Shoppers looking to make a serious home theater upgrade may want to act fast: the 98-inch TCL QM8K mini LED 4K TV has dropped by 25% in a limited-time Amazon deal, bringing it to a record-low price just under $3,000. For anyone who’s been waiting for a truly gigantic screen without jumping to ultra-premium pricing, this discount puts one of TCL’s most talked-about big-screen TVs into much more attainable territory.
A major reason the TCL QM8K stands out is its brightness performance. In independent testing, the TV was measured peaking at an eye-catching 4,112 nits in small highlights, sustaining around 2,557 nits, and still delivering over 600 nits on a full-screen (100% window) brightness test. In real-world viewing, that kind of output helps HDR content look punchy and dynamic, making bright highlights pop while holding up well even in rooms with lots of ambient light.
The QM8K uses a mini LED backlight with roughly 3,760 local dimming zones, which is a big deal for contrast. With so many zones, the TV can better control light and dark areas on screen at the same time, improving black levels and helping fine details stand out in challenging scenes. The result is a rich, vivid image that feels more “premium” than many standard LED TVs, especially for movies and high-quality streaming content.
Color performance is a bit more nuanced. HDR color volume is said to be competitive with top-tier options, helping bright, colorful scenes look intense and lifelike. Standard dynamic range (SDR) color, however, may be less impressive—particularly in greens and reds. Interestingly, accuracy flips depending on the mode: SDR is generally more accurate, while HDR color accuracy is more mixed and could be a sticking point for viewers who are sensitive to color precision.
For gaming, the TCL QM8K checks a lot of key boxes. It offers a 144 Hz refresh rate along with variable refresh rate (VRR) support, which helps reduce screen tearing and keep gameplay smoother on compatible consoles and PCs. There’s also an option for high-frame-rate 1080p gaming up to 288 Hz, a feature that will appeal to competitive players who prioritize responsiveness over resolution.
No TV is perfect, and the QM8K has a couple of practical drawbacks to consider. Reflection handling is described as decent for a glossy screen, but not class-leading. More importantly, viewing angles are a weak point, which means the picture can degrade when watched from the side. If you frequently host large group viewing sessions spread across a wide seating area, that limitation may matter.
Even with those compromises, the current deal makes the 98-inch TCL QM8K a compelling option for buyers who want an enormous 4K mini LED TV with standout brightness, strong contrast, and modern gaming features. If your goal is a dramatic screen-size upgrade for movies, sports, and gaming—and you typically watch straight-on—this price drop makes it one of the more tempting big-screen values available right now.
