Overview
The LG C4 OLED is a 55-inch 4K OLED TV that builds on the success of the C3 with a brighter panel (thanks to LG's Brightness Booster Max) and improved processing via the α9 AI Processor Gen7. It supports Dolby Vision, Dolby Atmos, and all four HDMI 2.1 ports for 4K/120Hz gaming, VRR, and ALLM. The C4 runs webOS 24 with a streamlined UI and supports Alexa, Google Assistant, and Apple AirPlay.
This TV is aimed at enthusiasts who prioritize picture quality above all else. Its self-emissive OLED pixels deliver perfect blacks and infinite contrast, making it ideal for dark-room viewing. Gamers benefit from low input lag (9.2ms at 4K/120Hz as measured by RTINGS) and NVIDIA G-Sync/AMD FreeSync compatibility. The C4 also has a wide color gamut covering 98% DCI-P3, excellent for HDR content.
Available on Amazon and other major retailers, the 55-inch C4 currently sells for around $1,500. While the newer C5 offers a slightly brighter panel and a more advanced processor, the C4's price has dropped significantly since launch, making it a strong value proposition. It's also a popular choice for those who want OLED quality without the premium of LG's G-series with its gallery design.
Pros
The LG C4 OLED delivers outstanding picture quality that makes movies and games come alive. Here are the key strengths that have made it a favorite among enthusiasts.
Exceptional Black Levels and Contrast
The LG C4's OLED panel produces perfect blacks by turning off individual pixels. This creates an infinite contrast ratio that no LCD TV can match. In dark scenes, like a starfield in space or a shadowy room in a thriller, there's no blooming or halo around bright objects. According to RTINGS, the C4's black uniformity is flawless, which directly translates to an immersive viewing experience. This is most noticeable in a dim or dark room, where the TV's true potential shines. For movie lovers, this means you see details in shadows that get crushed on most LED TVs.
Incredible Gaming Performance with 4K 120Hz
With four HDMI 2.1 ports, the C4 supports 4K at 120Hz with VRR and ALLM. Input lag is a mere 9.2ms at 1080p/120Hz and 9.8ms at 4K/60Hz (RTINGS), making it responsive for competitive gaming. It also supports NVIDIA G-Sync and AMD FreeSync Premium, so PC gamers get a tear-free experience. The 120Hz refresh rate ensures smooth motion in fast-paced games like Call of Duty or racing sims. The C4 is one of the most gaming-friendly OLEDs on the market, especially since it offers Dolby Vision at 60Hz (though not at 120Hz).
Outstanding HDR Performance
The C4 is capable of high brightness for an OLED, reaching around 800-900 nits in a 10% window on our reference (LG spec claims up to 1100 nits with Brightness Booster Max). This is enough to make HDR highlights pop, like sunlight glinting off metal or explosions in action movies. Its wide color gamut (over 98% DCI-P3) ensures vibrant, accurate colors. According to manufacturer specs, the C4 covers 100% of the sRGB and 98% DCI-P3, and third-party tests from Wirecutter confirmed excellent color accuracy out of the box. HDR content on platforms like Netflix or 4K Blu-rays looks spectacular.
Excellent Processing and Upscaling
The α9 AI Processor Gen7 does a remarkable job upscaling low-resolution content to 4K. Standard-definition cable or YouTube videos look cleaner than on many competitors, with reduced noise and sharpness. It also handles motion well with its TruMotion feature (though purists may prefer to turn it off). The AI Picture Pro feature analyzes the content and adjusts settings automatically, often improving the image without making it unnatural. This processor also enables Dolby Vision IQ, which adjusts the picture based on room lighting.
Sleek Design and Build Quality
The C4 has a slim profile (less than 2 inches deep) and a sturdy, low-reflection screen. The bezels are minimal, giving it a modern look that blends into any room. The stand is a central pedestal that can accommodate a soundbar. The TV feels premium in hand, with a metal backplate. It's also relatively lightweight for its size, making wall-mounting easier.
Cons
Despite its many strengths, the LG C4 OLED has notable weaknesses that may be deal-breakers for some. Here's where it falls short.
Risk of Burn-In with Static Content
As with all OLEDs, the C4 is susceptible to permanent burn-in from static elements like news channel tickers, game HUDs, or desktop taskbars. While LG has improved panel durability with technologies like the Brightness Booster Max and pixel refresher, the risk remains higher than with LCD TVs. RTINGS's long-term test showed that OLEDs can develop burn-in after several years of heavy use with static content. This is a concern for those who watch news channels or play the same game for hours daily. Workarounds include lowering brightness, using screen shift, and avoiding prolonged static images.
Lower Peak Brightness Compared to High-End QLEDs
While the C4 is bright for an OLED, it still falls short of the best mini-LED QLEDs like the Samsung QN90C or Sony X95L, which can exceed 2000 nits. In a very bright room with direct sunlight, the C4's image can appear dimmer than those rivals. Specular highlights might not punch as hard in well-lit conditions. This is less of an issue in a dedicated theater room but worth noting if the TV will be in a bright living room. The difference is about 30-40% in peak brightness according to third-party measurements.
Limited Viewing Angle for Color Accuracy (Wide Angle is Good but Not Perfect)
OLEDs are known for wide viewing angles, but the C4's panel shows some color shift when viewed from extreme angles (beyond 45 degrees). At off-angles, whites can take on a slight greenish tint and colors can desaturate slightly. While still far better than most LCDs, it's not as consistent as the best QD-OLEDs from Samsung or Sony. For a TV that will be watched directly in front, this is fine, but for a wide seating area, it may be noticeable.
