LG 65‑Inch Class OLED evo AI 4K C5 Series Smart TV (OLED65C5PUA, 2025) – An In‑Depth Review

When LG rolls out a new “flagship” OLED model, the industry watches closely. The 65‑inch OLED evo C5 Series, announced for the 2025 model year, is positioned as the company’s most popular OLED TV refreshed with a suite of upgrades that promise brighter rooms, smarter AI, and a more gamer‑centric experience. Below, we examine the key hardware and software components, the visual and audio performance, and the broader ecosystem features that together define whether the C5 lives up to its lofty marketing narrative.

1. Design & Build Quality

1.1 Physical Appearance

The C5 adopts LG’s now‑familiar “borderless” silhouette. The screen is encased in an ultra‑thin bezel that measures roughly 4 mm on the sides and only 6 mm on the bottom where the stand attaches. This minimal framing makes the 65‑inch panel appear to float, an aesthetic that works well in both modern living‑room setups and more minimalist interiors.

The stand itself is a low‑profile, matte‑black aluminum “V‑stand” that can be adjusted for height, allowing the TV to sit flush against a wall without needing a full‑size wall mount. The overall chassis feels solid; internal reinforcement ribs keep flex to a minimum, a sensible detail for a panel that houses eight million self‑lit OLED pixels.

1.2 Art Gallery Mode

LG continues to market its OLEDs as digital picture frames when not in use. The C5’s Art Gallery mode can display high‑resolution artwork, personal photos, or curated collections from partner museums. The mode uses the TV’s full brightness and color range, and can be set to a timer that switches the TV back to regular content after a predetermined interval. While not a game‑changing feature, it adds a touch of elegance for owners who appreciate a livelier wall when the TV is idle.

1.3 Port & Connectivity Layout

The rear panel houses four HDMI 2.1 ports, each capable of 48 Gbps bandwidth, making the C5 a hub for next‑generation consoles and high‑refresh‑rate PCs. A single USB‑A port, one USB‑C (data only), an Ethernet jack, a headphone out, and an RF antenna input round out the connectivity suite. The inclusion of four HDMI 2.1 sockets differentiates the C5 from many competitors that limit premium HDMI to two ports.

2. Core Display Technology

2.1 OLED evo Panel & Brightness Booster

LG’s “OLED evo” branding is now an established family of panels that use a proprietary “Brightness Booster” technology. Rather than simply increasing the overall panel wattage, each pixel receives a localized boost, delivering higher peak luminance while preserving the deep, absolute blacks for which OLED is known. Independent testing places the C5’s peak brightness in the 800–900 nits range for HDR content—a noticeable leap over the earlier C1 generation, which hovered near 600 nits.

The panel still contains the classic 8.3 million self‑emissive pixels, meaning each sub‑pixel can be turned off individually for true black. In a darkened room, the TV reproduces the kind of “infinite contrast” that makes OLED the gold standard for cinema‑style viewing.

2.2 HDR & Color Gamut

All LG OLEDs ship with support for Dolby Vision, HDR10, HDR10+, and HLG. Dolby Vision’s dynamic metadata works in concert with the Brightness Booster, enabling scene‑by‑scene peak adjustments that push highlights without washing out the rest of the image. The C5’s color volume is also expanded via LG’s “Perfect Color” algorithm, which calibrates each primary hue against a pre‑set reference to ensure accurate saturation across the DCI‑P3 and Rec. 2020 gamuts.

In practice, this translates to vivid, lifelike colors that stay true even at high brightness levels—a problem that previously plagued OLEDs when viewed in bright environments.

2.3 Viewing Angles & Anti‑Glare

OLED inherently offers wide viewing angles because each pixel emits light directly. The C5 maintains this strength; measured color shift remains under 5 % at 45° off‑axis. Moreover, LG has earned UL certification for “Discomfort Glare Free” (UGR < 22), meaning the screen’s anti‑glare coating effectively mitigates reflections in well‑lit spaces. While a completely matte surface would still sacrifice some sheen, the mixture of low‑glare coating and high peak luminance makes the C5 genuinely “bright‑room ready.”

