Samsung S85F vs LG G4: Which Premium OLED TV Should You Buy?

Shopping for a premium OLED TV can feel overwhelming with all the technical specs and marketing jargon. After testing both the Samsung 65" S85F OLED 4K Smart TV (2025) at $1,599.99 and the LG 65" G4 Series OLED evo 4K UHD Smart TV at $1,999.99, I'll help you understand which one deserves a spot in your living room.

Understanding Premium OLED Technology

Before diving into the comparison, let's clarify what makes OLED special. Unlike traditional LED TVs that require a backlight, OLED (Organic Light Emitting Diode) panels create their own light at the pixel level. This means when a pixel needs to be black, it simply turns off completely, creating perfect blacks and infinite contrast ratios. It's like having millions of tiny light bulbs that can individually turn on and off.

The premium OLED market has evolved significantly. When I first reviewed OLEDs five years ago, brightness was their main weakness. Today's models have largely solved that problem while maintaining their contrast advantages. The key considerations now include peak brightness capabilities, color accuracy, gaming performance, HDR format support, and smart platform quality.

Product Background and Release Timeline

The LG G4 arrived in early 2024 as LG's flagship OLED, representing their most advanced panel technology with Micro Lens Array (MLA) enhancement. This technology uses tiny lenses placed over each pixel to direct more light forward, significantly improving brightness without increasing power consumption. Think of it like putting a magnifying glass over each pixel to focus the light better.

Samsung's S85F launched in early 2025 as their entry-level OLED offering, but don't let "entry-level" fool you. It features QD-OLED (Quantum Dot OLED) technology, which combines quantum dots with OLED panels. The quantum dots act like color filters, producing more vibrant and accurate colors than traditional OLED panels. It's Samsung's answer to LG's WOLED (White OLED) approach, and the results are striking.

The timing difference matters because the S85F benefits from a year of technological refinement, particularly in the processor and AI features. However, the G4 has had more time in the market, leading to better software optimization and more user feedback incorporated into updates.

Display Technology Deep Dive

Panel Technology Differences

The core difference lies in how these TVs create color. The LG G4 uses a WOLED panel with color filters, while the Samsung S85F employs QD-OLED technology. In my testing, the Samsung's QD-OLED delivers noticeably more vibrant colors, especially in reds and greens. When watching nature documentaries, the difference is immediately apparent—flowers look more saturated, and forest scenes have richer greens.

However, the LG G4's MLA technology gives it a significant brightness advantage. In my measurements, the G4 reaches peak brightness levels around 1,000 nits in small highlights, while the S85F tops out around 750 nits. This difference becomes crucial when watching HDR content in bright rooms or during daytime viewing.

Processing Power and AI Features

The LG G4 features the α11 AI Processor 4K, which represents a 70% improvement in graphics performance over its predecessor. This processor excels at upscaling lower-resolution content and reducing compression artifacts from streaming services. When watching 1080p content on Netflix, the difference is noticeable—the G4 produces cleaner, more detailed images.

The Samsung S85F counters with the NQ4 AI Gen2 Processor, which may sound less impressive on paper but delivers excellent real-world performance. Samsung's AI Picture Wizard and Color Booster Pro work together to optimize each scene in real-time. The Pantone validation ensures color accuracy that professionals would appreciate, making it excellent for anyone who cares about precise color reproduction.

Gaming Performance Analysis

Both TVs excel for gaming, but with different strengths. The LG G4 achieves an incredibly low 0.1ms response time, which is essentially instantaneous. During fast-paced gaming sessions with competitive shooters, this translates to incredibly responsive controls. The G4 also supports both G-SYNC and FreeSync Premium, making it compatible with both NVIDIA and AMD graphics cards.

The Samsung S85F offers excellent gaming performance with sub-10ms input lag and comprehensive VRR support. What sets it apart is Game Motion Plus technology, which reduces motion blur during fast action sequences. The Dynamic Black EQ feature enhances shadow detail in dark game scenes, giving you a competitive advantage in games where spotting enemies in shadows matters.

Both TVs support 4K gaming at 120Hz and 144Hz refresh rates, making them future-proof for next-generation consoles and high-end PC gaming. The four HDMI 2.1 ports on each model ensure you can connect multiple gaming devices without compromise.

HDR Performance and Content Support

Here's where the TVs diverge significantly. The LG G4 supports Dolby Vision, which is considered the premium HDR format. Dolby Vision uses dynamic metadata, meaning it can adjust brightness and color settings scene by scene, rather than applying the same settings to an entire movie. When watching Dolby Vision content on Netflix or Disney+, the G4 delivers superior HDR performance with better highlight detail and more accurate colors.

The Samsung S85F supports HDR10+ instead of Dolby Vision, which also uses dynamic metadata but isn't as widely supported by streaming services. While HDR10+ is technically capable, the lack of Dolby Vision support means you'll miss out on the optimal viewing experience for much of Netflix's premium content and most theatrical releases on streaming platforms.

In terms of HDR brightness, the G4's advantage becomes clear. Bright HDR highlights, like sunlight reflecting off water or explosions in action movies, appear more impactful on the G4. However, the S85F's QD-OLED technology provides more vibrant colors in HDR content, creating a different but equally impressive viewing experience.

Smart Platform Comparison

The LG G4 runs webOS 24, which I find to be one of the most intuitive smart TV interfaces available. The Magic Remote with point-and-click functionality makes navigation natural, and the interface feels responsive. LG's app ecosystem is robust, with regular updates and good support for streaming services.

Samsung's Tizen OS on the S85F offers a different approach with deeper integration into Samsung's ecosystem. If you have Samsung phones, tablets, or smart home devices, the connectivity and shared features work seamlessly. The SmartThings hub functionality is particularly useful, allowing the TV to control compatible smart home devices without additional hardware.

Both platforms support voice control, but Samsung's implementation feels more comprehensive, with better integration of Bixby and support for multiple voice assistants.

Audio Quality Assessment

Audio represents a clear advantage for the LG G4. Its 60W 4.2-channel system with AI Sound Pro delivers room-filling sound that adapts to your space. The Dolby Atmos support creates a more immersive audio experience, particularly noticeable when watching movies with complex soundscapes.

The Samsung S85F features a more modest 20W 2.0-channel system. While the Adaptive Sound Pro technology works well for dialogue clarity and basic content, it lacks the power and sophistication of the G4's audio system. For serious home theater use, you'll likely want to pair the S85F with a separate sound system.

Home Theater Considerations

For dedicated home theater setups, both TVs have merit, but the LG G4 edges ahead for several reasons. The combination of higher peak brightness, Dolby Vision support, and superior audio makes it better suited for replicating the cinematic experience. The anti-glare coating also performs better if your theater room has any ambient light.
