmos and FILMMAKER MODE.

Both use OLED panels with similar lifespans. The C6 is a year newer, so it will get webOS updates longer. Neither has a published panel lifespan figure.

Which is better in a bright room?

Both are OLED evo with brightness boosters. The C6 adds the Alpha 11 Gen3 processor and Brightness Booster, but no peak brightness figure is given for either, so check a hands-on review.
