Which is better for a bright living room?

Neither has a listed anti-glare coating, and OLED panels are glossy, so both struggle with direct sun. The C6's Dolby Vision helps it tone-map bright HDR content, but a shaded wall or curtains matter more than the model.

Which is better for gaming?

The C6. It lists 165Hz VRR, while the C4 tops out at 120 Hz with G-Sync VRR certification. Both have four HDMI ports, so console and PC hookups are equally easy.

Is the C6 worth it over the C4?

If a 55-inch screen fits your room, yes: it is about $234 cheaper as of November 4, 2026 and adds Dolby Vision, Dolby Atmos and 165Hz VRR. Pay the extra for the C4 only if you need 65 inches.

How much bigger is the C4?

Ten inches diagonally, 65 versus 55. That is roughly 40% more screen area, which is noticeable at couch distance of 8 feet or more.

Neither maker publishes a lifespan figure. OLED pixels dim with use and static logos can cause burn-in on both; one C4 owner reported burn-in. The C4's webOS Re:New program promises 5 years of software updates.

Do both support 4K at 120Hz?

Yes. Both are 4K OLEDs with 120 Hz panels and four HDMI ports, and the C6 goes further with 165Hz VRR.
