When it comes to upgrading your home entertainment setup, few decisions are as impactful as choosing the right television. Today, we're comparing two distinct contenders in the premium 4K TV market: the Samsung 65" S90F OLED 4K Vision AI Smart TV 2025 and the Hisense 65" H9G Quantum Series 4K UHD Smart Android TV. These TVs not only represent different brands but fundamentally different display technologies—each with its own strengths and compromises.
Before diving into our detailed comparison, it's worth understanding what makes these two TVs so different from each other, despite both being marketed as premium 4K options.
The Samsung S90F OLED, released in early 2025, represents Samsung's mid-tier offering in their current OLED lineup. It sits below their flagship S95F model but incorporates many of the same advanced technologies. The television utilizes QD-OLED technology (Quantum Dot OLED), which combines the perfect blacks of OLED panels with the enhanced color and brightness capabilities of quantum dots.
In contrast, the Hisense H9G Quantum Series was released back in 2020 and uses what Hisense calls ULED technology—essentially an enhanced LED-LCD display that incorporates quantum dots and advanced local dimming. At the time of its release, the H9G was considered somewhat revolutionary for delivering near-premium picture quality at a more accessible price point.
The five-year technology gap between these models is significant in the rapidly evolving TV market. During this period, we've seen substantial improvements in processing power, smart features, and panel technology. The question is: does the older Hisense still hold up against Samsung's newer offering, or is the price gap justified by genuine performance differences?
The most critical difference between these televisions lies in how they create an image.
The Samsung S90F uses OLED technology, where each pixel generates its own light and can be turned completely off independently. This self-emissive approach enables perfect blacks (since pixels can be completely turned off) and infinite contrast ratios. Samsung enhances their OLED panels with quantum dot technology, which improves color volume and brightness compared to conventional OLED displays.
"OLED provides a viewing experience that's simply unmatched for movie nights," explains video calibration expert Vincent Teoh. "When a pixel can turn completely off, you get absolute blacks that create a sense of depth conventional LED TVs simply cannot match."
The Hisense H9G, meanwhile, uses a full-array LED backlight system with local dimming technology. This means the screen is illuminated from behind by LED lights divided into 180 separate zones that can dim or brighten independently. While this allows for good contrast control, it can't match the pixel-level precision of OLED. When a bright object appears against a dark background, you might notice some "blooming"—a halo effect where light bleeds beyond the bright object's boundaries.
Both TVs employ quantum dot technology for enhanced color reproduction, but they implement it differently. Samsung integrates quantum dots directly into their OLED structure, while Hisense uses them as an enhancement layer in their LED-LCD design.
What does this technology difference mean when you're actually watching content?
In a darkened home theater environment, the Samsung S90F OLED delivers a notably more immersive experience with its perfect blacks and precise highlight control. When watching movies with dark scenes—think space sequences in "Interstellar" or shadowy horror films—the difference is immediately apparent. The OLED can display a bright star against a perfectly black space background with no light bleeding around it.
The Hisense H9G still performs admirably in dark scenes thanks to its local dimming technology, but careful observers will notice that blacks appear more as very dark gray in challenging scenes, and bright objects on dark backgrounds show subtle blooming effects.
Where the Hisense fights back is in very bright rooms. With its higher peak brightness capabilities (reaching up to 1000 nits), it can punch through ambient light better than earlier generation OLEDs could. That said, Samsung's 2025 OLED technology has significantly improved brightness capabilities compared to OLEDs from 2020, narrowing this historical advantage.
Contrast ratio—the difference between the brightest whites and darkest blacks a display can produce—is arguably the most important aspect of picture quality.
The Samsung S90F delivers what's technically an infinite contrast ratio because its pixels can produce zero light when displaying black. This creates a sense of depth and realism that's particularly noticeable when watching cinematic content in a darkened room.
