Samsung QN90F vs LG G5 In Depth Comparison
After weeks of switching between the Samsung QN90F and LG G5 in my living room, I can honestly say this matchup feels like two different philosophies clashing head-on. One is a bright, bold Mini LED beast built for everyday real-world viewing, while the other is a sleek OLED that disappears into the wall and delivers cinema-like depth. I tested both during bright afternoons with sunlight streaming in, late-night movie marathons, intense gaming sessions, and casual streaming. The Samsung QN90F vs LG G5 In Depth Comparison isn’t just about checking boxes on a spec sheet—it’s about how these TVs actually perform when the lights are on and life is happening around them. Samsung’s Neo QLED approach shines in larger spaces and brighter rooms, while LG’s OLED evo G5 focuses on pure contrast and effortless elegance. Let’s break it down step by step so you can decide which one fits your setup.
Picture Quality: Mini LED Brightness Meets OLED Perfection
Picture quality is where the real battle happens, and the differences are night and day once you sit down with both TVs side by side. The Samsung QN90F uses Quantum Mini LED backlighting paired with Quantum Matrix Technology Pro. This means thousands of tiny LEDs working together with precise local dimming zones. In practice, it gets incredibly bright—perfect for my sunlit living room where afternoon glare used to wash out other screens. Colors pop thanks to Color Booster Pro, and the NQ4 AI Gen3 Processor (or NQ8 on the massive 115-inch version) handles 4K AI Upscaling Pro beautifully. Even older 1080p content looks sharp and detailed without that artificial “plastic” look you sometimes see on lesser processors. The Glare Free coating is a game-changer; I could watch football with the curtains open and never lose detail in highlights.
Flip to the LG G5 and you’re stepping into OLED territory with Brightness Booster Ultimate and the α11 AI Processor 4K Gen2. Every pixel lights itself, so blacks are truly black—no blooming or haloing around bright objects like you might notice on the Samsung during very dark scenes. Dolby Vision support gives HDR movies an extra layer of dynamic tone mapping that feels more cinematic. Response time is under 0.1ms, which makes motion feel instant. However, in my bright room tests, the LG had to work harder to fight reflections, and peak brightness, while impressive for an OLED, still can’t match the Samsung’s Mini LED punch during daytime sports or gaming. Both handle 120Hz native refresh with VRR up to 165Hz, so fast action stays smooth, but the Samsung’s Motion Xcelerator 165Hz felt slightly more forgiving with content that isn’t perfectly mastered. If your room gets a lot of light or you have a huge wall, the QN90F wins for punch and clarity. For a dark media room where contrast is king, the G5’s infinite blacks and Filmmaker Mode deliver that “wow” factor that makes you forget you’re watching a TV.
Audio Performance: Power, Clarity, and Immersive Sound
Sound often gets overlooked until you actually use the TV without a soundbar, and here both sets punch above their size but in different ways. The Samsung QN90F packs a 60W 4.2.2 channel system with Object Tracking Sound+ and Dolby Atmos. In real-life use, voices stay crystal clear thanks to Active Voice Amplifier Pro—even when the kids are playing in the background. The sound follows on-screen action, so during a car chase scene the roar moves across the room instead of staying stuck in the center. I tested it at moderate volumes in a 15x20-foot living room and it filled the space without distortion. The built-in speakers integrate nicely with SmartThings if you expand the system later.
The LG G5 counters with a 4.2 channel setup boosted by AI Sound Pro that creates a virtual 11.1.2 experience through Dolby Atmos. It sounds surprisingly wide and tall for a thin OLED panel. Movie dialogue felt more natural to my ears, and the virtual height channels made overhead effects in action films feel genuinely immersive. However, at higher volumes the Samsung’s extra wattage gave it more authority for music and sports broadcasts. Both support Dolby Atmos, but the LG’s AI processing seemed to adapt better to different content types automatically—switching from a quiet drama to a loud concert felt seamless. If you plan to use the TV speakers most of the time, the Samsung edges it for raw power and room-filling presence. Pair either with a soundbar and the difference shrinks, but out of the box the QN90F feels more robust for larger families or open-plan spaces.
Smart Features and Daily Usability: Tizen vs webOS in Real Life
Day-to-day operation is where personality really shows, and I spent hours flipping between apps, voice commands, and smart home controls. Samsung’s Tizen platform on the QN90F is lightning fast with a clean interface. The Gaming Hub loads instantly, and SmartThings hub integration means I could control lights, thermostat, and even the fridge from the same remote. Bixby and Alexa work well, though I mostly used the SolarCell remote that charges itself in light—no batteries ever needed. The 4 HDMI ports and 2 USBs handled all my devices without fuss, and Wi-Fi 5 was stable enough for 4K streaming.
