The TCL QM8L and QM9K are two prominent Mini-LED TVs from TCL, each catering to different consumer needs. The QM8L, launched in 2026, utilizes Super Quantum Dot (SQD) technology, resulting in a brighter and more vibrant picture. It boasts features like four HDMI 2.1 ports, making it ideal for gamers with multiple devices. In contrast, the QM9K, released in 2025, is less expensive and offers solid performance but lacks SQD, resulting in slightly less colorful visuals. Both models support Dolby Vision and HDR10+, ensuring high-quality viewing experiences. Performance tests indicate that while the QM9K is brighter during HDR content, the QM8L excels in color volume and has lower input latency, enhancing the gaming experience. Priced at $1,799 for the 65-inch QM8L and $1,299 for the QM9K, consumers must weigh the benefits of advanced technology against budget constraints when making a choice.
