The LG C4 OLED is the 2024 iteration of LG's popular C Series lineup and replaces the 2023 LG C3 OLED. It sits above the LG B4 OLED and below the LG G4 OLED. It uses LG's new α9 AI Processor Gen7, designed to provide better overall image processing than its predecessors. New to the C4 is the ability to game up to 144Hz, an upgrade from the maximum 120Hz on the models from the past few years. It also adds 'Filmmaker Mode' as a picture setting for Dolby Vision, designed to provide an accurate image without needing to tweak any settings. The TV uses the 2024 version of LG's webOS, and it has 40W 2.2-channel speakers built in that can be virtually upmixed to 9.1.2 using the α9 AI Sound Pro feature. It's available in six sizes: 42-inch, 48-inch, 55-inch, 65-inch, 77-inch, and 83-inch. We tested the 65-inch model.
Our Verdict
The LG C4 is impressive for mixed usage. Unfortunately, while it is bright enough to overcome glare in a bright room, it struggles to reduce the intensity of direct reflections, making glare more distracting than you'd like. However, it's well-suited for use in reference conditions like a home theater since it has vibrant colors, perfect blacks, and incredible accuracy. It's bright enough in HDR to display impactful highlights in HDR content, especially when contrasted with the TV's perfect black levels, delivering a very impactful HDR experience, although unfortunately, it's noticeably dimmer in Game Optimizer. Otherwise, the TV is a solid option for gaming, thanks to its modern gaming features, 144Hz support at 4k, and sharp motion. Finally, it's a solid option for watching content with a group of friends due to its wide viewing angle.

The LG C4 is a great choice for a home theater setup. As an OLED TV, it delivers perfect black levels without any blooming. Its HDR brightness is sufficient for highlights to stand out, especially against those perfect black levels. It reproduces vivid, lifelike colors with minimal banding, resulting in impactful HDR content. In addition, it preserves the creator's intended brightness for HDR, so you won't experience an overly bright or overly dim image. It also boasts impressive upscaling capabilities, effectively smoothing out artifacts in heavily compressed online media. Unfortunately, because of the TV's near-instantaneous response time, movies and TV shows can exhibit noticeable stutter.

The LG C4 performs reasonably well in brightly lit rooms. Its SDR brightness is sufficient to handle some glare, but it struggles with direct reflections, making it less ideal if you have wall lights, lamps, or a window facing the screen. However, blacks remain deep, and colors stay well-saturated under ambient lighting, so you don't lose much picture quality even with the lights on.

The LG C4 is a decent choice for watching sports. It's sufficiently bright in SDR to handle glare in well-lit rooms, although it struggles to mitigate reflections from direct light sources, such as lamps or windows directly opposite the screen. Thanks to its excellent screen uniformity, there's minimal dirty-screen effect in the center, and motion appears smooth and clear thanks to its fast response time and perfect transitions. It excels at upscaling both SD and HD broadcasts and streams, reducing artifacts even during heavily compressed games. Colors are vivid and accurate, ensuring team jerseys look as they should. Plus, its wide viewing angle ensures the picture remains consistent when viewed from the sides: a convenient feature for watching the game with a group of friends.

Since the LG C4 is an OLED, it has perfect black levels. Blacks are deep and inky when viewed in a dark room, with no blooming around bright highlights.
Near-infinite contrast ratio for perfect blacks with no blooming around bright highlights.
The LG C4 has impressive colors. It has solid color volume overall, so colors are vibrant and lifelike, but it struggles more with very light colors. Fortunately, this TV is amazingly accurate in both SDR and HDR, and it respects the content creator's intent without requiring calibration.
Colors are vibrant, lifelike, bright, and accurate.
The LG C4 OLED has very good motion handling when watching all types of content. The TV is completely judder-free, except if you're watching 25p content via a 60p signal, so you only notice some hiccups in motion if you're watching certain European content from an older streaming device. Furthermore, it's completely free from any micro-judder in scenes with complex motion. Transitions are perfect, so there are no artifacts around objects and people in fast-paced scenes and sports. Like any OLED, its nearly instantaneous response time causes visible stutter in scenes with slow camera movements, but this can be smoothed out using the optional motion interpolation feature.

Note:We're in the process of improving our tests related to image processing, but this score should give you a general idea of how a TV performs overall with its image processing capabilities.
The LG C4 has great image processing overall. The brightness of HDR content is very accurate, so it stays true to the content creator's intent, and color gradients are smooth with minimal banding. It does a very good job upscaling low-resolution content, so it doesn't look too soft. Its low-quality content smoothing reduces the number of artifacts you see in low-bitrate content, but it doesn't eliminate them completely.

Differences Between Sizes And Variants
We bought and tested the 65-inch LG C4 (OLED65C4); these results also apply to the 55-, 77-, and 83-inch sizes. The 42-inch and 48-inch sizes don't have LG's Brightness Booster technology, so they don't get as bright as the larger models. Note that the last three letters in the model number (PUA in this case) vary between retailers and individual regions, but there's no difference in performance. The Costco/Sam's Club variant carries the suffix 'AUA,' supports Wi-Fi 6E (the PUA variant has Wi-fi 5), and comes with store-specific perks, like extended warranties.

Popular TV Comparisons
The LG C4 OLED is an impressive TV that further cements the C Series lineup as some of the best WOLEDs on the market. Still, unless you need the 144Hz refresh rate or its other minor upgrades, you're better off getting the cheaper LG B4 OLED; it's a bit dimmer in HDR, and it doesn't have a 144Hz refresh rate, but it doesn't lose any of its HDR brightness in Game Optimizer. Also, consider the Samsung S90D OLED, as it's a bit brighter than the C4, doesn't lose any of its brightness in Game Optimizer, and is much more colorful. Unfortunately, the Samsung doesn't support Dolby Vision, so you're missing out on that by going with that model over the LGs.

The LG C4 OLED and the LG C5 OLED are very similar overall, but the C5 is noticeably brighter. Due to this extra brightness, the C5 fights more glare in a well-lit room, displays brighter highlights in HDR content, and has better color volume. One advantage the C4 has is that it supports DTS audio passthrough, making it more compatible if you don't have a receiver or soundbar with HDMI inputs.
While the two TVs are very similar, the LG C4 OLED is better than the LG B5 OLED. The C4 is brighter in HDR and SDR, handles ambient reflections better, and is capable of gaming at up to 4k @ 144Hz on all ports; the B5 is limited to 120Hz. Otherwise both TVs have the same set of features, although the B5 supports the 6Ghz Wi-Fi band, which the C4 doesn't have.
The LG C4 OLED is better than the LG B4 OLED for the most part. The C4 has better reflection handling and slightly better SDR peak brightness, so it handles a bit more glare in a bright room, and it has better low-quality content smoothing. The C4 also gets brighter in HDR in most picture modes, making highlights pop more in HDR content. However, the two TVs have very similar HDR brightness while using the Game Optimizer picture mode.
The LG C4 OLED is slightly better than the LG C3 OLED. The C4 gets brighter in HDR, so highlights pop a little bit more on it. The C4 also has slightly better PQ EOTF tracking, so it's a bit more accurate when it comes to the content creator's intent, and its better color volume delivers slightly brighter colors. If you're a PC gamer looking to take full advantage of your high-end graphics card, the C4 supports up to 144Hz versus 120Hz on the C3, so it's the better option for that. However, when viewed from an angle, the C4 has a noticeable green tint, so the C3 is the better choice for wide seating arrangements.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