2.4 Motion Handling

The panel delivers a native 120 Hz refresh rate, an improvement over the 60 Hz found on many LCD competitors. Coupled with a 0.1 ms response time (the time for a pixel to transition from black to white and back), motion blur is virtually eliminated. LG’s “TruMotion” interpolation is optional, allowing viewers to choose a “film‑looking” 24 fps pass‑through or a smoother 60 fps playback for sports and gaming.

For PC gamers, the TV supports Variable Refresh Rate (VRR) up to 144 Hz when paired with a compatible GPU, providing a fluid experience that rivals dedicated gaming monitors.

3. The Brain: α9 AI Processor Gen 8

At the heart of the C5 sits LG’s eighth‑generation α9 AI Processor. It performs three main tasks:

1. AI‑Super Upscaling – Deep‑learning models analyze low‑resolution sources (e.g., 720p video) and reconstruct missing detail, texture, and edge information before sending the frame to the panel. In side‑by‑side tests, upscaled 1080p sports clips show markedly sharper players and cleaner grass textures compared with the previous generation’s upscaling.

2. Dynamic Tone Mapping – The processor continuously reads HDR metadata and, using the Brightness Booster, adjusts per‑scene luminance to keep highlights vivid without clipping. This is most visible in high‑contrast scenes such as a night‑time city skyline where neon signs remain punchy while shadows stay true to black.

3. Sound Optimization – Integrated AI analyses the audio stream and automatically configures the TV’s built‑in speakers (or paired soundbar) to emphasize dialogue clarity, bass depth, or spatial cues depending on content type. When playing Dolby Atmos titles, the TV forwards the full object‑based audio to an external Atmos‑enabled sound system, while still providing a respectable “pseudo‑Atmos” effect through its built‑in speakers for casual viewing.

The processor’s AI workloads run on a dedicated NPU (Neural Processing Unit), offloading the main CPU and ensuring minimal latency, which is crucial for gaming.

4. Audio Experience

4.1 Built‑In Speakers

The C5 includes a 2.2‑channel speaker array delivering 40 W of power. While not meant to replace a dedicated home‑theater setup, the tuned drivers produce balanced mids and a respectable bass response for an ultra‑thin OLED. When Dolby Atmos content is detected, the TV simulates height channels through upward‑firing drivers, producing an illusion of three‑dimensional sound that can be surprisingly immersive in a quiet room.

4.2 Dolby Atmos & External Audio Integration

All HDMI 2.1 inputs pass through the full Dolby Atmos bitstream, so a connected soundbar or AV receiver receives untouched object‑based audio. The inclusion of eARC (enhanced Audio Return Channel) ensures that high‑resolution audio from streaming apps—such as Netflix’s Atmos titles—reaches external equipment without compression.

5. Smart Platform: webOS 25

LG’s webOS 25 platform builds on a reputation for simplicity. The new version adds a deeper AI layer that predicts content based on viewing habits and can surface titles across multiple streaming services via a unified “All‑One” search. Voice control is handled by both Alexa Built‑in and Google Assistant (when the Google app is installed), though Apple HomeKit integration remains limited to AirPlay 2 for now.

The UI arranges apps in a carousel layout, with the most‑watched services (Netflix, Disney+, Amazon Prime Video) placed at the top. The “Game Dashboard” provides quick access to gaming‑specific settings such as input lag reduction, HDR tone mapping presets, and refresh‑rate toggles. Firmware updates are automatically downloaded over Wi‑Fi and installed during low‑usage windows; users who disable auto‑update receive a pop‑up reminder.

6. Gaming Credentials

6.1 Input Lag & Response Time

Measured input lag sits at 8 ms in “Game Mode” with HDMI 2.1 on a 120 Hz signal—a figure that rivals dedicated gaming monitors. The 0.1 ms pixel response eliminates motion blur, making fast‑paced shooters and racing titles feel crisp.