"The first thing I noticed when setting up the S90F in my testing environment was how the image seemed to have a three-dimensional quality to it," notes home theater enthusiast Maria Chen. "This is what happens when you combine perfect blacks with Samsung's latest processing—objects on screen have a tangible presence."
The Hisense H9G achieves impressive contrast for an LED-LCD television thanks to its 180 local dimming zones. In most everyday content, it delivers satisfying black levels. However, in challenging scenes like a starfield or end credits on a black background, the limitations become apparent. The local dimming algorithm must decide whether to dim or brighten zones containing both light and dark elements, resulting in either slightly elevated blacks or slightly dimmed bright areas.
High Dynamic Range (HDR) content is designed to display a wider range of brightness levels and colors than standard content, creating more realistic and impactful images.
The Hisense H9G Quantum Series was renowned for its brightness capabilities when released in 2020, easily hitting peaks of 1000 nits in HDR highlights. This made it exceptional for HDR content, particularly in brighter viewing environments.
The Samsung S90F OLED represents significant progress in addressing OLED's historical brightness limitations. While early OLEDs struggled to exceed 700-800 nits peak brightness, Samsung's 2025 QD-OLED technology pushes much closer to the 1000-nit threshold while maintaining perfect black levels. The result is HDR content that maintains spectacular contrast while delivering impactful highlights.
What's particularly impressive about Samsung's implementation is how it maintains color volume at higher brightness levels. Traditional LCD-based displays often lose color saturation as brightness increases, but Samsung's quantum dot enhancement helps maintain vibrant colors even in the brightest highlights.
Both televisions leverage quantum dot technology to achieve excellent color reproduction, but there are notable differences in their implementation and results.
The Samsung S90F benefits from the integration of quantum dots with OLED technology, allowing it to reproduce nearly 100% of the DCI-P3 color space used in modern cinema. Colors appear rich and vibrant without looking artificially enhanced, and the television maintains excellent color accuracy even without professional calibration.
The Hisense H9G also delivers impressive color performance with its quantum dot enhancement layer, though it tends to prioritize vibrancy over absolute accuracy in its default settings. With proper calibration, it can achieve very good color accuracy, though it still trails the Samsung in terms of color consistency across different brightness levels.
"What impressed me most about the S90F's color reproduction was the subtlety," explains color grading professional Alex Morgan. "It's not just about reproducing vibrant reds and blues—it's about handling the delicate shifts in skin tones and natural environments that make images feel real rather than artificial."
The five-year gap between these models is perhaps most evident in their processing capabilities.
The Samsung S90F OLED features Samsung's latest NQ4 AI Gen3 processor, which leverages neural network technology to enhance upscaling, noise reduction, and motion handling. When watching non-4K content (which is still the majority of available material), the processor analyzes the image and intelligently adds detail without introducing artifacts.
Samsung's AI-based processing is particularly effective at enhancing the perceived sharpness of images without creating the artificial "over-sharpened" look that plagued earlier enhancement algorithms. The processor also adapts its approach based on content type—treating sports, animation, and film each differently to optimize the viewing experience.
The Hisense H9G, using 2020 processing technology, still delivers good upscaling and enhancement but lacks the contextual awareness and refinement of Samsung's latest chips. Standard definition content appears noticeably less refined when upscaled, and the system is less adept at preserving film grain while removing actual noise.
How a TV handles motion can dramatically impact the viewing experience, especially for sports and action films.
The Samsung S90F benefits from a native 144Hz panel and advanced motion processing algorithms. The higher refresh rate allows for smoother handling of 24fps movie content (which divides evenly into 144), and Samsung's Motion Xcelerator technology effectively reduces motion blur without introducing the artificial "soap opera effect" that makes films look like video.
"For sports fans, the S90F's motion handling is a particular highlight," notes sports broadcaster James Wilson. "Fast-moving objects maintain their clarity without the smearing effect you often see on lesser displays. For football or hockey where tracking fast movement is crucial, this makes a substantial difference."
