LG C5 OLED TV review: already on course to be one of 2025’s best TVs

LG C5 OLED TV review: Two minute review

The LG C5 is a feature-packed, mid-range OLED TV that continues the LG C-series legacy of offering real bang for your buck. Launching at $2,699.99 / £2,699.99 / AU$4,299, the 65-inch model I tested is priced exactly the same as its predecessor, the LG C4, one of the best TVs of 2024.

The LG C5 comes with a host of new AI features and an Alpha 9 Gen 8 AI Processor that leads to a modest picture brightness boost over its predecessor. LG’s C-series continues to lead the way when it comes to features in a mid-range OLED, and while there are not many new additions, it carries over what made the C4 great.

Picture quality is superb on the LG C5. Its vibrant, accurate color, strong contrast, and lifelike textures all combine to rival what you see on the best OLED TVs. Motion handling is good overall, but I did find some scenes where the C5 stumbled. (This was fixed with a quick trip to the picture settings.) One area where the C5 struggles is screen reflections in well-lit environments, which can impact darker images. It looks brilliant when viewed in dimmed conditions, however.

Sound quality has never been a strong point of LG C-series OLED TVs, and while the C5’s built-in 2.2-channel Dolby Atmos system sounds punchy and well-balanced, it won’t beat one of the best soundbars, which I’d recommend for the C5.

The C5 is easily going to be one of the best gaming TVs of 2025. It has a full suite of gaming features, including 4K 144Hz, VRR, ALLM and Dolby Vision gaming, smooth and responsive performance, and a ton of cloud gaming options for those without a console.

LG’s webOS 25 is the C5’s smart TV platform and alongside the previously mentioned new AI features, it continues to be one of the better interfaces on the market. Quick Cards in webOS 25 is a useful feature and LG’s Quick Menu continues to be excellent for those who like to regularly adjust picture settings.

The C5’s design is basic and safe, though a faux-marbled rear panel, solid aluminum stand, and trim profile help to give it a premium appearance. LG’s new AI Magic Remote is sleeker and more modern looking than previous Magic Remote versions but is only available in select regions.

LG C-series OLEDs are regularly among the best TVs when it comes to value for money. While pricey at launch, they will become more affordable over time as prices drop. It’s hard to ignore, however, that the still-available LG C4 is the better value option after numerous price drops as the C5 is only an incremental upgrade. Still, for anyone looking for a new TV, the C5 is a fantastic option.

LG C5 OLED TV review: Features

• Alpha a9 Gen 8 AI Processor
• New AI features including AI Sound Wizard
• Four HDMI 2.1 ports with up to 144Hz support

The LG C5 uses the same OLED Evo (EX) panel as its predecessor, the LG C4. It features LG’s upgraded Alpha a9 Gen 8 AI processor, which introduces new AI capabilities (more on those below) as well as a Brightness Booster that is not supported in the smaller 42- and 48-inch models. The C4 supports the Dolby Vision high dynamic range format, but not HDR10+. It also supports the Dolby Atmos and DTS:X sound formats.

For audio, the C5 features the same 2.2-channel, 40W Dolby Atmos built-in speaker system as the previous C4. Its range of sound modes includes Standard, Cinema and AI Sound Pro, as well as a new AI Sound Wizard (more on that below).

LG TVs are typically well-equipped for gaming and the C5 is no exception. While there are no upgrades from its predecessor, it still carries a full-suite of gaming features including 4K 144Hz, VRR (AMD FreeSync and Nvidia G-Sync), HGiG, Dolby Vision gaming and ALLM. It also features a Game Optimizer mode where settings can be adjusted, including a boost mode to reduce input lag.

The LG C5 uses the latest iteration of LG’s smart TV platform, webOS 25. This offers a plethora of AI capabilities including AI Search, an advanced search feature that looks for content based on the user’s criteria and questions; AI Concierge, where content is recommended based on a user’s viewing history; and an AI Art feature where users can create AI artworks (creating artworks cost credits that can be bought, but 100 credits are provided to start with).

Alongside AI Picture Wizard, a feature that lets users create a personalized picture mode based on visual prompts, LG has introduced AI Sound Wizard, a similar feature where users react to audio clips to establish a personal sound profile. For the home screen, Quick Cards (a feature introduced in webOS 24 that lets users organize apps based on categories such as Sports, Games, etc.) has been further streamlined.

LG C5 OLED TV review: Picture quality

• Vibrant color and strong contrast
• Superb detail
• Reflections in brighter environments

The LG C5’s peak HDR brightness (measured on a 10% white window) was 1,180 nits in Filmmaker Mode and 1,198 nits in Standard mode. Those results are an increase over the LG C4, which hit 1,065 nits and 925 nits in Filmmaker and Standard modes, respectively. Fullscreen HDR brightness (measured on a 100% white pattern) was between 195-200 nits, a slight drop from its C4 predecessor.

The LG C5’s upscaling of lower-resolution sources is impressive. An HD stream of Fight Club that I watched on Disney Plus got both a brightness and sharpness boost, giving the picture a 4K-like makeover. For standard-definition content (480p and below), the C5’s upscaling also managed to clean up textures, though they were still understandably on the fuzzy side.

