Is the C5 worth the extra $100 over the C4?

Yes if your room is bright or you want anti-glare, the Gen8 processor and 40W Atmos speakers. No if you watch mostly in a dark room; the C4 has the same OLED contrast and gaming ports.

Which is better for gaming?

Both give four HDMI 2.1 ports, 120 Hz native, 0.1 ms response and VRR up to 144 Hz with G-Sync and FreeSync. The C5 adds FreeSync Premium, but the gap is small.

Which handles a bright room better?

The C5. It has a brighter evo panel and a UL-certified Glare Free coating; the C4 listing says anti-glare is not included.

Do both support Dolby Vision and Dolby Atmos?

Both support Dolby Vision, HDR10 and HLG. The C5 lists 40W 2.2-channel Dolby Atmos speakers; the C4's audio output is not specified, so a soundbar is likely.

How much have prices moved?

The C4 fell to $630.43 on October 30, 2026 and hit $870.00 on November 6. The C5 hit $939.95 on November 2 and $1,399.99 on November 7.

Neither has a published lifespan figure. The C5 is a year newer with the newer processor, so it should get webOS updates longer; OLED burn-in risk is similar on both.
