TCL 55-inch QM6K QD-Mini LED QLED 4K Google TV

Model details

Additional useful information

Use this source-reviewed TCL 55QM6K guide to set up Google TV, recover from common picture or audio problems, and evaluate cables, remotes, stands, antennas and mounts without assuming cross-size compatibility.

The first U.S. QM6K size, with a manual-backed mount record and a web-spec anomaly. TCL's online fifty-five-inch QM6K dimension and weight block repeats sixty-five-inch values, so this record deliberately uses the manual's mounting pattern and withholds the suspect weight. Display evidence: QD-Mini LED backlighting, QLED color and HVA panel technology; native 144 Hz and VRR up to 144 Hz, with 4K 144 Hz supported through the signal chain. HDR10, HDR10+, HLG, Dolby Vision, Dolby Vision Gaming and Dolby Vision IQ. Connection evidence: four HDMI inputs including one eARC, Ethernet, one USB 2.0, one USB 3.0 and optical digital audio. For first use, install the exact stand hardware or verified bracket, connect power and sources, and complete the on-screen language, network and Google TV choices. U.S. smart features need internet service and a Google account; antenna or cable users should select the U.S. broadcast source and run a channel scan. If settings or apps remain unstable after a normal restart and software update, use Settings > System > About > Factory reset and follow the prompts. A factory reset removes local accounts, apps, networks and preferences, so record picture, audio and accessibility choices before using it. For no picture, confirm power, select the numbered input actually carrying the source, reseat both HDMI ends and test a known-good source at a supported mode. For external-audio silence, follow this connection boundary: The U.S. user manual assigns eARC to HDMI 4. Then select the intended audio output and confirm HDMI control/CEC where the guide requires it. Power-cycle the television and connected device before escalating to reset. 55QM6K is documented at 300 x 300 mm, weight withheld because TCL's 55-inch web block repeats 65-inch dimensions, using four M6 x 16 mm wall screws. These values come from 50-85QM6K U.S. user manual; bracket load rating, wall construction, spacers, effective engagement, access and ventilation still control the installation. Remote replacement remains evidence-driven: included backlit Google TV Voice Remote with two AAA batteries; no replacement part number is asserted. Stand parts must name the full 55QM6K, because feet, pedestals and screws are not transferable merely because another set shares the QM6K name. Broadcast setup is also region-scoped: ATSC, NTSC and Clear QAM for the U.S. model.

• Connections: four HDMI inputs including one eARC, Ethernet, one USB 2.0, one USB 3.0 and optical digital audio
• HDMI rate boundary: TCL documents 4K 144 Hz capability but does not publish a public port-by-port maximum-rate matrix, so this record does not call all four jacks 4K144 inputs
• ARC/eARC boundary: The U.S. user manual assigns eARC to HDMI 4
• Mounting: 300 x 300 mm, four M6 x 16 mm wall screws; weight withheld because TCL's 55-inch web block repeats 65-inch dimensions
• Remote boundary: included backlit Google TV Voice Remote with two AAA batteries; no replacement part number is asserted
• Broadcast boundary: ATSC, NTSC and Clear QAM for the U.S. model
• Stand boundary: exact 55QM6K stand kit and manual only
