In this face-off between the LG C4 OLED VS the LG C2, we dive into the question: Is it time to upgrade? While the C4 introduces some fresh features, the C2 hasn’t lost its luster, remaining a standout in LG’s lineup. We’ll sift through the C4’s enhancements and the enduring strengths of the C2, leading us to ponder if the newer model truly warrants the switch. Our guide aims to steer you through making an informed choice between sticking with the reliable C2 or moving on to the latest C4.

LG C4 OLED vs. LG C2: Specs and performance


Both the LG C4 OLED and C2 are stellar TVs, showcasing the best of OLED: perfect blacks, wide viewing angles, and vibrant colors.  But how does the newer C4 build upon that strong foundation?

Alpha 9 Gen 7 Processor

LG’s latest silicon is the brains of the C4. Expect these benefits:

  • Brightness Boost: While not a radical leap in peak brightness, LG promises overall image improvements and better handling of bright highlights.
  • Enhanced Upscaling: Especially for non-4K content, the C4 should make lower-resolution sources look their best.
  • AI Sound Pro: Now supporting a virtual 11.1.2 surround setup, it aims to create more immersive soundscapes from the built-in speakers.

Gaming features

Both TVs excel here, but the C4 maintains the edge:

  • HDMI 2.1: 4K at 120Hz, VRR (Variable Refresh Rate) – essential for modern consoles and PC gaming.
  • NVIDIA G-Sync & FreeSync: These technologies synchronize the TV’s refresh rate with your device for tear-free gaming.
  • Low Latency: Blazing-fast response times for the competitive edge.

What’s Missing:  Notably, the LG C4 doesn’t feature MLA (Micro Lens Array) technology, which some hoped for to achieve even higher peak brightness.

The LG C4 is a refinement of an already excellent TV.  It’s brighter overall and boasts some AI-powered enhancements for movies and gaming.  Look for in-depth reviews as they become available to see if the real-world improvement justifies the cost, especially if you can find deals on the still-great LG C2.

Performance and brightness

When it comes to performance, particularly in gaming, both TVs excel with their impeccable response times and support for a 120Hz refresh rate across all HDMI 2.1 ports. This compatibility makes them ideal for gaming on consoles like the PS5 and Xbox Series X, offering 4K gameplay at smooth frame rates. The C4 edges out slightly with a 144Hz refresh rate, catering to PC gamers seeking that extra fluidity, though current consoles won’t benefit from this increase.

In essence, while the LG C2 remains a formidable choice, the C4’s enhancements, especially for PC gaming, mark it as the superior option for those chasing the pinnacle of gaming display technology.


Design-wise, the LG C2 and C4 OLED TVs maintain a consistent aesthetic with their super slim build, emphasizing sleekness and modernity in their appearance. Both models are designed to be used with a stand for sizes above 42 inches, ensuring stability and style in one package. 

For the more compact 42-inch model, feet are included instead, providing a versatile setup option. This design choice remains uniform across both the C2 and C4 models, showcasing LG’s commitment to a cohesive and elegant design philosophy that complements any home entertainment setup.

WebOS and smart features

LG’s webOS has been consistently praised for its user-friendliness and wide app selection.  The C4 builds upon this with an updated version and potential refinements to existing features.

  • webOS Updates: Look for details on the specific webOS version the LG C4 utilizes. This can impact the interface look, navigation speed, and any new features introduced.
  • Voice Control: Both TVs will likely support Alexa, Google Assistant, and LG’s own voice control. The C4 might offer enhanced commands or tighter integration with its other smart features.
  • The Streaming Landscape: The core apps (Netflix, HBO Max, Disney+, Amazon Prime Video, etc.) won’t differ significantly between models. However, lesser-known streaming services, especially niche or region-specific ones, could be present on the newer C4.
  • Recommendations and Content Discovery: LG often uses AI to suggest shows and movies. Does the C4 improve upon this in any notable way?

Important considerations:

  • Regional Variations: App availability sometimes differs depending on your location.
  • Subscription Costs: While the TVs themselves might support various streaming services, remember that services like HBO Max and others require separate subscriptions (and fees).
  • Updates: LG can add new apps or features to older models through webOS updates. The C4’s initial advantage might diminish over time.

Unless LG radically overhauls webOS on the C4, the smart features are unlikely to be the sole reason to upgrade from a C2 owner. 

Gaming angle

Both the LG C4 and C2 are stellar gaming TVs, but the C4 aims to push the experience even further. Here’s what sets them apart:

  • Game Optimizer:  LG’s dedicated gaming dashboard is crucial.  Look for these potential C4 enhancements:
    • New Modes: Genre-specific presets (FPS, RPG, etc.) could be added.
    • Black Stabilizer: Does the C4 offer more granular control over shadow detail for spotting enemies in dark scenes?
    • Cloud Gaming Integration: If there are dedicated menus or shortcuts for cloud gaming services on the C4, this is a big deal.
  • Controller Compatibility:  Focus on the headline features:
    • Xbox & PlayStation: Official support is a given.
    • Beyond the Basics: Do they support more niche controllers, especially retro fight sticks for classic gaming enthusiasts?
  • Cloud Gaming: Power of the Cloud
    • Built-in Apps: If the LG C4 includes native apps for services like Stadia or GeForce NOW, that’s a significant differentiator.
    • Network Matters: Even with apps, a strong internet connection is crucial for the best cloud gaming experience.

Additional features for enthusiasts

  • OLED Brilliance: The self-lit pixels of OLED deliver deep blacks and instant response times – something LCD-based TVs (even with backlights) can’t match.
  • Burn-in Mitigation: LG has several technologies to reduce the risk of burn-in. Highlight these features to reassure potential buyers.
  • Filmmaker Mode: While not exclusively for gaming, accurate color reproduction can enhance immersion. Confirm its presence on both models as a point of comparison.

LG C4 OLED vs. LG C2: Price

The LG C4 OLED range keeps the same size lineup as the C2. It offers sizes starting from a compact 42-inch model to an expansive 83-inch one. With the C4’s prices now visible on LG’s official store, it’s clear that upgrading to this latest series will cost you a bit more, especially for the larger screens.

 For instance, the 55-inch C4 is priced at $1,999, showing a slight increase from the C2’s launch price for similar sizes. However, the 42-inch and 48-inch models are priced similarly between the two series. But, as the C4 becomes more available, it might be harder to find the C2 at these lower prices. If you’re eyeing the latest tech, the C4’s advancements might be worth the extra cost. 

LG C4 OLED vs. LG C2 : Conclusion

Finally, we are intrigued by the improvements LG has brought to the TV high-end market; however, this technology is not changing quite rapidly. Despite the brightness enhancements and refresh rate improvements, the LG C4 offers the same features as the C2 in general. 

Upgrading to the C4 could be tempting for tech enthusiasts eager to experience the latest advancements, but for most, the LG C2 continues to deliver exceptional value and performance. We suggest holding off on an upgrade unless you’re truly driven by a desire for the newest technology.
