Quick view

The TCL 55Q750G is a 55-inch Mini-LED 4K QLED television delivering advanced picture quality through the integration of Quantum Dot technology and local dimming provided by its Mini-LED backlight system. This model features 4K Ultra HD resolution (3840 x 2160 pixels) enhancing visual clarity and color precision. It uses a VA-type LCD panel known for high contrast ratios, which combined with HDR10 and Dolby Vision support, provides vibrant and dynamic images suitable for diverse lighting environments. The TV is powered by TCL’s proprietary AI ThinQ smart platform with built-in Google TV, enabling voice control and access to a wide range of streaming apps. Connectivity includes multiple HDMI 2.1 ports supporting features like eARC and variable refresh rates, making it suitable for high-refresh-rate gaming and next-gen consoles. Advanced audio solutions with Dolby Atmos decoding are integrated, offering an immersive sound experience.

Technically, the use of Mini-LED dramatically improves backlight precision and reduces blooming effects compared to traditional LED panels, enhancing overall contrast and black levels. The screen supports a refresh rate of 120Hz, making fast-motion content appear smoother. Its smart platform runs on a Quad-Core processor ensuring responsive navigation and multi-tasking capabilities. The television supports Wi-Fi 802.11ac for stable wireless connectivity and includes Bluetooth 5.0 for peripheral device pairing. The chassis design includes a slim bezel and sturdy stand, emphasizing both aesthetic appeal and stability.

The TCL 55Q750G's Mini-LED backlighting offers superior local dimming, providing higher contrast with deeper blacks and brighter highlights. Its Quantum Dot technology boosts color gamut, resulting in richer and more vivid visuals. With HDR10+ and Dolby Vision support, it delivers cinematic picture quality for HDR content. The inclusion of HDMI 2.1 ports with eARC enables high-bandwidth audio transmission and compatibility with the latest gaming consoles. Google TV smart platform ensures effortless access to a vast selection of applications and smooth voice control functionality. Finally, Dolby Atmos support enhances the audio experience by creating immersive surround sound in your living room.

Despite its advanced Mini-LED technology, the TCL 55Q750G may exhibit some blooming around bright objects on dark backgrounds due to the finite number of dimming zones. The VA panel, while providing excellent contrast, has narrower viewing angles compared to IPS panels. The smart TV interface can occasionally experience minor lag during heavy multitasking, reflecting limitations in the processing hardware. Its built-in speakers, although enhanced with Dolby Atmos, may not satisfy audiophiles without an external sound system. The absence of certain high-end gaming features like variable refresh rate over all HDMI ports could limit some users. Additionally, OTA firmware updates sometimes delay the introduction of new features or bug fixes.