Color on the LG C5 is superb. Watching a Dolby Vision stream of Elemental on Disney Plus, colors looked vibrant and dynamic, particularly in the scenes where Ember demonstrates her glass-making abilities and dances across the shimmering minerals. Another Dolby Vision stream, of Star Wars: The Last Jedi, showcased an abundance of reds in the throne room fight scene, which were displayed with real clarity and punch.

When I measured the C5’s HDR color gamut coverage, it hit 99.4% of the UHDA-P3 color space and 75.1% of BT.2020. These are both superb results and explain the C5’s excellent color.

Shadow detail and contrast were also brilliant on the C5. Watching the opening crime scene investigation sequence on a 4K Blu-ray of The Batman, detail in clothing was maintained in even the darkest of scenes without compromising deep blacks. In the same sequence, the bright lamps and torches contrasted well with the dark surroundings, with an accurate balance between bright and dark tones. Also, aerial shots of Gotham displayed punchy highlights in street lamps and neon signs while still maintaining the murky, dark tones in the surrounding buildings.

In the black and white scenes in Oppenheimer, shadows and highlights looked refined and authentic, with a wide range of gray tones in between. For these scenes, I turned Dynamic Tone Mapping on (it’s off by default in Filmmaker Mode), which gave white highlights a bolder, brighter look without sacrificing the balance of the gray and black tones.

I found that textures and details were refined and lifelike in pretty much all my viewing on the C5. Facial features and skin tones looked accurate, particularly in close-up shots in movies such as The Batman and Top Gun: Maverick. Textures in objects and clothing were also realistic and gave pictures a real sense of depth.

Motion is well handled on the C5. The intense flight sequences and long panning shots in Top Gun: Maverick looked smooth with only minimal blurring. I did find that the C5 struggled in some scenes, such as a panning shot of a rocky landscape in No Time To Die, but turning on Cinematic Movement in the TruMotion picture settings helped with this.

For viewing sports, I generally found Standard picture mode with TruMotion set to Natural to be the best option. With these settings active, back-and-forth action during a football game was accurately displayed. Those wanting a ‘smoother’ look can choose their own de-blur and de-judder settings, though I found it was best to keep these numbers low (around 3).

One area where the LG C5 does struggle is with reflections. With overhead lights on in our testing room, screen glare was very obvious compared to the best mini-LED TVs and more premium OLEDs such as the LG G4 and Samsung S95D, and resulted in a loss of black depth and shadow detail in darker scenes.

• Picture quality score: 4.5/5

LG C5 OLED TV review: Sound quality

• 2.2-channel Dolby Atmos speaker system
• Clear, detailed sound but limited bass
• New AI Sound Wizard is hit-and-miss

The LG C5’s built-in 2.2-channel, 40W speaker array supports the Dolby Atmos and DTS:X (via pass-through) sound formats, and its AI Sound Pro mode upmixes soundtracks to 11.1.2 channels – a step-up from the C4’s 9.1.2-channel upmixing.

My default choice for sound modes on TVs is usually the Movie/Cinema preset. With this active, placement of screeching tires and swerving traffic during the Batmobile chase in The Batman was accurate and well connected to the action on screen. There was a decent level of bass and good rumble to the Batmobile’s engine, but it still felt restrained compared to some of the best TVs for sound, such as the Sony Bravia 8. Dolby Atmos height effects were also limited and the soundstage could have been wider.

Interestingly, I found myself drawn to the TV’s AI Sound Pro mode. When activating this in the same scene of The Batman, everything was enhanced: the soundstage became wider and deeper, and bass, while still limited, was more tightly controlled. The overall sound was brighter, which some people may not like, but it felt more immersive. Still, the C5 could benefit from one of the best Dolby Atmos soundbars to complement its picture.

One of the new AI features in webOS 25 is AI Sound Wizard (the audio equivalent of the AI Picture Wizard). This lets you create a personal sound mode, which is done by listening to different audio clips to select your preferred sound profile. I tested three different profiles: Balanced, Natural and Rich, and Rich and Vivid but found they were all a little flat-sounding and still preferred the AI Sound Pro and Movie presets. Still, having that level of customization available is appreciated.

LG C5 OLED TV review: Design

• Sleek, premium design
• Solid, decent stand
• New AI Magic Remote, but only for some regions

The LG C5’s design is what you’d expect from a mid-range OLED TV. Its slim frame gives it a sleek look, with a trim profile and bezel-less screen that allows the picture to take center stage. The connections, including four HDMI 2.1 ports, are all easily accessible on the side of the screen – something you don’t always find in TVs from other brands.

The C5 doesn’t beat the premium design of flagship OLEDs such as the Samsung S95D or the Philips OLED909, but it has a solid aluminium pedestal stand and a new AI Magic Remote (only available in select regions, including the US) that’s sleeker, with a matte finish, a less cluttered layout and new AI Home Hub and Accessibility buttons. UK users will have to settle for a slightly updated version of the old Magic Remote which looks the same (even the numbered buttons are still present) but does come with the new buttons.

