Which has the better picture, the C5 or the B5?

The C5. Its OLED evo panel and Alpha 9 Gen8 processor give higher brightness and more refined processing than the B5's standard OLED panel and Alpha 8 chip.

Is the C5 worth the extra over the B5?

If you watch in a bright room or want the largest, brightest picture, yes. If budget or room size is the limit, the B5 keeps the same OLED blacks and 120Hz gaming features for $899.99 at Amazon as of November 3, 2026.

Which is better for gaming?

Both are strong. Each has a 120Hz native panel, four HDMI 2.1 ports and VRR, and the B5 adds G-Sync and FreeSync Premium. The C5 adds QMS and VRR up to 144Hz for PC.

How much bigger is the C5's screen?

The C5 is 55.2 inches and the B5 is 48 inches, about 7 inches more diagonally. That is a noticeably larger picture at the same viewing distance.

Do both support Dolby Vision and Dolby Atmos?

Yes. Both list Dolby Vision and Dolby Atmos, and both include FILMMAKER MODE. The C5 has the stronger built-in speaker system at 40W and 2.2 channels.

Neither maker publishes a lifespan figure for these 2025 models. Both are OLED panels with the same burn-in risk, so viewing habits matter more than the model.
