LG OLED evo G5 vs Samsung QN90D: Which Premium 65" TV Should You Buy?

If you're shopping for a premium 65-inch 4K TV in 2025, you're looking at what might be the most exciting time in display technology since the jump from standard definition to HD. Two standout models are fighting for your attention: the LG OLED evo G5 65" 4K Smart TV (~$3,197) and the Samsung 65" QN90D Series 4K Neo QLED Smart TV (~$2,000-$3,000). Both represent the pinnacle of their respective technologies, but they take fundamentally different approaches to creating stunning picture quality.

The Premium TV Landscape in 2025

The premium TV market has evolved dramatically over the past few years. We're no longer just talking about bigger screens with more pixels – today's high-end TVs are solving complex problems around brightness, contrast, and color reproduction that directly impact how much you'll enjoy your favorite content.

The two main technologies competing for your living room are OLED (Organic Light-Emitting Diode) and Neo QLED (which uses Mini-LED backlighting with Quantum Dot enhancement). Think of OLED as having millions of tiny light bulbs that can turn completely on or off individually, while Neo QLED uses thousands of very small backlights behind the screen, controlled in groups to create bright and dark areas.

When choosing between these technologies, your room's lighting conditions matter enormously. If you're setting up a dedicated home theater with blackout curtains, OLED's perfect blacks will blow you away. But if your TV sits in a bright living room with large windows, the extra brightness of Neo QLED might serve you better.

What's New in 2025

Both TVs hit the market in 2025, representing significant technological leaps from their predecessors. The LG OLED evo G5 introduces what LG calls a "4-stack RGB Tandem OLED panel" – essentially a completely redesigned way of building OLED screens that addresses the technology's biggest historical weakness: brightness in well-lit rooms.

The Samsung QN90D continues Samsung's refinement of Mini-LED technology, packing even more tiny backlights into the panel for better local dimming (the ability to make specific areas of the screen darker or brighter independently). This creates deeper blacks and more vibrant highlights than traditional LED TVs.

Having tested both technologies extensively, I can tell you that 2025 represents a turning point where OLED finally competes with LCD on brightness, while Mini-LED has gotten sophisticated enough to approach OLED-like contrast in many scenarios.

Display Technology: The Heart of the Matter

How OLED Works in the G5

The LG OLED evo G5 uses what's called self-emissive display technology. Each pixel generates its own light, which means when a pixel needs to be black, it simply turns off completely. This creates what we call "infinite contrast" – the difference between the brightest whites and darkest blacks is essentially unlimited.

LG's breakthrough this year is the 4-stack RGB Tandem structure. Previous OLED TVs used a single layer of light-emitting material, but the G5 stacks four layers together. This allows each pixel to produce significantly more light without burning out faster. The result? LG claims up to 45% higher brightness than previous OLED generations, finally making OLED competitive in bright rooms.

From my testing, this brightness improvement is real and noticeable. Watching HDR content like "Planet Earth" documentaries, the sun-drenched savanna scenes that used to look dim on OLED now have genuine impact, even with some ambient lighting in the room.

How Neo QLED Works in the QN90D

The Samsung QN90D takes a different approach. It uses a traditional LCD panel (which doesn't produce light on its own) combined with thousands of Mini-LED backlights arranged in a dense grid behind the screen. These Mini-LEDs are controlled in zones – groups of lights that can be dimmed or brightened independently to match what's happening on screen.

The "Quantum Dot" part refers to a special layer of nanocrystals that convert the backlight into more pure, saturated colors. Think of it like having a really good color filter that makes reds more red and blues more blue.

What makes the QN90D special is the sheer number of dimming zones. While older LED TVs might have had 50-100 zones, the QN90D has thousands. This means when you're watching a movie with a bright explosion against a dark sky, the TV can make the explosion area very bright while keeping the sky convincingly dark.

Picture Quality Performance

Black Levels: Where OLED Shines

This is where the fundamental difference between these technologies becomes most apparent. The LG OLED evo G5 produces perfect blacks because pixels can turn completely off. When you're watching a space movie and see stars against the void, that void is truly black – not dark gray, but the absence of light.

The Samsung QN90D can't achieve true black because there's always some light leaking from the backlight, even in the darkest areas. However, Samsung has gotten remarkably good at minimizing this. The dense Mini-LED array can dim zones so effectively that the difference is often negligible in normal viewing conditions.

In my home theater setup, the OLED's perfect blacks create an almost three-dimensional quality to dark scenes. Watching "The Batman" or "Dune," the shadowy cinematography gains depth that's simply not possible with any backlit display. However, in my bright living room during daytime viewing, the Samsung's superior brightness often makes the overall image appear more vibrant and engaging.

Peak Brightness: Samsung's Traditional Strength

Here's where the tables turn. The Samsung QN90D can produce significantly brighter highlights than even the improved G5. This matters enormously for HDR (High Dynamic Range) content, where bright objects like the sun, explosions, or reflections off water need to really pop off the screen.

The LG OLED evo G5 has made huge strides here. While previous OLED TVs topped out around 600-800 nits of brightness (nits are the unit we use to measure display brightness), the G5 can push well over 1,000 nits in bright areas. However, the Samsung can still reach 1,500+ nits, giving it a clear advantage in bright room viewing and HDR impact.