The Hisense H9G features a native 120Hz panel and proprietary Motion Rate 480 technology. While it performs admirably for its era, side-by-side testing reveals more motion artifacts, especially in complex scenes with multiple moving objects. Its motion interpolation features work well for sports but can make film content look somewhat unnatural when enabled.
The user interface and smart features of a TV have become increasingly important as streaming continues to dominate content consumption.
The Samsung S90F runs on Samsung's latest Tizen OS platform, which has evolved significantly since 2020. The 2025 version features a more intuitive layout, faster response times, and Samsung's Vision AI technology that can analyze on-screen content and optimize picture settings accordingly. The enhanced Bixby voice assistant can understand more natural language commands and control compatible smart home devices.
One standout feature is Samsung's AI Mode, which uses ambient light sensors and content recognition to automatically adjust picture and sound settings based on your viewing environment and what you're watching. In practice, this means the TV might brighten slightly when it detects increased room lighting, or enhance dialogue clarity during conversation-heavy scenes.
The Hisense H9G runs on Android TV (not the newer Google TV platform that succeeded it), which was excellent for its time but now feels somewhat dated in comparison. App loading times are noticeably longer, and the interface lacks the contextual awareness of newer systems. That said, it still provides access to virtually all major streaming platforms and includes built-in Chromecast functionality.
For gamers, especially those with current-generation consoles like the PlayStation 5 or Xbox Series X, TV specifications can significantly impact gaming experience.
The Samsung S90F OLED is fully equipped for next-generation gaming with four HDMI 2.1 ports capable of handling 4K resolution at up to 144Hz refresh rates. It supports Variable Refresh Rate (VRR) technology, which eliminates screen tearing by synchronizing the TV's refresh rate with the console's output. Auto Low Latency Mode (ALLM) automatically detects when you're gaming and switches to the lowest-latency mode.
Input lag—the delay between pressing a button on your controller and seeing the action on screen—is remarkably low at approximately 10ms in game mode, making it suitable even for competitive gaming where split-second reactions matter.
The Hisense H9G, being a 2020 model, lacks full HDMI 2.1 implementation and is limited to 4K at 60Hz. It has a basic game mode that reduces input lag to around 15-20ms—acceptable for casual gaming but not ideal for competitive play. It also lacks VRR support, which means you might experience screen tearing during graphically intensive gameplay when the frame rate fluctuates.
"The gaming experience on the S90F is genuinely impressive," shares gaming developer Sarah Johnson. "The OLED's instant pixel response time eliminates motion blur in fast-paced games, and the HDMI 2.1 features ensure you're getting the most out of current-gen consoles. The difference is particularly noticeable in games that support 120Hz output."
Let's address the elephant in the room: the significant price difference between these models.
The Samsung S90F OLED typically retails for around $2,500 for the 65-inch model, positioning it as a premium but not ultra-premium option in Samsung's 2025 lineup. It represents what many would consider the sweet spot in terms of picture quality and features without stepping up to the flagship S95F model.
The Hisense H9G Quantum Series, meanwhile, can often be found for approximately $1,250 for the same size—half the price of the Samsung. This pricing reflects both its older technology and Hisense's positioning as a value-oriented brand.
Is the Samsung worth twice the price? The answer depends entirely on your priorities and viewing habits.
If you're a cinephile who primarily watches movies in a darkened room, the OLED's perfect blacks and infinite contrast will provide a noticeably superior experience that may justify the premium. Similarly, serious gamers will benefit from the Samsung's advanced gaming features and lower input lag.
If you mainly watch daytime television in a bright living room, the Hisense's high brightness capabilities might actually deliver a more satisfying experience at half the price. Casual viewers who aren't particularly concerned with the finest details of picture quality might find the Hisense offers tremendous value.
After thoroughly comparing these two televisions, the decision comes down to your specific needs, viewing environment, and budget.
