Samsung Neo QLED vs LG OLED: The Ultimate 65" Premium TV Battle of 2025

When I first started reviewing TVs a decade ago, the choice between brands was mostly about subtle picture differences and smart TV interfaces. Today's premium TV market is dramatically different – we're witnessing a genuine technology revolution that's fundamentally changing how we think about home entertainment. The Samsung 65" QN90F Neo QLED and LG OLED evo G5, both released in 2025, represent the pinnacle of two competing display philosophies that have been battling for supremacy.

Understanding the Display Technology War

Before diving into specifics, it's crucial to understand what makes these TVs fundamentally different. The Samsung QN90F uses Mini-LED technology – imagine thousands of tiny LED backlights arranged behind the screen, each capable of dimming independently. This creates what's called "local dimming zones" where different parts of the screen can be brighter or darker simultaneously. Samsung combines this with quantum dots – microscopic particles that convert blue light into precise red and green wavelengths, creating more accurate and vibrant colors.

The LG G5 OLED, on the other hand, uses OLED technology where each individual pixel produces its own light and can turn completely off when displaying black. Think of it like having 8.3 million tiny light bulbs that can each be controlled independently. LG's 2025 innovation is their new 4-Stack RGB Tandem structure – essentially stacking four layers of light-emitting material together, allowing each pixel to produce significantly more light without burning out faster.

Having tested both technologies extensively, I can tell you that each approach solves different problems and excels in different scenarios. The key is understanding which strengths matter most for your specific situation.

Picture Quality: Where Science Meets Art

Brightness Performance and HDR Impact

The most significant development in 2025 has been the brightness arms race, and it's reshaping how we think about TV placement in our homes. The Samsung QN90F delivers exceptional peak brightness reaching up to 1,900 nits in small highlights – that's bright enough to create genuinely eye-searing reflections of sunlight or explosions in movies. In my testing, this translates to HDR content that maintains its impact even when you're watching during a sunny afternoon with windows open.

Samsung's Brightness Optimizer technology continuously analyzes the ambient light in your room and adjusts the picture accordingly. I've found this particularly effective during those transition periods at dusk when room lighting changes gradually – the TV adapts seamlessly without you noticing.

The breakthrough story of 2025, however, is the LG G5's dramatic brightness improvement. Previous OLED TVs topped out around 700-800 nits, making them unsuitable for bright rooms. LG's new Brightness Booster Ultimate technology, combined with their 4-Stack Tandem panel, delivers up to 45% higher brightness than previous generations. In practical terms, this means OLED is finally viable in moderately lit rooms – something that wasn't possible just two years ago.

Contrast and Black Level Performance

Here's where the fundamental technology differences become most apparent. The LG G5 achieves what we call "infinite contrast" because its pixels can turn completely off, creating true black. When you're watching a movie with a night scene, those dark areas aren't just very dark – they're the same black as when the TV is completely off. This creates an almost three-dimensional quality to images that's particularly striking in dark room viewing.

During my testing of the Samsung QN90F, the local dimming performs impressively well, creating very deep blacks through its Quantum Matrix Technology Pro. However, physics still applies – there's backlighting behind the panel, so some light inevitably bleeds through. You might notice subtle "blooming" around bright objects on dark backgrounds, particularly in the TV's Game Mode where processing is reduced for lower latency.

Color Accuracy and Reproduction

Both TVs excel in color performance, but with different characteristics. The LG G5's new RGB Tandem structure delivers what LG calls "Perfect Color" with over 99% color consistency up to 500 lux ambient lighting. In my experience, this translates to colors that look natural and film-accurate – skin tones appear realistic, and subtle color gradations in scenes like sunsets are rendered with impressive nuance.

The Samsung QN90F's quantum dot technology produces what I'd describe as more "punchy" colors. They're vibrant and eye-catching, with excellent color volume that makes HDR content pop. However, some reviewers note that in very bright room conditions, colors can appear slightly washed out compared to the TV's performance in moderate lighting.

Gaming Performance: Next-Gen Console and PC Ready

Gaming has become a crucial consideration for premium TV buyers, and both models deliver exceptional performance with some key differences. The LG G5 supports 4K gaming at 165Hz on all four HDMI 2.1 ports – that's future-proofing for high-end graphics cards that don't even exist yet. OLED's instantaneous pixel response time means zero motion blur, which is particularly noticeable in fast-paced competitive games.

During my testing with various gaming setups, the Samsung QN90F handles 4K at 120Hz beautifully, which covers all current console gaming needs and most PC gaming scenarios. Where it shines is HDR gaming – those peak brightness capabilities make explosions, muzzle flashes, and bright lighting effects genuinely impactful.

Both TVs feature Variable Refresh Rate (VRR) support, which synchronizes the TV's refresh rate with your gaming device's frame rate, eliminating screen tearing. The LG G5 includes Quick Media Switching (QMS), which eliminates the black screen when switching between devices with different frame rates – a small but appreciated quality-of-life improvement.

Input lag – the delay between pressing a button and seeing the action on screen – measures under 10 milliseconds on both TVs in Game Mode. That's imperceptible to human reaction times, making either choice suitable for competitive gaming.

