LG 83-Inch Class OLED evo AI 4K G5 Series Smart TV Review

When LG announced their 2025 OLED lineup, the 83-inch G5 Series immediately stood out as the flagship offering that seemed to push every boundary of what’s possible in home entertainment. As someone who’s tested numerous high-end televisions over the years, I was particularly intrigued by LG’s claims about brightness improvements and AI enhancements. After spending several weeks with this $4,999 behemoth in my living room, here’s what I discovered.

Design Philosophy: Form Meets Function

The G5 Series continues LG’s tradition of ultra-thin, gallery-style designs that can hang flush against your wall. The elegance of this approach cannot be overstated—when mounted, the television becomes virtually indistinguishable from a piece of wall art. The included slim wall-mounting system is engineered to perfection, creating that sought-after “floating” appearance with virtually no visible gap between the display and your wall.

What I particularly appreciate is how LG has managed to make this massive 83-inch panel feel integrated rather than imposing. The minimalist aesthetic continues from the ultra-thin bezels to the barely-there stand options for those who prefer tabletop placement. The build quality is exceptional throughout, with premium materials used even in areas you might not immediately notice.

The “Brightest OLED Yet” – Reality Check

LG’s marketing highlights a claimed 45% brightness increase over previous models, and I can confirm this isn’t just marketing hype. Through the new Brightness Booster Ultimate technology, the G5’s OLED evo panel delivers genuinely impressive luminance levels that approach what you’d expect from traditional LED-backlit displays.

In testing HDR content—particularly challenging scenes with bright highlights—the G5 maintains exceptional dynamic range without the typical OLED trade-offs of dimming or black crush that plagued older models in well-lit environments. Watching “The Batman” (2022) during afternoon viewing with curtains partially open, I was amazed at how well shadow details remained visible while simultaneously appreciating the specular highlights on rain-slicked surfaces.

That said, while the G5 is dramatically brighter than previous OLEDs, it still doesn’t quite match the peak brightness of the very best mini-LED competitors like Samsung’s QN990C. However, what it offers instead is arguably superior: perfect black levels combined with enhanced brightness creates a contrast performance that LCD technology fundamentally cannot match.

AI Processor Performance: A Genuine Leap Forward

The Alpha 11 AI Processor Gen2 isn’t simply an incremental upgrade—it’s transformative. AI Picture Pro analyzes content in real-time, intelligently sharpening, denoising, and upscaling while maintaining natural textures. The processing is sophisticated enough that it rarely introduces the artificial “processed” look that plagues lesser upscaling solutions.

AI Super Upscaling deserves particular praise. Watching older content like “The Wire” or classic films from the Criterion Collection, the processor adds clarity without destroying the filmic quality. Grain structure is preserved while enhancing actual detail. For someone with a mixed media library spanning 480p DVDs to 4K HDR streaming, this versatility is invaluable.

The upscaling performance extends beyond visuals to audio processing as well. AI Sound Pro analyzes both content type and your room acoustics (when paired with compatible microphones) to optimize audio characteristics. The difference is noticeable—dialogue becomes clearer, music gains separation, and action sequences gain visceral impact.

Filmmaker Mode and Dolby Integration

As a cinephile, I deeply appreciate LG’s commitment to preserving creative intent through Filmmaker Mode. This preset disables harmful motion smoothing and preserves the director’s chosen frame rate and color profile. Combined with Dolby Vision IQ and Dolby Atmos support, the G5 delivers theatrical quality at home.

The Dolby Atmos implementation through built-in speakers is serviceable if you’re not immediately investing in a dedicated sound system. The upward-firing drivers create genuine overhead audio effects in supported content. However, given this television’s positioning and price point, pairing it with a dedicated Dolby Atmos soundbar or receiver is practically mandatory for realizing its full potential.

Gaming Capabilities: Serious Competition for Dedicated Monitors

Gaming performance on the G5 deserves extensive praise. The combination of 0.1ms response time, up to 165Hz refresh rate (when using compatible HDMI 2.1 ports), and comprehensive variable refresh rate support (NVIDIA G-Sync, AMD FreeSync Premium) creates a monitor-like gaming experience at massive scale.

Testing with both the PlayStation 5 and Xbox Series X, games like “Astro’s Playroom” and “Forza Horizon 5” showed no perceptible input lag. The Game Optimizer provides convenient access to all gaming-related settings, including aspect ratio controls—particularly useful for retro gaming enthusiasts.

The four HDMI 2.1 ports ensure you can connect multiple current-gen consoles alongside a 4K Blu-ray player without compromise. The ability to maintain full 4K/120Hz with VRR across all gaming sources is increasingly rare even among premium televisions.

webOS: Refined Yet Familiar

LG’s webOS smart platform has matured significantly. The latest iteration maintains the intuitive tile-based interface while adding meaningful improvements. App loading is swift thanks to increased processing power, and switching between sources is nearly instantaneous.

The inclusion of LG Channels offering free streaming content provides genuine added value, particularly for secondary viewing scenarios. The Re:New Program guarantee of updates for up to five years demonstrates LG’s confidence in the platform’s longevity—a meaningful consideration given the television’s significant investment.

Voice control via Alexa and Google Assistant integration functions reliably, as does interoperability with smart home ecosystems like Apple HomeKit and Matter-compatible devices. The AI Concierge feature, while occasionally helpful for content discovery, sometimes feels more novel than truly essential.

Perfect Viewing in Any Environment

The Glare Free certification from UL isn’t marketing gibberish—this OLED genuinely handles ambient light better than any OLED I’ve tested. The anti-reflective coating is sophisticated enough to minimize reflections while preserving image quality and black depth.

In my sunlit living room, watching HDR content during the day was genuinely pleasant, something I wouldn’t have considered with previous OLED generations. The viewing angle performance remains impeccable—colors and contrast remain consistent even at extreme off-axis positions, crucial for larger-format displays like this 83-inch behemoth.

Minor Considerations

While the G5 excels in most areas, a few considerations merit mention. The included remote, while stylish and functional, can feel small and crowded given the television’s premium positioning. A full-sized, more ergonomically designed option would be appreciated.

Sound quality, while adequate for casual viewing, becomes strained at higher volumes with action-heavy content. This is unsurprising given the exceptionally thin form factor, but reinforces that serious audiophiles will want to budget for external audio immediately.

The sheer size of the 83-inch model demands careful consideration of your space. While stunningly immersive when properly seated (I’d recommend a viewing distance of 8-10 feet minimum), it can overwhelm smaller rooms. During my testing period, I found the television forced a reconfiguration of my living room layout to accommodate optimal viewing distances.

Verdict

The LG OLED83G5WUA represents a genuine achievement in television technology. It delivers spectacular picture quality with significantly improved brightness, exceptionally refined processing, comprehensive gaming features, and smart functionality that won’t become obsolete within a year or two.

At $4,999, this television commands a premium price, but it earns that price through genuinely class-leading performance across virtually every metric. The combination of OLED perfection (perfect blacks, infinite contrast, exceptional viewing angles) with meaningfully improved brightness creates one of the most versatile and impressive displays available today.

For home theater enthusiasts who prioritize image quality above all else and have the appropriate space and budget, the LG G5 Series 83-inch OLED is difficult to fault. It represents the current pinnacle of LG’s considerable OLED expertise and will likely satisfy even demanding viewers for many years to come.
