LG OLED65C5

The LG OLED65C5 upholds the C series’ reputation as the benchmark for mid-range OLED TVs. This 2025 edition brings targeted improvements while retaining the strengths that made its predecessors so successful: outstanding picture quality, top-tier gaming performance, and an attractive price point for an OLED television. With its α9 AI Gen8 processor and the new webOS 25 interface, this 65-inch model stands out as a balanced choice for both movie enthusiasts and demanding gamers.

Design and Technical Construction

The LG C5 adopts a minimalist approach with a 4.51 cm thick profile (without stand), true to the brand’s clean aesthetic. Its 47 cm wide central metal stand ensures optimal stability while leaving space for a soundbar, though the design offers little room for bulkier models. VESA 300 x 200 mm compatibility makes wall mounting easy—a solution often preferred to fully showcase the elegance of this 18.5 kg TV (with stand).

The finish combines subtlety and robustness, with quality materials that justify its durability certification. The repairability index of 7.3/10 reflects an environmentally conscious design, while the controlled average power consumption of 76.6W confirms the energy efficiency of OLED technology.

Fourth-Generation OLED evo Display Technology

At its core, the C5 features a fourth-generation 4K OLED evo panel, a technology that gives each pixel individual control for absolute blacks and infinite contrast. This “Perfect Black” certification by UL ensures remarkable image fidelity, especially appreciated in dark scenes where details emerge with surgical precision.

The most notable improvement concerns peak brightness, now reaching 1,150 cd/m² compared to 959 cd/m² on the C4. This roughly 20% increase allows for better HDR content readability while maintaining the rich color reproduction characteristic of OLEDs. The Brightness Booster technology automatically optimizes brightness based on displayed content, while OLED Color reproduction is certified 100% accurate by Intertek.

Unlike the high-end G5 series, the C5 retains traditional WOLED technology rather than the new Tandem OLED approach. This technical choice helps keep costs down while maintaining excellent image performance for most uses.

Next-Generation Gaming Performance

The C5 truly excels in gaming, with full support for variable refresh rates up to 144Hz across all four HDMI 2.1 ports. This setup ensures optimal compatibility with the latest generation consoles and high-end PC graphics cards, delivering outstanding smoothness in the most demanding titles.

With a response time under 0.1 ms and measured input lag below 6 ms at 120Hz, this TV ranks among the top gaming references. NVIDIA G-Sync and AMD FreeSync Premium technologies eliminate screen tearing, while ALLM (Auto Low Latency Mode) automatically switches to optimized settings as soon as a gaming signal is detected.

Dolby Vision Gaming is a welcome innovation, enabling optimized HDR even at 4K 120Hz. The integrated Gaming Dashboard provides quick access to essential settings without leaving the game—a particularly handy feature for adjusting parameters based on content type.

Artificial Intelligence and α9 Gen8 Image Processing

The α9 AI 4K Gen8 processor is the brain of this TV, orchestrating a suite of AI-based image enhancement technologies. AI Super Upscaling 4K analyzes low-resolution content in real time to upscale it to near-native 4K quality, especially effective for TV broadcasts and older streaming content.

Dynamic Tone Mapping Pro adapts brightness scene by scene, optimizing HDR rendering according to each scene’s characteristics. This technology works in tandem with AI Brightness Control, which automatically adjusts overall brightness based on ambient lighting detected by the built-in sensor.

AI Genre Selection is an interesting innovation: the processor identifies the type of content (movie, sports, animation) and automatically applies the corresponding picture settings. This approach simplifies daily use while ensuring optimal rendering for every type of program.

webOS 25 System and Modern Connectivity

The new webOS 25 interface offers enhanced personalization with individual user profiles—a valuable feature for multi-user households. The system’s responsiveness is exemplary, with smooth navigation and quick access to popular streaming apps.

Connectivity meets modern demands: four HDMI 2.1 ports with eARC support on port 2, three USB 2.0 ports, Ethernet connection, and digital optical output. Wi-Fi 6 and Bluetooth 5.3 provide up-to-date wireless connectivity, while Apple AirPlay 2 and Google Cast compatibility make it easy to share content from mobile devices.

The new Magic Remote features a pointer and scroll wheel for intuitive navigation, complemented by voice control for hands-free operation. The LG ThinQ app extends control options from a smartphone, turning it into an advanced remote.

Audio Quality and Dolby Atmos Technology

The 2.2 channel 40W audio system benefits from AI Sound Pro processing, which virtualizes an 11.1.2 sound environment. This technology analyzes audio content in real time to create convincing spatialization, especially effective with Dolby Atmos content.

The Clear Voice Pro feature uses artificial intelligence to enhance dialogue clarity—a valuable function for movies with complex soundtracks. WOW Orchestra allows the TV to synchronize with a compatible LG soundbar, creating an extended audio system with no latency.

However, LG has removed DTS audio passthrough support from its entire 2025 lineup—a decision that may disappoint home theater amplifier owners using this format. This limitation mainly affects Blu-ray discs and some specialized streaming content.
