Which is better for movies?

The C6. Dolby Vision and Brightness Booster give it more contrast headroom on HDR films. The A9 handles SDR movies well but lacks Dolby Vision.

Which is better for gaming?

The C6, on paper. It reaches 165Hz VRR with a 0.1ms response time. The A9 tops out at 144Hz VRR. Both support G-Sync, FreeSync Premium and ALLM.

Is the C6 worth stepping up to over the A9?

Yes if you watch a lot of Dolby Vision content or play fast games. The A9 is fine for everyday streaming and sports.

Both use self-lit OLED panels with similar lifespans. The C6 adds OLED Care features, but neither has a clear durability edge from owner reports.

Do either need a soundbar?

Both benefit from one. The C6 has a 2.2 channel 40W system, which is louder, but a soundbar still improves bass and dialogue.

LG OLED evo C6 55" 4K Smart TV vs LG OLED Evo AI 4K Smart TV (2025)

Both are 55-inch LG OLED evo sets with perfect blacks and four HDMI 2.1 ports, so neither is a bad pick. The C6 (A) is the newer, brighter step up: the α11 Gen3 chip, Brightness Booster, 165Hz VRR and Dolby Vision make it the stronger movie and gaming set. The C5-based A9 (B) is a solid 2025 OLED with a 120Hz panel (144Hz VRR), G-Sync and FreeSync Premium, but its listed HDR support stops at HDR10 and HLG. Buy A unless you find B at a clear step down and mainly watch SDR content.

Choose the LG C6 if you want the brightest picture, Dolby Vision, and the highest refresh rate for gaming.
Choose the LG A9 if you want proven 2025 OLED performance and mainly stream SDR shows and sports.