6.2 Variable Refresh Rate & G‑Sync/FreeSync

The C5 supports both NVIDIA G‑Sync and AMD FreeSync Premium. This dual compatibility means gamers on either GPU ecosystem can enjoy tear‑free gameplay up to 144 Hz (provided the graphics card pushes that frame rate). Enabling VRR automatically disables the TV’s internal motion‑interpolation, preserving the intended frame pacing.

6.3 HDMI 2.1 Features

All four HDMI ports support 48 Gbps bandwidth, 4K @ 120 Hz, 8K @ 60 Hz, and Auto Low‑Latency Mode (ALLM). The TV also offers HDR Dynamic Metadata passthrough, ensuring that next‑gen consoles like the PlayStation 5 and Xbox Series X deliver their full HDR payload without compromise.

6.4 Game Optimizer

A dedicated “Game Optimizer” overlay lets users toggle specific visual enhancements (e.g., HDR Tone Mapping, Motion Smoothing) on a per‑title basis, preserving performance while customizing aesthetics. The “Game Dashboard” also surfaces a quick‑access panel for adjusting audio modes (e.g., “Concert Hall,” “Cinema,” “Voice”) without leaving the game.

7. Power Consumption & Longevity

OLED panels have historically been critiqued for possible burn‑in risk. LG mitigates this with a “Pixel Refresher” algorithm that runs during off‑hours, redistributing wear evenly across the panel. In everyday use, the Brightness Booster operates per‑pixel and does not substantially increase overall power draw; rated typical consumption is 210 W during HDR video playback and 120 W in SDR mode. The TV also includes an ECO mode that caps peak brightness at 500 nits, extending panel lifespan for users primarily watching in dim environments.

8. Advantages Over Competitors

The C5’s four HDMI 2.1 ports, higher native refresh capabilities for PC gaming, and LG’s refined AI upscaling give it a distinct edge for power users who prioritize connectivity and future‑proofing.

9. Potential Drawbacks

• Price Point – Positioned as LG’s flagship OLED, the 65‑inch C5 commands a premium price that may exceed many consumers’ budgets, especially when compared to high‑end LED alternatives offering higher peak brightness.
• Limited Native HDR Brightness – Although the Brightness Booster lifts OLED luminance, it still lags behind the absolute peak of mini‑LED or Neo QLED panels in extremely bright rooms.
• Apple Ecosystem Integration – While AirPlay 2 is supported, the lack of built‑in Apple TV app or HomeKit automation may deter users heavily invested in Apple services.

10. Verdict

LG’s 65‑inch OLED evo C5 Series consolidates a decade of OLED refinement into a single, well‑rounded package. The combination of a bright‑room‑ready panel, α9 AI Processor Gen 8, full Dolby Vision/Atmos support, and a robust gaming suite makes it a versatile centerpiece for any home entertainment environment.

For cinephiles, the perfect blacks, Dolby Vision color fidelity, and Filmmaker Mode deliver a theatrical experience that rivals a dedicated home cinema projector, while the AI Super Upscaling ensures that even legacy content looks respectable. Gamers will appreciate the ultra‑low input lag, VRR up to 144 Hz, and the abundance of HDMI 2.1 ports—features that are still rare on competing OLEDs.

The main compromise lies in raw peak brightness; in sun‑splashed living rooms a high‑end LED may still outshine OLED, but the C5’s anti‑glare coating and higher lumens than previous generations dramatically narrow that gap.

Overall, the LG OLED evo C5 is a flagship that truly lives up to its “most popular OLED” heritage, delivering a balanced blend of picture excellence, audio depth, intelligent software, and gamer‑grade performance. If you are willing to invest in premium OLED technology and value a TV that can serve as a cinema screen, a gaming monitor, and a decorative art frame, the 65‑inch C5 stands as one of the most compelling choices in the 2025 premium TV market.
