TCL 75QM5K 75"

Manufacturer: TCL

The TCL 75QM5K is a 75″ class television built around a Mini-LED backlit QLED LCD panel, combining a large screen footprint with a broad set of display and smart platform features. Running a built-in smart TV system, it supports Google Assistant, Amazon Alexa, Chromecast, and AirPlay, giving users several options for voice control and content streaming. The set resolves content at 4K (3840 x 2160) across its 74.5″ panel, resulting in a pixel density of 59 ppi.

On the display side, the TCL 75QM5K supports HDR10, HDR10+, Dolby Vision, and HLG, while its 144Hz refresh rate is paired with AMD FreeSync adaptive sync for smoother motion handling. Typical brightness is rated at 500 nits, and the panel covers a wide color range with 1,070 million colors at 10-bit depth. Connectivity includes three HDMI 2.1 ports with ARC and eARC support, one USB port, an RJ45 jack, and Wi-Fi 5 along with Bluetooth. Audio-wise, the TV carries stereo speakers with a subwoofer, and supports Dolby Atmos, Dolby Audio, Dolby Digital Plus, and DTS:X.

Pros

Supports all four major HDR formats — HDR10, HDR10+, Dolby Vision, and HLG — covering a wide range of content sources
A 144Hz refresh rate combined with AMD FreeSync adaptive sync reduces motion judder and screen tearing during fast-moving content
Built-in Chromecast and AirPlay allow wireless streaming from both Android and Apple devices without additional hardware
Voice control works with both Google Assistant and Amazon Alexa, offering flexibility depending on the smart home ecosystem in use
The panel's 178° horizontal and vertical viewing angles mean the image remains consistent across a wide seating range
Audio output covers Dolby Atmos, DTS:X, and includes a built-in subwoofer, providing a more complete sound setup without an external speaker

Cons

Only one USB port limits simultaneous connection of storage devices or peripherals
There is no 3.5 mm headset jack, so wired headphone use requires an adapter or alternative audio output
The remote control is not rechargeable, requiring regular battery replacement
Siri and Apple HomeKit are not supported, limiting integration for users within the Apple ecosystem
Wi-Fi tops out at Wi-Fi 5 (802.11ac), with no support for the faster Wi-Fi 6 standard
The warranty period covers only one year

Who is this for?

The TCL 75QM5K is well suited to users who want a large-screen viewing experience in a dedicated home entertainment space, particularly those who regularly consume HDR content, since the panel covers all four major HDR formats including Dolby Vision and HDR10+. The 144Hz refresh rate paired with AMD FreeSync also makes it a practical choice for console or PC gamers who want smoother motion and reduced screen tearing on a big display. Additionally, households with mixed smart home ecosystems will find value in the dual voice assistant support for Google Assistant and Alexa, alongside Chromecast and AirPlay for flexible wireless streaming.

Who is this NOT for?

Users who need extensive peripheral connectivity may find this TV limiting, as it provides only a single USB port with no external memory slot, making it less practical for those who regularly connect multiple storage devices or accessories simultaneously. The absence of a 3.5 mm headset jack makes it a poor fit for anyone who relies on wired headphones for private listening without additional workarounds. Furthermore, users deeply embedded in the Apple ecosystem — particularly those who depend on Siri or Apple HomeKit for home automation — will find the lack of HomeKit support a notable gap in day-to-day integration.