No Dolby Vision at 120Hz
As of 2026, the C4 cannot support Dolby Vision gaming at 120Hz (it caps at 60Hz for Dolby Vision). This is a hardware limitation of the MediaTek chipset used in many LG OLEDs. If you want both Dolby Vision and 120Hz simultaneously, you'll need to look at Sony's X90L or X93L (though those are not OLED). The workaround is to use HDR10 or HLG at 120Hz, or stick to 60Hz for Dolby Vision titles.
webOS Can Be Slow and Ad-Riddled
webOS 24 is a significant improvement over previous versions, but it still can feel sluggish when loading certain apps or switching inputs. The home screen includes advertisements and recommended content, which some users find intrusive. The remote (LG Magic Remote) has a pointer feature that some love and others find gimmicky. Compared to Google TV on Sony or TCL, webOS has fewer customizable options and app third-party app support (e.g., no official Amazon Photos app).
👍 Who It's For
The LG C4 OLED is perfect for movie enthusiasts who primarily watch in a dim room. The perfect blacks and infinite contrast make film noir, sci-fi, and any dark scene look stunning. It's also an excellent choice for console gamers who own an Xbox Series X or PS5, as the four HDMI 2.1 ports ensure you can connect multiple consoles and a soundbar without sacrificing features. PC gamers will appreciate the G-Sync and FreeSync support.
Another group that will love the C4 is those who value picture quality above all else and don't mind the risk of burn-in (or use the TV for mixed content). If you switch between movies, TV shows, gaming, and streaming, the risk is minimal. The C4 is also a great pick for those on a budget who want OLED but can't afford the G-series or Sony's high-end models.
Finally, if you have a dedicated home theater room with controlled lighting, the C4's brightness is more than sufficient, and you'll fully enjoy its cinematic strengths.
👎 Who Should Avoid
If your TV room is very bright with lots of windows, the C4's lower peak brightness may leave you disappointed. In a sunlit living room, the image can look washed out compared to a bright QLED. In that case, consider a mini-LED like the TCL QM8 or Samsung QN90C.
Those who watch a lot of cable news, sports channels with static tickers, or play the same game with a persistent HUD for hours daily should be cautious about burn-in. While modern OLEDs are better, the risk is not zero. An LCD TV would be a safer bet for such use.
Budget-conscious buyers who want a large screen might find the 55-inch C4 too small for their space, and the price per inch is higher than mini-LED alternatives. If you need a 75-inch TV for the same price, look at the TCL Q7 or Hisense U8K.
Finally, if you want the absolute best for HDR brightness or need Dolby Vision at 120Hz for gaming, the C4 falls short. The Samsung S95C or Sony A95L QD-OLED offer better brightness and color volume, though at a higher price.

Alternatives to Consider
| Product | Choose LG C4 OLED (55-inch) if... | Choose the alternative if... |
|---|---|---|
| LG C5 OLED$300 more expensive | You want the best possible brightness and future-proofing for the same size | You can find the C4 at a significant discount (e.g., $300+ less) and don't need the subtle brightness upgrade |
| Samsung S90D QD-OLED$200 more expensive | You prioritize Dolby Vision support and perfect blacks with a lower risk of burn-in | You want higher peak brightness and better color volume in a bright room, and you don't mind missing Dolby Vision |
| Sony A80L OLED$100 more expensive | You want better motion processing and upscaling, plus a more natural picture out of the box | You need four HDMI 2.1 ports for multiple gaming consoles and prefer LG's gaming-friendly features |
| TCL QM8 Mini-LED$300 less expensive | You're willing to sacrifice some contrast for a much brighter, larger screen at a lower price | Perfect blacks and wide viewing angles are more important to you than peak brightness |
If you're considering the C4, the main alternatives are the LG C5 (newer model), the Samsung S90D (QD-OLED), and the Sony A80L (OLED). The C5 offers a slightly brighter panel and an updated processor, but it's more expensive. The Samsung S90D uses QD-OLED technology, which provides higher peak brightness and better color volume, making it a strong choice for bright rooms, but it lacks Dolby Vision. The Sony A80L has excellent processing and upscaling, plus a superior sound system, but it has only two HDMI 2.1 ports and is typically pricier.
For LCD fans, the TCL QM8 (mini-LED) offers brightness levels exceeding 2000 nits at a lower price, making it ideal for bright rooms, though blacks are not as perfect as OLED. The Hisense U8N is another high-brightness option with great contrast. Both are cheaper and available in larger sizes.
Is it worth the price?
At approximately $1,500, the LG C4 OLED is very good value for a premium OLED in 2026, especially since it's a previous-year model that still holds up well. It's worth it for home theater enthusiasts and gamers who want HDMI 2.1 features without paying $2,000+ for a C5 or QD-OLED. However, if you need the latest brightness improvements or want Dolby Vision at 120Hz, the C5 might be a better long-term investment. For bright-room viewers, the TCL QM8 at $1,100 offers better brightness and size options.
📝 Bottom Line
The LG C4 OLED remains one of the best TVs for dedicated home theater use in 2026. Its strengths—perfect blacks, excellent gaming features, and strong HDR performance—make it a top choice for movie lovers and gamers who primarily watch in dim rooms. However, it's not perfect: burn-in risk and lower brightness compared to high-end QLEDs are real drawbacks that will matter to some buyers.
For those who can live with those cons, the C4 offers a compelling package that rivals or exceeds many current-generation TVs. The value is particularly strong now that the C5 is out, as the C4 has dropped in price while retaining 95% of the experience. If you can get the 55-inch C4 for under $1,500, it's a steal.
Skip the C4 if you need a TV for a bright living room, if you're concerned about burn-in from static content, or if you must have the latest brightness levels. In those cases, consider the TCL QM8 for brightness or the LG C5 for a modest upgrade. But for the average enthusiast who wants the quintessential OLED experience without breaking the bank, the C4 still delivers.