LG C5 OLED TV review: Smart TV & menus

• webOS 25 smart TV platform
• Quick Cards in home menu
• Extensive AI features

The C5 uses LG’s webOS smart TV platform. The latest iteration, webOS 25, mainly adds a ton of AI features, including AI Search, AI Concierge, AI Art and AI Sound Wizard. There are also upgrades and improvements to the AI Chatbot introduced in webOS 24.

When I posed questions to the Chatbot about improving picture brightness or sound, it provided advice on how to make those improvements. It struggled with more in-depth questions, but is still undeniably a good tool for some users.

LG has taken customization and personalization a step further with the new Voice ID, which is a very useful feature for families. The C5 supports multiple profiles to make sure content recommendations and settings are personal for each user, and if Voice ID is enabled, webOs will automatically recognise who is talking and adjust to that user accordingly.

Elsewhere, webOS 25 retains the Quick Cards feature, which provides useful hubs for categories such as Sports, Game and Accessibility. Choosing your favorite teams in Sports will link to any live or upcoming games, scores, and related content from YouTube and other streaming sites. The home screen’s layout looks very similar to webOS 24 and while the large banner image at top is annoying, the overall layout is user-friendly.

LG stands tall above the competition primarily through its Quick Menu, where settings can be quickly adjusted without moving away from the action on screen. There are plenty of picture and sound settings for those who like to experiment, and they are organized in a way that’s not too overwhelming for more casual users.

• Smart TV & menus score: 4.5/5

LG C5 OLED TV review: Gaming

• Full suite of gaming features
• Game Optimizer menu
• 9.2ms input lag time

The LG C5 is an excellent gaming TV. Its full suite of features include 4K 144Hz, VRR (both AMD FreeSync Premium and Nvidia G-Sync), HGiG, Dolby Vision gaming and ALLM support, all across four HDMI 2.1 ports. There is also a Game Optimizer mode where gaming settings can be adjusted, and the home menu’s Game Quick Card houses cloud-based gaming apps such as Amazon Luna and Nvidia GeForce Now as well as other gaming features and settings.

Gaming performance on the C5 is superb. Playing Battlefield V on Xbox Series X, intense battle sequences that required fast movement and targeting felt smooth, resulting in a seamless gaming experience with no screen tearing or blur. The C5’s picture quality added an extra layer to the game, displaying gorgeous visuals filled with vibrant color, stunning contrast and refined detail.

LG C5 OLED TV review: Value

• Feature-packed for the price
• Premium performance
• LG C4 still available for significantly cheaper

LG’s C-series OLED is always tough to judge on value. On the one hand, it’s a feature-packed TV with nearly everything you could need for movies and gaming and an excellent set of smart features to match. Although we have no 2025 model prices yet for the C5’s usual mid-range Samsung, Sony and Panasonic OLED competitors, the C5 is most likely to deliver the best bang for your buck of the lot.

On the other hand, while boasting a slight brightness boost and a new set of AI features, the C5 is very similar to its C4 predecessor. At the time of writing, the 65-inch C5 I tested will set you back $2,699.99 / £2,699.99 (at launch), whereas a 65-inch C4 now costs $1,499.99 / £1,499.99 – a very significant price difference. The price gap between the C4 and its C3 predecessor was easier to justify as the new model was such a step-up, but the same can’t be said for the C5.

However, the C5 is undeniably an excellent TV that justifies its price. Prices are also sure to drop over the coming months, but while the C4 is still available, that’s the model we’d recommend. Once it’s gone, though, the C5 is a worthy replacement.

How I tested the LG C5 OLED TV

• Tested over a week
• Tested using SDR and HDR sources
• Measurements taken using Portrait Displays’ Calman color calibration software

I first began testing the LG C5 OLED TV over a couple of days with casual viewing to determine its most accurate picture and sound modes.

After this, I moved on to critical viewing, using reference scenes from movies and TV shows. This included SDR sources (broadcast TV, HD streaming, DVD) and HDR (4K streaming and 4K Blu-ray). I used these to test the C5’s picture quality, looking at elements such as color, black levels, contrast, detail, motion and upscaling.

I used a Panasonic DP-UB820 4K Blu-ray player when playing discs including 4K Blu-ray. I also used an Xbox Series X to test the TV’s gaming features and performance.

Moving onto objective testing, I took measurements using a colorimeter, test pattern generator and Portrait Displays’ Calman color calibration software to record measurements.

I first took measurements of the C5’s brightness using both HDR and SDR white window patterns ranging in size from 1-100%. I also tested the C5’s grayscale and color accuracy, taking an average of the Delta-E values (the margin of error between the test pattern source and what’s shown on screen), looking for a result below 3.

I also tested the C5’s coverage of the UHDA-P3 and BT.2020 color spaces. Finally, I used a Leo Bodnar 4K HDMI Input lag Tester to test the C5’s input lag in milliseconds.
