Samsung Q7F vs LG G5 OLED: Which 65" 4K TV Should You Buy in 2025?

The 65-inch 4K TV market has never been more exciting—or confusing. With Samsung's Q7F QLED offering impressive smart features at a budget-friendly price and LG's OLED evo G5 pushing the boundaries of display technology, choosing between them isn't just about picking a TV—it's about deciding what kind of viewing experience matters most to you.

Both TVs launched in March 2025, but they represent completely different philosophies. The Samsung Q7F focuses on delivering maximum value with AI-powered features that make your TV smarter, while the LG G5 OLED introduces revolutionary display technology that fundamentally changes how we think about picture quality. At the time of writing, there's roughly a $1,800 price difference between them, which tells you everything about their intended markets.

Understanding Display Technologies: QLED vs OLED

Before diving into specifics, it's crucial to understand what sets these TVs apart at the most basic level. The Samsung Q7F uses QLED (Quantum Dot Light Emitting Diode) technology, which is essentially a very sophisticated LED TV. It starts with a traditional LED backlight, then adds a layer of quantum dots—microscopic particles that convert blue light into precise red and green wavelengths. This creates more accurate colors and better brightness than standard LED TVs.

The LG G5 OLED takes a completely different approach. OLED (Organic Light Emitting Diode) panels don't need a backlight at all. Each of the 8.3 million pixels produces its own light and can turn completely off to create perfect black. This year's G5 is particularly special because it's the first TV to use LG's new 4-Stack RGB Tandem panel, which layers four OLED emission layers instead of the traditional single layer, dramatically boosting brightness while maintaining perfect blacks.

Think of it this way: QLED is like having millions of tiny colored filters in front of a powerful flashlight, while OLED is like having millions of individual light bulbs that can each turn on, off, or dim independently.

Picture Quality: Where the Real Differences Live

When it comes to picture quality, the differences between these TVs are immediately apparent. The LG G5 OLED delivers what can only be described as a transformative viewing experience. Those perfect blacks aren't just a spec sheet bullet point—they create contrast that makes images appear three-dimensional. When you're watching a space movie and see stars against the void, the LG G5 literally turns off those black pixels, creating infinite contrast that no LED-based display can match.

The new RGB Tandem panel in the LG G5 addresses OLED's traditional weakness: brightness. Previous OLED TVs struggled in bright rooms, but this model delivers up to 45% more brightness than its predecessors. In practical terms, HDR (High Dynamic Range) content—those ultra-bright highlights in movies and shows—now pops with intensity that rivals the brightest LED TVs while maintaining perfect shadow detail.

The Samsung Q7F, however, shouldn't be underestimated. Its Quantum Dot technology, certified as a Real Quantum Dot Display, produces exceptionally vibrant colors with 100% Color Volume. This means it can display accurate colors even at extreme brightness levels, something that matters when you're watching in a sunlit living room. The 500 cd/m² peak brightness and Pantone-certified color accuracy ensure consistent, reliable performance across different lighting conditions.

For home theater enthusiasts, the LG G5 OLED is the clear winner. The combination of perfect blacks, infinite contrast, and Dolby Vision HDR support creates a cinematic experience that's hard to match. The improved brightness means you don't need to dim the lights as much as with previous OLED models, making it more practical for mixed-use spaces.

Gaming Performance: A Tale of Two Generations

Gaming performance reveals perhaps the starkest difference between these TVs. The Samsung Q7F offers competent gaming features with Auto Game Mode and Motion Xcelerator technology, but it's fundamentally limited by its 60Hz refresh rate. This means it can display a maximum of 60 frames per second, which is fine for console gaming but limiting for high-end PC gaming or future gaming systems.

The LG G5 OLED is in a completely different league. It supports 4K resolution at up to 165Hz refresh rate on all four HDMI 2.1 ports, making it one of the most capable gaming displays available. The input lag measures just 4 milliseconds at 165Hz—that's faster than many dedicated gaming monitors. Variable Refresh Rate (VRR) technology synchronizes the display's refresh rate with your gaming system's frame rate, eliminating screen tearing and stuttering.

For competitive gamers, the LG G5's nearly instantaneous response time means moving objects appear sharp without the blur that can affect gameplay. The self-emissive OLED pixels can change states almost instantly, unlike LED TVs that rely on liquid crystals that take time to rotate.

If you're primarily a casual console gamer, the Samsung Q7F will serve you well. But if you're serious about gaming—whether competitive multiplayer or immersive single-player experiences—the LG G5 OLED offers capabilities that justify its premium positioning.

Smart Features and AI: Different Approaches to Intelligence

Both TVs showcase impressive AI capabilities, but with distinct approaches. The Samsung Q7F features Vision AI, which feels more like having a smart assistant built into your TV. It can generate AI-created wallpapers that match your mood or room's ambiance, provide real-time translation for foreign content, and respond to gesture controls. The Tizen platform integrates seamlessly with Samsung's SmartThings ecosystem, making it particularly appealing if you already use Samsung appliances or devices.

The LG G5 OLED takes a more refined approach with webOS 25 and the Alpha 11 AI Processor Gen 2. Rather than flashy AI features, it focuses on intelligent picture and sound optimization. The AI analyzes what you're watching in real-time, adjusting settings for optimal performance. Quick Cards organize your favorite apps intelligently, and the Magic Remote with its AI button makes navigation intuitive.

What sets LG apart is their webOS Renew program, which guarantees software updates and new features for five years. This long-term support commitment is rare in the TV industry and adds significant value to your investment.

Audio Capabilities: Beyond the Speakers

Neither TV will blow you away with built-in audio—that's just the reality of modern slim displays. The Samsung Q7F includes Object Tracking Sound Lite, which attempts to move audio effects across the screen to match on-screen action, and its 20W, 2-channel speakers are adequate for basic viewing.

The LG G5 OLED benefits from more sophisticated audio processing thanks to its powerful Alpha 11 chip. While specific audio specs aren't dramatically different, the advanced processing creates a more refined soundstage. Both TVs support Dolby Atmos and work well with their respective manufacturers' soundbars through Q-Symphony (Samsung) and WOW Orchestra (LG) technologies.

For serious home theater use, you'll want to pair either TV with a quality soundbar or surround sound system. The processing power advantage of the LG G5 does provide better foundation for audio enhancement, but both will benefit significantly from external audio solutions.

Build Quality and Design Philosophy

The design differences reflect each TV's market positioning. The Samsung Q7F focuses on practical flexibility with adjustable stand legs that can be positioned at different widths (40.4" or 12") to accommodate various furniture setups. It's a thoughtful touch that shows Samsung's attention to real-world usage scenarios.

The LG G5 OLED embraces its premium positioning with the "One Wall Design" that mounts flush against the wall like a piece of art. When not in use, it can display artwork or personal photos, blending into your living space. The ultra-thin profile (2.4" depth) creates a stunning visual impact that emphasizes the TV as a design element, not just an electronic device.

Build quality reflects the price difference. The Samsung Q7F feels solid and well-constructed for its price point, while the LG G5 OLED exhibits the premium materials and attention to detail you'd expect from a flagship product. The LG G5 also includes a 5-year panel warranty, demonstrating LG's confidence in their OLED technology's longevity.
