LG C4 65" OLED TV vs LG G3 65" OLED TV

The LG G3 65" OLED TV is the clear winner. With superior peak brightness reaching 800 nits in HDR content, advanced AI Picture Pro processing, and a more premium anti-reflective screen, the G3 delivers a noticeably more impactful viewing experience that justifies its flagship positioning. While the C4 excels as a value-packed performer with lower input lag that gamers will love, the G3's overall refinement makes it the superior choice for most discerning buyers seeking the best possible picture quality.

Key Specifications Comparison

Brightness and HDR Performance: G3 Dominates

The most striking difference between these two OLED powerhouses lies in their luminance capabilities. The LG G3 65" leverages its Micro Lens Array (MLA) technology to achieve peak HDR brightness levels around 800 nits, creating highlights that pop with incredible intensity. This isn't just marketing speak – in real-world viewing of titles like Blade Runner 2049 or HDR gaming on Xbox Series X, the G3 renders specular highlights with a visceral punch that the C4 simply cannot match.

The C4, while no slouch at approximately 650 nits, falls into a more conventional OLED brightness range. This gap becomes particularly evident in brighter living rooms where ambient light can wash out the image. The G3 maintains deeper blacks and more vibrant colors even when the sun is streaming through nearby windows. If you're the type of viewer who demands reference-level HDR performance, the G3's advantage here is decisive and worth the premium.

Picture Processing and Color Accuracy

LG's AI processors have reached impressive heights, but the G3's α9 Gen 6 with AI Picture Pro gives it a noticeable edge in scene intelligence. The processor analyzes content frame-by-frame, dynamically adjusting tone mapping, color reproduction, and sharpness with greater precision than the C4's newer but less refined Gen 7 chip in certain scenarios.

In side-by-side comparisons of 4K content, the G3 consistently delivers more natural skin tones and better gradient handling in challenging scenes. Its upscaling of lower-resolution content is also superior, making older Blu-rays and streaming content look closer to native 4K. The C4 isn't bad by any stretch – its processing is excellent for the price – but the G3 simply feels more premium and refined. This is the kind of difference that enthusiasts will notice immediately while casual viewers might only sense something is "better" without knowing exactly why.

Gaming Performance: C4 Takes the Crown

While the G3 wins overall, the LG C4 65" OLED is the superior choice for gamers. Its input lag measures an astonishingly low ~5ms at 1080p/120Hz, giving it a responsiveness edge that competitive players will appreciate. The C4 also supports 144Hz refresh rates more consistently across its HDMI 2.1 ports, making it the better match for high-frame-rate PC gaming.

Both TVs feature VRR, ALLM, and full HDMI 2.1 bandwidth, along with Game Optimizer modes and cloud gaming support. However, the C4's combination of lower lag, slightly higher refresh rate support, and significantly lower price makes it the gaming champion. If your primary use case is console or PC gaming with occasional movie watching, the C4 delivers 90% of the G3's experience at a much more accessible price point.

Design, Sound, and Build Quality

The G3 is designed as a gallery-style TV meant to be mounted flush against the wall. Its ultra-slim profile and included wall mount create a picture-frame effect that looks stunning in modern homes. The C4 uses a more traditional stand design (though wall-mountable) and has a slightly thicker profile.

Audio performance favors the G3 with its more powerful 60W 4.2 channel system compared to the C4's 40W 2.2 setup. Both support Dolby Atmos and can pair seamlessly with LG soundbars, but the G3 delivers a more immersive out-of-box soundstage with clearer dialogue and deeper bass. Neither will replace a dedicated home theater system, but the G3 gets you closer to that premium experience without additional equipment.

Who Should Buy Which?

Buy the LG G3 65" OLED TV if:

• You prioritize maximum brightness and HDR impact
• You watch a lot of content in rooms with ambient light
• You want the absolute best picture quality regardless of price
• Design and gallery-style mounting are important to you
• You're willing to pay for flagship features and performance

Buy the LG C4 65" OLED TV if:

• You're looking for the best price-to-performance ratio
• Gaming is your primary use case
• You want nearly flagship performance at a mid-range price
• You have controlled lighting in your viewing environment
• You're budget conscious but still want excellent picture quality

Final Verdict

The LG G3 65" OLED TV emerges as the superior product with an 8.5/10 score compared to the C4's respectable 7.5/10. Here's why:

• Superior brightness and HDR performance – The 800 nits peak output creates a more cinematic and impactful image that enthusiasts will appreciate daily.
• Better picture processing – AI Picture Pro delivers more accurate and refined images across all content types.
• Premium build and design – The gallery-style mounting and superior anti-reflective properties make it ideal for high-end installations.
• However, the C4 offers incredible value – For many buyers, the marginal gains of the G3 don't justify the price difference, especially for gamers who benefit from the C4's lower input lag.

In the end, the G3 is the TV I'd recommend to anyone who wants the best possible OLED experience in 2024 and has the budget to match. For everyone else, the C4 represents one of the smartest purchases in the premium TV space – delivering the majority of the flagship experience without the flagship cost. Both are exceptional TVs that showcase why LG remains at the forefront of OLED technology, but the G3 is simply the better television.
