Model details

Additional useful information

Use this source-reviewed TCL 55QM7K 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 smallest QM7K, combining CrystGlow HVA imagery with Bang and Olufsen-tuned sound. The entry QM7K size uses CrystGlow HVA, Audio by Bang and Olufsen, and VESA adapters with its documented M6 wall screws, distinguishing it from QM6K hardware. Display evidence: QD-Mini LED backlighting, QLED color and a CrystGlow HVA panel; native 144 Hz and VRR up to 144 Hz with official 4K 144 Hz family support. HDR10, HDR10+, HLG and Dolby Vision formats with an exact-size HDR 2600-nit specification. 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 reviewed U.S. user guide 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. 55QM7K is documented at 300 x 300 mm, 29.3 lb without stand, using four M6 x 20 mm wall screws with the supplied VESA adapters. These values come from TCL product specification and 55-85QM7K U.S. user guide; 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 55QM7K, because feet, pedestals and screws are not transferable merely because another set shares the QM7K name. Broadcast setup is also region-scoped: ATSC, NTSC and Clear QAM for the U.S. model.