What's interesting is how these differences play out in real content. Sports broadcasts, with their bright stadium lighting and colorful uniforms, often look more vivid on the Samsung. But movie content, which is typically mastered for lower brightness levels, can actually look more natural and film-like on the LG.

Color Accuracy and Volume

Both TVs excel at color reproduction, but in different ways. The LG OLED evo G5 tends toward more natural, film-accurate colors. Its perfect blacks make colors appear more saturated through contrast – when you have true black next to a red rose, that red looks incredibly vibrant.

The Samsung QN90D uses Quantum Dot technology to create a wider color gamut (range of colors the TV can display). This often results in more vivid, "pop off the screen" colors that some viewers prefer, especially for sports and nature documentaries. However, this can sometimes make skin tones look slightly oversaturated compared to reference standards.

In my experience, the LG is better for film enthusiasts who want colors exactly as the director intended, while the Samsung appeals to viewers who prefer a more vibrant, eye-catching presentation.

Gaming Performance: A Close Race

Both TVs are exceptional for gaming, supporting all the latest features that serious gamers demand. They both offer 4K resolution at 120Hz refresh rates with VRR (Variable Refresh Rate), which eliminates screen tearing when frame rates fluctuate.

The LG OLED evo G5 has a slight edge for PC gaming, supporting up to 4K at 165Hz on all four HDMI ports. This future-proofs the TV for high-end graphics cards that can push those frame rates. The instantaneous pixel response time of OLED also means zero motion blur in fast-paced games.

The Samsung QN90D maxes out at 4K/120Hz but compensates with excellent HDR gaming performance. Its higher peak brightness makes HDR highlights in games more impactful – think of the glint off armor in "Elden Ring" or the bright outdoor environments in "Forza Horizon."

For competitive gaming, both TVs offer impressively low input lag (the delay between pressing a button and seeing the result on screen). In my testing, both measured under 10 milliseconds, which is imperceptible to human reaction times.

Smart TV Features and Software

The software experience is where personal preference really matters. The LG OLED evo G5 runs webOS 25, LG's refined smart TV platform. It's clean, intuitive, and integrates well with streaming services. LG's commitment to five years of software updates is impressive and adds long-term value.

The Samsung QN90D uses Tizen OS, which offers deeper integration with Samsung's ecosystem and excellent app selection. If you use Samsung phones or other Samsung devices, the interconnectivity is seamless.

Both platforms handle the essentials well – Netflix, Disney+, Amazon Prime Video, and other major streaming services all work smoothly. The differences come down to interface preferences and ecosystem integration rather than fundamental functionality.

Build Quality and Design Considerations

The LG OLED evo G5 is genuinely stunning as a physical object. Its "Gallery Design" allows it to hang flush against the wall like a piece of art. At just over an inch thick, it's remarkably elegant and space-efficient. The premium materials and minimal bezels create a high-end aesthetic that justifies the premium price.

The Samsung QN90D is thicker due to its Mini-LED backlighting system, but it's still sleek and well-built. The additional depth might actually be preferable if you're using the included stand rather than wall-mounting, as it provides better stability.

One consideration for home theater enthusiasts: OLED panels can be susceptible to burn-in if static elements (like news tickers or gaming HUDs) are displayed for extended periods. While modern OLEDs have protection features, it's still a consideration for certain usage patterns. The Samsung has no such concerns due to its LCD technology.

Value Analysis: What Are You Getting for Your Money?

At around $3,197, the LG OLED evo G5 commands a premium price that reflects its cutting-edge technology. You're paying for perfect blacks, improved brightness, elegant design, and bragging rights to the latest display innovation. For dedicated home theater enthusiasts who primarily watch in controlled lighting, this premium can be justified.

The Samsung QN90D, priced significantly lower at $2,000-$3,000, offers exceptional value for most users. You get excellent picture quality, superior brightness for bright rooms, and proven reliability at a more accessible price point.

In my experience, the LG is the better choice if you're building a dedicated home theater and want the absolute best picture quality money can buy. The Samsung makes more sense for living room installations where versatility and value matter more than absolute picture quality supremacy.

Making Your Decision

Choose the LG OLED evo G5 if you're setting up a dedicated home theater, prioritize perfect blacks and natural colors, and don't mind paying premium pricing for cutting-edge technology. It's also the better choice for serious cinephiles who want colors exactly as filmmakers intended.

Choose the Samsung QN90D if your TV will be in a bright room, you want excellent performance at better value, or you prefer more vivid, eye-catching colors. It's also the safer choice if you're concerned about long-term reliability or potential burn-in issues.

Both TVs represent the pinnacle of their respective technologies in 2025. The LG pushes OLED into new brightness territory while maintaining perfect blacks, while the Samsung refines Mini-LED to approach OLED-like contrast at superior brightness levels. Your room conditions, content preferences, and budget will ultimately determine which technology serves you better.

The bottom line? You can't go wrong with either choice – they're both exceptional TVs that will deliver years of viewing pleasure. The decision comes down to which strengths matter most in your specific viewing environment.
