Remember when buying a TV was as simple as choosing the right screen size? Those days are long gone. Today's premium 4K televisions pack an impressive array of technologies that can make choosing the right one feel like deciphering a tech dictionary. If you're considering a high-end 65" television like the TCL 65" QM6K QD-Mini LED 4K TV ($998) or the Hisense 65" H9G Quantum Series 4K UHD Smart Android TV ($1,358), you're looking at two models that represent different generations of display technology.
The home entertainment landscape has changed dramatically in recent years. Streaming has become the dominant way we consume content, gaming consoles demand more from our displays, and picture quality technologies have advanced at a breathtaking pace. When investing in a premium television, several factors should guide your decision:
Display technology is perhaps the most important consideration. The backlighting method and panel type fundamentally determine what kind of picture quality you can expect. HDR (High Dynamic Range) performance—measured by peak brightness and local dimming capabilities—affects how realistically content is displayed. Color accuracy and gamut have been revolutionized by quantum dot technology, while gaming performance hinges on refresh rates and input lag. Add in the smart platform that determines your daily interaction with the TV, and you've got a complex decision to make.
Let's dive into how these two contenders stack up in 2025.
The TCL QM6K and Hisense H9G represent different technological eras. The Hisense H9G was released in 2020, when quantum dot technology was beginning to reach more affordable price points and local dimming zones were becoming a standard feature in premium TVs. At the time, it represented excellent value and competed with much more expensive models from brands like Samsung and Sony.
The TCL QM6K, on the other hand, is a brand-new 2025 model that incorporates the latest display innovations. In the five years between these releases, several key technologies have matured:
This technological context is crucial for understanding the value proposition of each television in 2025.
The most significant difference between these TVs lies in their backlighting technology. The TCL QM6K uses QD-Mini LED technology, which combines quantum dots with mini-LED backlighting. Let me break this down: traditional LED TVs use relatively large LED lights behind the screen to create brightness. Mini-LEDs, as the name suggests, are much smaller—sometimes just 1/40th the size of standard LEDs. This allows manufacturers to pack thousands more of them behind the screen, creating much more precise control over which areas get bright and which stay dark.
The older Hisense H9G uses standard-sized LEDs with quantum dots for color enhancement. While it was impressive for its time with 180 dimming zones, the TCL's approximately 500 dimming zones represent a substantial upgrade. More zones mean less "blooming"—that halo effect you might notice around bright objects on dark backgrounds.
During an evening of watching dark scenes in shows like "Stranger Things," this difference becomes immediately apparent. The TCL's mini-LED system creates much more precise highlights without lighting up surrounding areas, keeping dark scenes appropriately moody while allowing bright elements to pop.
HDR content lives and dies by a TV's ability to produce both deep blacks and bright highlights simultaneously. The Hisense H9G boasted up to 1000 nits of peak brightness—impressive for 2020—while TCL hasn't published specific nit measurements for the QM6K. However, TCL claims their Super High Energy LED Chip technology delivers 53% increased brightness over previous models while improving energy efficiency by 10%.
In practical terms, both TVs can produce excellent HDR highlights, but the TCL likely has the edge in real-world performance due to:
When watching content with extreme contrast—think of a space scene with bright stars against the black void—the TCL's superior light control becomes evident. The stars shine brightly without creating halos, while the black of space remains truly black rather than dark gray.
Both TVs employ quantum dot technology—microscopic semiconductor particles that, when hit with light, emit very specific colored light based on their size. This technology enables displays to produce more saturated and accurate colors than standard LCD panels.
The TCL QM6K uses a newer generation of quantum dots that likely offers improvements in efficiency and color accuracy. It also benefits from TCL's AiPQ Pro processor, which uses artificial intelligence to optimize color, contrast, and clarity in real-time based on what you're watching.
The Hisense H9G was praised in its time for excellent color performance, delivering a wide color gamut that covered most of the DCI-P3 color space (the standard used for digital cinema). However, five years of quantum dot development likely gives the TCL an edge in color precision and efficiency.
When viewing nature documentaries or movies with rich color palettes, both TVs show excellent performance, but the TCL's colors appear slightly more natural and less exaggerated, particularly in subtle skin tones and landscape gradients.
Gaming has become a major consideration for TV buyers, with next-gen consoles and PC gaming demanding more from displays than ever before. Here, the generational gap between these TVs becomes most apparent.
The TCL QM6K offers a native 144Hz refresh rate—meaning it can display up to 144 frames per second—compared to the Hisense H9G's 120Hz. While this might seem like a minor difference, it represents a 20% increase in potential frame rates.