LG’s webOS 25 on the G5 feels more intuitive and modern. The Magic Remote is a joy—point and click like a mouse, and it never gets lost thanks to the pointer. Google Assistant and Alexa are both built in, plus Apple AirPlay 2 and Google Cast make mirroring effortless. Three USB ports give a slight edge for external storage, and Wi-Fi 6E delivered faster downloads during firmware updates. Both TVs have excellent AI upscaling and auto HDR remastering, but LG’s Dynamic Tone Mapping Pro felt more refined for mixed content. In my testing, webOS had fewer menu layers to reach settings, while Tizen excelled at quick app switching. Neither lagged, but if you live in an Apple or Google ecosystem, the LG integrates more smoothly. For Samsung loyalists who already use SmartThings, the QN90F feels like home right away.
Gaming Capabilities: Serious Play on Both Panels
Gamers will be happy with either TV, but the strengths lean in slightly different directions. The Samsung QN90F offers FreeSync Premium Pro, VRR, a dedicated Game Bar, and AI Auto Game Mode that instantly optimizes settings when it detects a console or PC. Input lag is low enough that competitive titles felt responsive, and the 165Hz capability keeps everything buttery smooth. The larger size options (up to 115 inches) make it a dream for immersive setups—I tried it with a PS5 and the scale was ridiculous in a good way.
The LG G5 brings NVIDIA G-Sync, AMD FreeSync Premium, ALLM, and that sub-0.1ms response time that makes fast-paced shooters feel instantaneous. Four full HDMI 2.1 ports mean you can hook up multiple next-gen consoles without swapping cables. In my side-by-side tests, both handled 4K 120Hz gaming flawlessly, but the LG’s perfect blacks gave darker games like horror titles an extra edge in atmosphere. The Samsung fought reflections better during daytime sessions. If you game in a bright room or want the biggest screen possible, go Samsung. For pure responsiveness and contrast in a dedicated gaming cave, the G5 is tough to beat. Both include cloud gaming options through their respective hubs, so you’re covered either way.
Real-World User Experiences from Around the World
Living with these two TVs for extended periods taught me more than any spec sheet ever could, and the feedback pouring in from owners across different countries echoes many of my own observations. Families in sunny living rooms in places like California or Dubai rave about the Samsung QN90F's ability to cut through daylight without losing detail. One user in a bright open-plan home mentioned how the Glare Free coating let them watch afternoon games with curtains half-open, something their previous OLED struggled with. The Mini LED brightness feels reliable for daily use—kids' cartoons, news, and sports all look punchy without constant adjustments. However, a few owners in darker setups noted occasional blooming around bright objects in HDR scenes, describing it as "grid-like" halos that pull you out of the movie. Motion handling drew mixed comments too; some reported judder in fast sports or panning shots unless they tweaked the Motion Xcelerator settings carefully.
On the LG G5 side, users in dedicated media rooms or apartments with controlled lighting consistently call it a "game-changer" for movies. The perfect blacks make night scenes in thrillers feel immersive, and the Brightness Booster Ultimate has surprised many who expected traditional OLED limitations. A reviewer in Europe who tested it for months said the colors look more natural and vibrant than last year's models, especially in Dolby Vision content. Gamers from PC and console communities highlight the sub-0.1ms response time and G-Sync support, saying competitive titles feel incredibly responsive. Yet, some early adopters mentioned minor issues like floating blacks in certain HDR10 scenes or slight posterization in dark gradients—problems that firmware updates seem to be addressing for most. Overall, people appreciate the elegant wall-mount design (included in many regions), which makes the TV almost disappear.
Detailed Customer Reviews and Practical Insights
Diving deeper into what actual buyers say after weeks or months of ownership reveals honest strengths and trade-offs. Samsung QN90F owners frequently praise the Tizen platform for its speed and SmartThings integration— one family in Asia mentioned controlling their entire smart home from the SolarCell remote without ever changing batteries. Picture quality gets high marks for bright rooms, with comments like "finally a TV I don't have to fight the sun for." Sound stands out too; the 4.2.2 channel system with Object Tracking Sound+ fills medium-sized rooms surprisingly well, reducing the immediate need for a soundbar. On the flip side, some users found the matte screen made colors appear slightly muted compared to glossy panels, and a handful reported smearing in fast-motion gaming or sports, especially on smaller sizes. A few early complaints about judder or blooming led to returns, but many who calibrated the TV properly ended up satisfied.
LG G5 reviews lean heavily toward picture enthusiasts. Customers highlight the α11 AI Processor's upscaling, noting how even lower-quality streaming looks sharp and clean. The Magic Remote gets love for its pointer functionality, though some newer users say the 2025 version feels less intuitive than previous ones. Brightness surprises everyone—many say it's the first OLED that truly competes in well-lit spaces without washing out. Home theater fans love the Filmmaker Mode and Dolby Vision, describing scenes as "cinematic" with deep, inky blacks. Practical downsides include occasional app freezes in webOS (though rare) and the fact that the pedestal stand isn't always included. A few users in warmer climates mentioned slight heat from the panel during long sessions, but nothing alarming. Gaming feedback is overwhelmingly positive, with low input lag making it a favorite for both casual and serious players.
