Which is better for a bright living room?

The C5. Its Bright Room Ready panel and glare-free coating hold up better against windows and lamps than the C4's 250-nit panel.

Is the 65-inch C4 worth the extra money?

Only if size is your priority. You pay about $187 more for 10 extra inches but give up the newer processor, brighter panel and webOS 25.

Which is better for gaming?

The C5. Both do 120 Hz with VRR, but the C5 adds VRR up to 144 Hz for PC, a 0.1 ms response time and four full HDMI 2.1 ports.

How far should I sit from each?

About 7 to 8 feet suits the 55-inch C5 for mixed viewing. The 65-inch C4 is better at 8 to 10 feet, where 55 inches starts to feel small.

Do both support Dolby Vision and Dolby Atmos?

Yes. Both handle Dolby Vision and Dolby Atmos, and both include FILMMAKER MODE. The C5 adds a 2.2-channel 40 W speaker system.

Neither has a published lifespan advantage. Both use self-lit OLED panels, and the C5's newer panel and processor should stay current with app updates longer.
