LG C6 vs. LG C5: Why the 2025 model is still the smarter OLED TV model buy for me

At a glance:

• LG C5 offers up to 144Hz refresh and Dolby Vision at a lower starting price of $900.
• LG C6 upgrades to 165Hz refresh, Alpha 11 Gen 3 processor, and deeper AI integration.
• C5's older hardware means fewer AI features and more frequent discounts.

Key differences between LG C5 and C6

At first glance, LG's 2025 C5 and C6 OLED TVs look nearly identical: both support Dolby Vision HDR, Dolby Atmos audio, Nvidia G-Sync, and AMD FreeSync Premium, and both come in sizes from 42 to 83 inches. The real distinctions emerge in processing power, refresh rate ceiling, and AI capabilities.

The C5 starts at $900 and tops out at a 144Hz refresh rate, while the C6 begins at $1,400 and pushes up to 165Hz. Both share the same voice assistant ecosystem—Alexa, Apple HomeKit, and Google Assistant—but the C6's new Alpha 11 Gen 3 processor unlocks advanced AI features such as AI Picture and Sound Pro, AI Brightness Control, and native support for Microsoft Copilot and Google Gemini. The C5 will receive LG's AI concierge via firmware, but its older hardware limits the depth of AI integration.

Why the LG C5 still makes sense

For buyers who prioritize value, the C5's generation-behind status often translates into steeper discounts—sometimes as much as 50% off during major sales events. That savings can be reinvested in complementary gear like high-end sound systems, gaming consoles, or ambient lighting.

Performance-wise, the C5's 120Hz base refresh rate is already the de facto standard for 4K TVs, delivering smooth motion for sports, movies, and gaming. With VRR support, it can ramp up to 144Hz to eliminate motion blur. Dolby Vision HDR and Dolby Atmos ensure premium picture and audio quality without the AI bells and whistles that some users may find intrusive.

Why the LG C6 might be worth the premium

Power users and early adopters may lean toward the C6 for its higher 165Hz ceiling, which benefits fast-action gaming and live sports. The Alpha 11 Gen 3 chip not only boosts raw performance but also enables smarter, automatic adjustments to picture and sound based on room conditions.

AI integration is another differentiator: the C6 can run Microsoft Copilot and Google Gemini natively, allowing voice-driven tweaks to settings, content discovery, and even workflow management. For those building an AI-centric smart home, this seamless integration can be a deciding factor.

My verdict: C5 edges out C6

Despite the C6's clear hardware advantages, the C5's combination of lower price, fewer unwanted AI features, and frequent markdowns makes it the smarter buy for most shoppers. Retailers are motivated to clear C5 inventory before the next wave of models arrives, meaning patient buyers can land a premium OLED at a significant discount. Unless you need the absolute cutting edge in refresh rate and AI, the C5 delivers the best balance of performance and value.