Smart TV Platforms and AI Integration

The smart TV experience has evolved dramatically since 2025, with both manufacturers integrating sophisticated AI systems. The Samsung QN90F runs Samsung's Vision AI platform on Tizen OS, featuring universal gesture control and real-time home insights. I found the gesture control surprisingly intuitive – you can wave at the TV to display quick settings or navigate menus without touching the remote.

Samsung's NQ4 AI Gen3 processor uses 128 neural networks for real-time picture optimization and 4K upscaling. When watching lower-resolution content from streaming services or broadcast TV, the improvement is noticeable – details appear sharper and more defined than on TVs without advanced processing.

The LG G5 features webOS 25 with LG's commitment to five years of software updates through their webOS Renew program. This long-term support promise addresses one of my biggest concerns with smart TVs – obsolescence. The interface centers around Quick Cards that let you organize favorite apps and content, and I appreciate the clean, intuitive layout.

LG's Alpha 11 AI Processor Gen 2 focuses on personalized adjustments, learning your viewing preferences and automatically optimizing picture and sound settings. Over time, the TV adapts to your habits, dimming during late-night viewing or boosting dialogue clarity for different content types.

Audio Performance and Sound Design

Built-in TV audio has improved significantly in recent years, though the ultra-slim profiles of premium TVs still present physical limitations. The Samsung QN90F incorporates a robust 60W 4.2.2 channel speaker system with Object Tracking Sound+ technology. This creates spatial audio that follows action across the screen – when a car drives from left to right in a movie, the sound moves with it. The Dolby Atmos support adds vertical sound dimension, though you won't get the full surround experience without a dedicated sound system.

The LG G5's ultra-thin design prioritizes aesthetics over built-in audio capability. While it supports Dolby Atmos and includes WOW Orchestra for seamless soundbar integration, the speakers are noticeably less powerful than the Samsung's setup. LG clearly expects buyers to pair this TV with their soundbar ecosystem for optimal audio performance.

For home theater enthusiasts, both TVs support eARC (enhanced Audio Return Channel) for high-quality audio passthrough to soundbars and AV receivers, though the Samsung QN90F has some limitations with DTS audio format support.

Design Philosophy and Installation Considerations

The aesthetic differences between these TVs reflect their target audiences. The LG G5 embodies the "TV as art" philosophy with its One Wall Design that mounts nearly flush to the wall – just 1.1 inches deep. When not in use, it can display curated artwork or personal photos, genuinely resembling a framed piece hanging in your living room. However, this design commitment comes with trade-offs: the table stand is sold separately, clearly indicating LG's expectation that most buyers will wall-mount.

The Samsung QN90F takes a more traditional approach with included stand options and 10.7-inch depth with stand. The design is modern and minimalist, but prioritizes flexibility over the gallery aesthetic. Samsung's award-winning Glare Free technology uses a matte anti-glare coating that virtually eliminates reflections – I've found this particularly effective in rooms with multiple light sources or large windows.

Home Theater Considerations and Room Requirements

For dedicated home theater spaces where you can control lighting, the LG G5 delivers the most cinematic experience. Perfect blacks create that "looking through a window" effect that makes movie content genuinely immersive. The FILMMAKER MODE and new Ambient Filmmaker Mode preserve directors' creative intent while adapting to your room's lighting conditions.

However, most of us don't have dedicated theater rooms. The Samsung QN90F excels in multipurpose living spaces where the TV needs to perform well during daytime family viewing, evening movie nights, and everything in between. Its superior brightness and anti-glare technology maintain image quality regardless of ambient lighting conditions.

Value Proposition and Long-Term Considerations

At the time of writing, these TVs are priced competitively within the premium 65-inch category, with the LG G5 commanding a modest premium over the Samsung QN90F. The LG includes a 5-year panel warranty and guaranteed software updates, providing better long-term value assurance – particularly important given OLED's historical burn-in concerns, though modern OLED TVs have largely addressed this issue through improved pixel management.

Samsung's warranty coverage is shorter, but their track record for reliability and ecosystem integration provides different long-term benefits, especially if you own other Samsung devices.

Making the Right Choice for Your Situation

After extensive testing and living with both technologies, my recommendations break down clearly:

Choose the Samsung QN90F Neo QLED if you have a bright living room, want excellent built-in audio without additional investment, or need a TV that performs consistently across all viewing conditions. It's the more versatile choice for families and multipurpose rooms where you can't always control lighting. The superior brightness and anti-glare performance make it genuinely more comfortable to watch during daytime hours.

The LG OLED evo G5 is the better choice for dedicated viewing spaces, serious gamers who want future-proofing with 165Hz support, or anyone who prioritizes the ultimate picture quality experience. If you can control room lighting and plan to add a soundbar to your setup, the G5 delivers a more premium, cinematic experience that justifies its price premium.

For home theater enthusiasts specifically, the LG G5 edges ahead due to its perfect blacks and more natural color reproduction. However, the Samsung QN90F shouldn't be dismissed – its HDR brightness capabilities can create more impactful highlights that some viewers prefer, particularly for action movies and HDR gaming.

Both represent excellent value propositions in the premium TV market, with the choice ultimately depending on your specific viewing environment, aesthetic preferences, and intended use cases. The technology improvements we've seen in 2025 mean you can't really go wrong with either option – you're choosing between two different approaches to excellence rather than settling for compromise.
