Which has the better picture, the C5 or the B6?

The C5. Its OLED evo panel is brighter and its Alpha 9 Gen8 processor is a tier above the B6's Alpha 8 Gen3. Both use self-lit OLED pixels for perfect black.

Is the C5 worth it over the B6?

Yes at current prices. The C5 is $969.99 at Walmart versus $1,299.99 for the B6 at LG as of November 6, 2026, and it has the better panel and processor.

Which is better for gaming?

The C5. It reaches 144Hz VRR for PC gaming and has four HDMI 2.1 ports with ALLM and QMS. The B6 tops out at 120Hz, though both have 0.1ms response time and G-Sync plus FreeSync Premium.

Does the B6 have any feature the C5 lacks?

Yes. The B6 runs webOS 26 with Google Gemini and Microsoft Copilot built in. The C5 runs webOS 25.

What sizes does each come in?

The B6 is listed in 48, 55, 65, 77 and 83 inches. The C5 listing here covers only the 55-inch model.

Neither maker publishes an OLED lifespan figure for these sets. Both are OLED with the same self-lit pixel technology, so treat longevity as comparable and check the warranty at each store.

LG C5 OLED evo 4K Smart TV (2025) vs LG OLED AI B6 4K Smart TV

Buy the LG C5 for most people. It has the brighter evo panel, the Alpha 9 Gen8 processor, four full HDMI 2.1 ports with 144Hz VRR for PC gaming, and a much larger review base at 4.8 out of 5. At $969.99 at Walmart as of November 6, 2026, the C5 is also $330 cheaper than the B6's $1,299.99 at LG. The B6 only makes sense if you want the newer webOS 26 with Gemini and Copilot, or a size the C5 listing does not cover.

Today the LG C5 OLED evo 4K Smart TV (2025) costs $302.99 less at its best price.
