Samsung QN80F vs LG OLED G5: Which Premium 65" TV Should You Buy in 2025?

Shopping for a premium 65-inch TV can feel overwhelming, especially when you're comparing two completely different display technologies. The Samsung QN80F Neo QLED and LG OLED evo G5 both launched in 2025, representing the latest advances in their respective technologies. But here's the thing: they take fundamentally different approaches to creating stunning picture quality, which means one might be perfect for your setup while the other could be a disappointment.

Let me break down everything you need to know to make the right choice for your home.

Understanding the Technology Battle: Mini-LED vs OLED

Before diving into specifics, it's crucial to understand what makes these TVs tick. The Samsung QN80F uses Mini-LED LCD technology – think of thousands of tiny LED lights behind an LCD panel, organized into zones that can dim independently. This is called "full array local dimming" (FALD), and it's a major upgrade from traditional edge-lit TVs where LEDs only line the edges of the screen.

The LG G5, on the other hand, uses OLED technology, which stands for Organic Light Emitting Diode. Here's where it gets interesting: each pixel is its own light source. When a pixel needs to be black, it simply turns off completely. No backlight bleeding, no compromise – just perfect darkness.

Both technologies have evolved significantly in 2025. Samsung's Neo QLED lineup now includes more sophisticated Quantum Matrix Technology, which gives even finer control over those mini-LED zones. Meanwhile, LG's new 4-Stack RGB Tandem OLED panel addresses OLED's traditional weakness – brightness – by layering the light-emitting materials to achieve up to 45% brighter images than previous generations.

Picture Quality: The Heart of the Matter

Contrast and Black Levels

This is where the fundamental differences become clear. The LG G5 achieves what we call "infinite contrast" because its pixels can turn completely off. When you're watching a movie with a starfield, those black areas are truly black – no light whatsoever. It's genuinely stunning, especially in a darkened room.

The Samsung QN80F, despite having impressive local dimming with hundreds of zones, still uses a backlight that shines through an LCD panel. This means blacks appear as very dark gray rather than true black. However, Samsung's Quantum Matrix Technology has narrowed this gap considerably, and most viewers won't notice the difference in normally lit rooms.

Brightness and HDR Performance

Here's where things flip. The Samsung QN80F can get significantly brighter than traditional OLEDs, making it exceptional for HDR (High Dynamic Range) content in bright rooms. HDR is essentially a way of displaying a wider range of brightness and color, making images look more lifelike. When HDR content has bright explosions, sunlight, or reflections, the Samsung really shines – literally.

The LG G5 fights back with its new Brightness Booster Ultimate technology. While previous OLEDs struggled in bright rooms, this model can hold its own, though it still doesn't quite match the peak brightness of Mini-LED displays. However, what's impressive is how it maintains perfect blacks even while boosting brightness – something LCD technology simply cannot do.

Color Accuracy and Volume

Both TVs excel here, but in different ways. The Samsung QN80F uses Quantum Dot technology, which essentially means tiny nanocrystals that produce very pure colors when hit with light. This creates exceptionally vibrant and accurate colors, especially reds and greens.

The LG G5 takes a different approach with its 4-Stack RGB Tandem structure. By layering the color-producing elements, it achieves better color purity and can display a wider range of colors while maintaining brightness. The result is colors that pop without looking artificial – something OLED has always done well.

Gaming Performance: Where Refresh Rates Rule

Gaming has become a crucial consideration for TV buyers, and both models deliver here. The Samsung QN80F supports up to 4K at 144Hz, which means games can display 144 frames per second at full 4K resolution. That's incredibly smooth, especially for fast-paced games like racing or first-person shooters.

But the LG G5 goes even further, supporting 4K at 165Hz – the highest refresh rate available in consumer TVs as of 2025. More importantly, it includes advanced VRR (Variable Refresh Rate) features like QMS (Quick Media Switching), which eliminates those annoying black screens when your gaming device changes frame rates.

Both TVs include ALLM (Auto Low Latency Mode), which automatically switches to a gaming mode when it detects a gaming console. Input lag – the delay between pressing a button and seeing the action on screen – is extremely low on both, typically under 10 milliseconds.

If you're a serious PC gamer with a high-end graphics card, the LG G5 has the edge. Console gamers will be perfectly happy with either, though the Samsung offers better value for gaming performance.

