Which is better for a bright living room?

The C6H. Its Primary RGB Tandem 2.0 panel is rated up to 3.9 times brighter than LG's B series, which helps in daylight. The C5 is bright for an OLED but dimmer.

Which is better for gaming?

The C5 lists four HDMI 2.1 ports with VRR up to 144Hz, ALLM and a 0.1ms response time. The C6H lists 120Hz and four HDMI ports but does not detail 2.1 features per port.

Is the C6H worth the extra money?

If you want a 77-inch screen, the brightest C-series panel and a 26-month protection bundle, yes. If you sit close or have a smaller room, the 55-inch C5 covers the same OLED basics for less.

How big is the C6H in a room?

It is 67.4 inches wide, 1.9 inches deep and 84 lb without packaging. Measure your wall or stand before buying; the C5 is far smaller at 55 inches.

Neither listing states a panel lifespan. The C6H bundle adds 26 months of protection, which covers defects but not necessarily burn-in. Check the plan terms.

Do both support Dolby Vision and Dolby Atmos?

The C5 explicitly lists Dolby Vision and Dolby Atmos. The C6H lists HDR and Dolby Atmos FlexConnect soundbar support; confirm Dolby Vision on the spec sheet.
