📌 The Bottom Line

The LG C5 OLED 65-inch remains one of the most complete premium televisions you can buy in 2026—provided you find it at the right price. It combines OLED’s perfect black levels with strong HDR brightness, excellent image processing, Dolby Vision, four full-bandwidth HDMI 2.1 ports and gaming support up to 4K at 144Hz.

The C5 is a 2025 model, not LG’s current 2026 release. That matters because the newer LG C6 is now available. However, the C5 can still be the better-value purchase when retailers discount it substantially below the C6.

Its biggest strengths are cinematic contrast, accurate color, wide viewing angles and outstanding gaming responsiveness. Its main weaknesses are average built-in sound, visible reflections from direct light sources and the usual OLED precautions surrounding prolonged static content.

Smart Gear Select verdict: The LG C5 is an excellent all-purpose OLED for movies, streaming, sports and gaming. Buy it when its discounted price creates a meaningful saving over the newer C6.

LG C5 OLED 65-Inch Review Summary

Smart Gear Select Score

Design and Build Quality

The LG C5 continues the clean, understated design that has made the C-series popular with home-theater buyers. Its screen is surrounded by extremely slim borders, while the upper section of the television remains impressively thin when viewed from the side.

The lower rear section is thicker because it contains the processor, connections, power supply and speakers. This is normal for an OLED television and does not detract from the appearance when the TV is viewed from the front.

The included stand provides stable desktop placement without making the television look unnecessarily bulky. Buyers planning to use a soundbar should check its height before installation to ensure it does not cover the bottom edge of the screen or interfere with the remote sensor.

The 65-inch model can also be wall-mounted using a compatible VESA bracket. Because a 65-inch OLED panel is large and relatively delicate, installation is safer with two people or a professional mounting service.

OLED Picture Quality

The main reason to buy the LG C5 is still its OLED panel. Every pixel produces its own light and can switch off independently, allowing the television to display true black beside a bright object without the halos or blooming commonly seen on locally dimmed LED televisions.

This pixel-level control gives movies and television series exceptional depth. Dark scenes retain convincing black levels, while stars, lamps, subtitles and other bright elements remain sharply defined against the surrounding darkness.

Viewing angles are another major advantage. Color and contrast remain consistent when the screen is watched from the side, making the C5 a strong choice for wide seating arrangements and family living rooms.

The C5 does not use the advanced four-stack OLED panel found in LG’s higher-end G5, and it does not contain Micro Lens Array technology. Instead, it uses an OLED evo panel with LG’s standard Brightness Booster system.

How Bright Is the LG C5?

The LG C5 is brighter than many earlier C-series OLED televisions, especially when displaying small and medium-sized highlights. However, buyers should not expect the sustained brightness of a flagship Mini-LED television or the brighter LG G5.

Independent real-scene measurements generally place the C5 in the approximately 1,000-nit class, depending on the selected picture mode, firmware, tone-mapping settings and content. This is enough to give sunlight, explosions, reflections and other HDR highlights strong visual impact.

It is also a more capable daytime television than older OLED models. SDR content remains visible in a moderately bright room, although direct reflections from windows or exposed lamps can still be distracting because the panel has a glossy finish.

For the best result, avoid placing the television directly opposite a large uncovered window. Curtains, blinds or thoughtful room positioning will improve perceived contrast more effectively than simply increasing picture brightness.

HDR and Dolby Vision Performance

The LG C5 supports Dolby Vision, HDR10 and HLG. Dolby Vision support remains an important advantage over Samsung OLED televisions, which continue to prioritize HDR10+ instead.

OLED’s perfect black level helps HDR highlights appear more intense, even when the measured peak brightness is lower than that of a powerful Mini-LED television. A bright object surrounded by true black often looks more dramatic than a higher measured brightness figure suggests.

Filmmaker Mode is the best starting point for viewers who want a natural image with limited artificial sharpening and motion processing. Cinema modes are also suitable for movies and premium streaming content.

Dynamic Tone Mapping can brighten difficult HDR scenes, but it may alter the original brightness presentation. Viewers who prioritize creator intent should compare it with tone mapping disabled before deciding which version they prefer.

Color Accuracy and Image Processing

The C5 is powered by LG’s α9 AI Processor 4K Gen8. It handles upscaling, noise reduction, object recognition, tone mapping, motion processing and sound optimization.

High-quality 4K content looks exceptionally detailed, while lower-resolution television broadcasts and compressed streams receive effective cleanup. The processor cannot restore detail that does not exist in a poor source, but it can reduce compression artifacts and make lower-quality material easier to watch.

Color accuracy is strong when an appropriate picture mode is selected. Most buyers will not need professional calibration. Filmmaker Mode or Cinema mode should provide a more accurate starting point than Vivid or Standard mode.

LG’s Smooth Gradation feature can reduce visible color banding in heavily compressed streaming content. Using it at a low setting is generally safer because stronger settings may remove fine image detail.

Motion Handling for Movies and Sports

OLED pixels change state almost instantly, giving the C5 excellent motion clarity during sports, action movies and gaming. Fast-moving objects remain clean without the long trails sometimes visible on slower LCD panels.

The same fast response can make slow camera pans in 24-frame-per-second movies appear slightly choppy. This is known as OLED stutter and is different from motion blur.

LG’s Cinematic Movement setting can reduce the effect without creating the overly smooth “soap opera” appearance associated with aggressive motion interpolation. Viewers who dislike interpolation can leave TruMotion disabled and preserve the original film cadence.

Gaming Performance

The LG C5 is one of the strongest gaming televisions in its class. All four HDMI inputs support HDMI 2.1 bandwidth, allowing owners to connect multiple modern consoles, a gaming PC and an eARC sound system without constantly changing cables.