Smart Features and User Experience

Smart TV interfaces have come a long way, and both manufacturers have made significant improvements in 2025. The Samsung QN80F runs Tizen OS with Samsung's new Vision AI suite. This includes features like Live Translate for real-time subtitle translation and Generative Wallpaper that creates custom art using AI.

The LG G5 uses webOS 25, which I find more intuitive than Samsung's interface. LG's Quick Cards system lets you organize your favorite apps and content in a way that actually makes sense. More importantly, LG promises 5 years of webOS updates, which is longer than most manufacturers commit to. This means your TV will stay current with new streaming services and features much longer.

Both TVs include comprehensive voice control – Bixby for Samsung, and multiple options including Alexa and Google Assistant for LG. The LG G5 also includes an AI button on its Magic Remote that makes voice commands more accessible.

Design and Build Quality

This is where the LG G5 really sets itself apart. Its One Wall Design lets it mount completely flush against the wall, looking more like a piece of art than a traditional TV. When you're not watching, it can display artwork or photos through its gallery mode. The build quality feels genuinely premium, with materials that justify the higher price point.

The Samsung QN80F looks good but takes a more traditional approach. It's well-built and will look great in most living rooms, but it doesn't have that "wow factor" of the ultra-thin OLED design.

Room Lighting: The Deciding Factor

This might be the most important consideration. If your TV room gets a lot of natural light – big windows, bright overhead lighting – the Samsung QN80F will likely give you a better experience. Its higher peak brightness and improved anti-glare coating mean you won't be squinting to see dark scenes during the day.

In a dedicated home theater or family room where you can control the lighting, the LG G5 creates a more immersive experience. Those perfect blacks make movie night feel cinematic in a way that LCD technology, despite its improvements, still can't quite match.

Value Considerations

At the time of writing, there's a significant price difference between these models. The Samsung QN80F positions itself as a premium TV with flagship features at a more accessible price point. You're getting excellent picture quality, strong gaming features, and solid smart TV capabilities without paying the absolute premium.

The LG G5 commands a higher price but includes several justifications: the latest OLED technology, superior design, longer software support commitment, and that 5-year panel warranty. OLED panels historically had concerns about burn-in (permanent image retention), but modern OLEDs like the G5 include multiple protection mechanisms that make this much less of a worry.

Home Theater Considerations

If you're building a dedicated home theater, several factors become more important. The LG G5 excels here because you can control the lighting. Those perfect blacks create an immersive experience that's hard to match. The flush wall mounting also creates a cleaner, more professional look.

For audio, both TVs support Dolby Atmos, but you'll likely want to add a soundbar or surround sound system for true theater experience. The LG G5 has better integration with LG's soundbars through WOW Orchestra, which coordinates the TV's speakers with the soundbar for fuller sound.

Long-term Ownership

Here's something many buyers don't consider enough: how will this TV age? The Samsung QN80F uses mature LCD technology that's proven reliable. You don't need to worry about burn-in, and the backlight system should last many years.

The LG G5 includes multiple burn-in prevention features, but OLED panels do gradually dim over time – typically over many years of heavy use. However, LG's extended warranty shows confidence in their panel longevity, and most users won't notice degradation during normal ownership.

Both TVs should receive software updates for several years, but LG's specific 5-year commitment gives it an edge for staying current with new streaming services and features.

Who Should Choose Which TV?

Choose the Samsung QN80F if:

• Your viewing room gets lots of natural light
• You want flagship features without paying the absolute premium
• Gaming is important but you don't need the absolute highest refresh rates
• You prefer worry-free ownership without burn-in concerns
• You watch a lot of HDR content and want maximum brightness

Choose the LG G5 if:

• Picture quality is your absolute top priority

The Bottom Line

Both the Samsung QN80F and LG G5 are excellent TVs that represent the best of their respective technologies in 2025. The Samsung delivers flagship performance at a more accessible price point, making it ideal for bright rooms and value-conscious buyers who don't want to compromise on features.

The LG justifies its premium pricing with cutting-edge OLED technology, superior design, and features that will keep it current for years to come. In a darkened room, it simply creates a more immersive viewing experience.

Your room's lighting conditions and budget will likely make the decision for you. But whichever you choose, you'll be getting one of the best TVs available in 2025 – just optimized for different viewing environments and priorities.
