Display & Picture Performance

OLED evo & Brightness Enhancements

Where earlier OLEDs often struggled in very bright rooms, LG’s G5 introduces a new panel architecture (sometimes referred to as Primary RGB Tandem OLED / “four-stack” architecture in reviews) designed for higher luminance. This architecture layers red, green, and blue emitters in a way that allows stronger brightness while retaining pure OLED black levels.

In real-world testing (for larger LG G5 models), HDR peak brightness has been measured around 2,200+ nits in small window patterns, which is very competitive, approaching or surpassing many premium Mini LED TVs in highlight performance.

Additionally, LG adds anti-glare / anti-reflective coatings to reduce reflections, making the G5 more usable in brighter viewing settings than past OLEDs.

Overall, this means: deep blacks, excellent contrast, and highlights that punch — making HDR content like explosions, sunrises, and specular reflections truly shine.

Color, Accuracy & HDR Rendering

LG’s OLEDs have always been strong in color fidelity, and the G5 continues that:

• Wide color gamut coverage, strong DCI-P3 and Rec. 2020 mapping
• Dolby Vision, HDR10, HLG support give broad HDR content compatibility
• Tone mapping is handled well — bright scenes don’t clip badly, dark scenes retain nuance
• Upscaling from lower-resolution sources is excellent, thanks to the Alpha 11 AI engine which analyzes scenes and applies noise reduction, edge enhancement, and adaptive contrast

Particularly in Filmmaker Mode, content is presented as intended, with minimal processing, preserving detail, skin tones, and creative intent. For HDR, the combination of brightness and tone mapping helps maintain realism.

Motion & Gaming

The G5 brings real advantages for gamers:

• It supports 4K at up to 165 Hz (i.e. more than many other TVs) — meaning highly fluid motion in gaming.
• Variable Refresh Rate (VRR) and FreeSync Premium, plus NVIDIA G-Sync compatibility help eliminate tearing.
• Input lag in gaming modes is impressively low (in testing ~9ms range in “Boost” mode) — suitable even for competitive gaming.
• The Game Optimizer / Game Dashboard on LG TVs allows real-time switching of settings like black level, input, aspect ratio, HDR mode, etc.
• LG’s gaming ecosystem (Gaming Portal, cloud gaming options, etc.) further enhance usability for gamers.

Because of this, the G5 isn’t just a “movie OLED” — it’s a strong hybrid for gaming + cinema.

Audio & Sound

LG equips the G5 with a 4.2-channel speaker system (built into the TV), which is a step up from more minimal OLED sound arrays. While it doesn’t replace a dedicated home theater, the built-in sound is capable, especially for casual viewing.

Key audio features:

• Dolby Atmos support, allowing spatial audio when the source provides it
• AI Sound Pro / Sound modes that adapt to content type (dialogue, movie, music)
• WOW Orchestra which allows the TV’s internal speakers and a compatible LG soundbar to work together in sync, expanding the soundstage

In practice, the audio is clear, dialogue legible, and midrange solid — but high-end users will still want a soundbar or AV receiver for fully immersive cinema audio.

Smart Platform, Interface & Features

webOS 25 & AI Enhancements

LG’s webOS is mature and feature-rich. The 2025 G5 gets upgrades like:

• Richer AI-based adaptability (user profiles, voice recognition, automatic switching)
• Faster navigation, smarter recommendations, and dynamic home screen layout
• AI Concierge / Chatbot-style interaction in some markets
• Support for multiple voice assistants (Google Assistant, Alexa, LG ThinQ)

Voice & Remote

• The AI Magic Remote (or variant) allows point, voice, and scroll interaction
• Voice recognition may switch profiles, suggest content, or optimize settings
• Remote design in some markets is streamlined and minimalist

Connectivity & Ecosystem

• HDMI 2.1 x4 means you can connect multiple consoles/PCs without bandwidth compromises
• eARC support for high-quality audio passthrough to soundbars or receivers
• AirPlay, Chromecast-like casting, screen mirroring, and cross-ecosystem compatibility
• Integration with LG ThinQ / smart home / Matter where available

In short, the G5 is as smart as it is visually capable.

Design & Build

• The G5 is designed for wall-mount first: ultra-thin, flush mount, minimal bezel — it looks like a framed display on your wall.
• In many regions, a pedestal stand is optional (some models come without stand).
• The panel is sturdy and well-built; rear connectivity is clean, with cable routing support to keep aesthetics tidy.
• When mounted correctly, the G5 gives a gallery look — gorgeous in appearance when off or on.

Because LG expects many buyers to mount it, the design emphasizes that presentation.

Who Should Buy the LG OLED55G5?

The 55″ G5 is ideal for:

• Buyers who want top-tier image quality in a manageable format

The LG OLED55G5WUA (2025 G5 series) is a statement: OLED technology still has room to grow. Its combination of deeper brightness, refined panel architecture, rich color, and full-featured smart + gaming support positions it as one of the most compelling 55″ TVs you can buy in 2025. It’s not without trade-offs, but for cinephiles, gamers, and anyone demanding premium picture and design in a manageable size — the G5 is hard to beat.