More significantly, the TCL supports Game Accelerator 288, which enables variable refresh rates up to 288Hz. VRR technology allows the TV to synchronize its refresh rate with the output of your gaming device, eliminating screen tearing and stuttering. The Hisense H9G lacks VRR support entirely—a significant omission for serious gamers.
The TCL also boasts FreeSync Premium Pro certification, ensuring compatibility with AMD graphics cards and Xbox consoles. For competitive gamers playing fast-paced titles like first-person shooters or racing games, these features provide a meaningful advantage in responsiveness and fluidity.
Input lag—the delay between pressing a button on your controller and seeing the action on screen—is crucial for gaming. The TCL QM6K features what they call Zero-Delay Transient Response, optimized to minimize input lag in game mode.
While the Hisense H9G had respectable input lag for 2020 (around 15ms in game mode), the newer TCL likely improves on this significantly. When playing reaction-based games, this difference can mean the difference between victory and defeat.
In practical gaming sessions with titles like "Call of Duty" or "Forza Motorsport," the TCL's superior refresh rate and lower input lag create a noticeably more responsive experience, with smoother motion and more immediate feedback to controller inputs.
The Hisense H9G runs on Android TV, Google's smart TV platform as it existed in 2020. The TCL QM6K uses Google TV—the evolution of Android TV introduced in late 2020 and refined over subsequent years.
The difference is more than just a name change. Google TV maintains the same app ecosystem as Android TV but fundamentally reimagines the interface around content rather than apps. Instead of navigating to Netflix and then browsing what's available, Google TV aggregates content across your services and makes recommendations based on your viewing habits.
Having used both platforms extensively, I find Google TV more intuitive for most users. The home screen prioritizes what you might want to watch rather than which app you want to open—a small but meaningful shift in philosophy that makes daily TV use more pleasant.
Both TVs feature Google Assistant integration, allowing you to control the TV, search for content, and control compatible smart home devices using your voice. The Hisense H9G includes built-in microphones for hands-free control, while the TCL QM6K works with both Google Assistant and Amazon Alexa through its remote.
In practice, voice control on both TVs works well for basic commands like "play Stranger Things on Netflix" or "turn down the volume," though the TCL's newer processor likely offers improved response times and capability.
Perhaps the most surprising aspect of this comparison is the price difference. Despite being five years newer and incorporating more advanced technology, the TCL QM6K retails for approximately $998, while the Hisense H9G is priced at around $1,358 in 2025.
This unusual pricing situation likely reflects several factors:
Regardless of the reasons, the TCL represents significantly better value in 2025. You're getting newer technology (Mini-LED, higher refresh rate, better gaming features) at a lower price point. The $360 difference could be put toward a quality soundbar or streaming subscriptions.
If you're building a dedicated home theater setup, both TVs offer certain advantages, but the TCL pulls ahead in key areas.
The TCL QM6K's superior local dimming performance makes it better suited for controlled lighting environments where its contrast capabilities can truly shine. When watching cinema in a darkened room, the improved blooming control creates a more immersive experience, especially during scenes that mix bright and dark elements.
Both TVs support Dolby Atmos passthrough via HDMI eARC, allowing them to send high-quality audio to compatible sound systems. The TCL features a 2.1 channel Onkyo speaker system built-in, likely offering better native sound than the Hisense's standard speakers—though serious home theater enthusiasts will connect an external audio system regardless.
For those who occasionally use their home theater for gaming, the TCL's superior gaming performance makes it the more versatile choice. When friends come over for movie night followed by some multiplayer gaming, the TCL handles both scenarios with aplomb.
After thoroughly comparing these two televisions across multiple dimensions, the decision seems relatively straightforward for most buyers in 2025.

Choose the Hisense 65" H9G Quantum Series 4K UHD Smart Android TV if:
For the vast majority of consumers in 2025, the TCL QM6K represents the clearly superior choice. It combines newer technology, better performance, and a more refined user experience at a lower price point. Unless you can find the Hisense at a steep discount, the TCL offers better value across virtually every dimension.
The technological improvements made between 2020 and 2025 are substantial enough that even a highly-regarded TV like the Hisense H9G—which was considered an excellent value in its time—can't compete with newer models at similar price points. The TCL QM6K's combination of mini-LED backlighting, superior gaming features, and updated smart platform make it the more future-proof investment for most viewers.
As we continue to consume increasingly diverse content on our TVs—from 4K movies to competitive games to video calls—having a versatile display that handles all these scenarios well becomes more important. The TCL QM6K represents that versatility in a way that the aging Hisense simply cannot match, despite its qualities when it was first released.
In the rapidly evolving world of television technology, five years is practically a lifetime. Your next TV will likely serve you for many years to come—investing in the TCL QM6K's newer technology and performance capabilities will ensure your viewing experience remains satisfying long into the future.