The panel has a 120Hz native refresh rate and supports variable refresh rates up to 144Hz with a compatible gaming PC. PlayStation 5 and Xbox Series consoles operate at up to 4K and 120Hz because that is the maximum output supported by those consoles.

Gaming features include:

• 4K gaming at up to 144Hz from a compatible PC
• 4K gaming at up to 120Hz from supported consoles
• Variable Refresh Rate
• Auto Low Latency Mode
• NVIDIA G-Sync compatibility
• AMD FreeSync Premium
• HGiG support for HDR gaming
• LG Game Optimizer dashboard

LG advertises a response time as low as 0.1 milliseconds. This refers to the OLED pixel response time, not total controller-to-screen input lag. Actual input lag is higher but remains low enough for responsive competitive and single-player gaming.

Game Optimizer provides quick access to refresh-rate information, VRR status, black-level adjustment and game-specific picture presets. HDR brightness can be slightly lower in Game Optimizer than in some movie modes, but the overall gaming presentation remains impressive.

Four HDMI 2.1 Ports

Many competing televisions offer only two high-bandwidth HDMI inputs. The C5 provides four HDMI 2.1 ports, giving it an important advantage for buyers with several gaming or home-theater devices.

One HDMI input supports eARC for connecting a soundbar or AV receiver. After assigning one port to eARC, three high-bandwidth inputs remain available for consoles, PCs and media players.

The television also includes USB connections, Ethernet, optical digital audio output and wireless connectivity. Exact port placement and regional broadcast tuners may vary between model suffixes.

webOS 25 and Smart TV Features

The LG C5 launched with webOS 25. The interface supports major streaming applications, user profiles, voice search, screen casting and smart-home integration.

The updated Magic Remote combines conventional buttons with LG’s pointer-based navigation system. Some users enjoy moving an on-screen cursor by pointing the remote, while others may prefer navigating with the directional controls.

WebOS remains responsive and feature-rich, although its home screen includes recommendations and promotional content. During setup, review the privacy and advertising options and disable any data-sharing features you do not need.

The C5 is included in LG’s webOS Re:New program. LG states that supported 2025 televisions can receive four major webOS upgrades across five years, although the timing and availability of individual features can vary by region.

Built-In Sound Quality

The built-in 2.2-channel audio system is adequate for news, casual streaming and everyday television. Dialogue is generally clear, and AI Sound modes can expand the perceived soundstage.

However, the thin cabinet cannot produce the bass depth, separation or scale expected from a premium home-theater system. Buyers investing in a 65-inch OLED should consider adding a soundbar, subwoofer or AV receiver.

OLED Burn-In: Should You Be Concerned?

Permanent image retention remains possible on any OLED television when the same static elements are displayed repeatedly for extremely long periods. Examples include continuous news tickers, fixed game interfaces, channel logos or using the television as a desktop monitor with an unchanged taskbar.

LG includes protective systems such as pixel shifting, logo brightness adjustment, screen savers and scheduled pixel-cleaning routines. These features significantly reduce the risk during normal mixed use.

Most households that alternate between films, television, games and streaming apps should not experience a problem. Buyers planning to display a static dashboard or the same news channel for many hours every day may be better served by a high-quality Mini-LED television.

LG C5 vs LG C4

The C5 is an evolutionary upgrade rather than a complete redesign of the C4. It uses a newer α9 Gen8 processor and can deliver somewhat higher brightness, but the two televisions remain similar in general picture quality, gaming support and overall design.

The C4 can be the better-value choice when it costs substantially less. Paying a large premium for the C5 over a discounted C4 is difficult to justify unless the improved brightness and newer software-support window are important to you.

LG C5 vs LG C6

The LG C6 is the newer 2026 successor. That makes price the deciding factor for most buyers.

The C5 remains attractive when clearance discounts place it meaningfully below the C6. When the two models are close in price, the newer C6 is generally the more future-facing purchase because it starts with a newer model year and a longer remaining support cycle.

Compare the final checkout prices rather than the original recommended retail prices. Television discounts change frequently, and a newer model may occasionally cost less than remaining stock of the older one.

⚖️ Pros and Cons

Who Should Buy the LG C5?

The LG C5 is a strong choice for:

• Movie fans who value perfect black levels and Dolby Vision
• PlayStation 5 and Xbox Series owners
• PC gamers targeting 4K at refresh rates above 120Hz
• Homes with wide seating arrangements
• Buyers who need several HDMI 2.1 inputs
• Anyone finding the C5 at a meaningful clearance discount

Who Should Skip It?

Consider another television if:

• Your room receives strong direct sunlight throughout the day
• You display the same static content for many hours every day
• You need extremely powerful built-in speakers
• The newer LG C6 costs only slightly more
• A discounted LG C4 offers nearly the same experience for much less

🎯 Final Verdict

The LG C5 OLED 65-inch is an excellent television built around the qualities that continue to make OLED desirable: perfect black levels, precise pixel-level contrast, wide viewing angles and exceptionally fast response.

Its α9 Gen8 processor produces clean upscaling, the Brightness Booster panel delivers convincing HDR highlights, and its four HDMI 2.1 inputs make it unusually flexible for serious gaming setups.

The C5 does not reach the extreme brightness of LG’s flagship G-series, and the improvement over the C4 is not revolutionary. It is also no longer LG’s newest C-series television in 2026.

Nevertheless, the C5 remains an easy recommendation when discounted. It offers premium home-theater picture quality, class-leading gaming connectivity and a mature smart-TV platform without forcing buyers into flagship pricing.

Smart Gear Select Score: 9.1/10
