408nits11Measurementrtings.com/tv/tests/picture-quality/hdr-peak-brightnessRead 7 October 2026Published HDR test method: real scenes supplied by Murideo 7G, measured using Konica Minolta LS-100. Hallway metric is the greater peak luminance from the two overhead lights. Test Bench 1.7 introduced the real-scene measurements and HDR white-point calibration. Not a whole-scene average or SDR result.12Reviewrtings.com/tv/reviews/tcl/qm6k/settingsRead 7 October 202675QM6K calibration settings published April 2, 2025. HDR Movie, brightness 100, black 50, gamma 2.2, Local Contrast Low, Peak Luminance High-Dynamic and Warm 5. Base method DTM Off differs from explicitly named Brightness Priority alternate result. Android TV 12 build STT2.230203.001 disclosed. About 22GB accessible storage is not used as physical flash capacity.13Measurementrtings.com/tv/reviews/tcl/qm6kRead 7 October 2026Public HDR Brightness alternate measurements: Hallway Lights 408 cd/m², Movie HDR Picture Mode, Dynamic Tone Mapping Brightness Priority, tested standard US 75QM6K. This is the real-scene overhead-light highlight, not average screen brightness, a window value or the default DTM-Off row. Other scenes in that setting were Yellow Skyscraper 268 and Landscape Pool 232. Review settings describe HDR brightness 100, black 50, gamma 2.2, Local Contrast Low, Peak Luminance High-Dynamic, Warm 5. DTM differs explicitly for this alternate run. Method uses a Murideo 7G real-scene source and Konica Minolta LS-100 luminance meter. Test firmware/OS disclosed at calibration: Android TV 12, STT2.230203.001. Exact firmware for the alternate run and room luminance are not stated.
