The TCL QM8K is an incredibly bright TV. All HDR content stands out incredibly well, from the smallest specular highlights to large bright scenes; it just pops. It can’t sustain specular highlights for very long, but this really isn’t an issue with the vast majority of content, as specular highlights aren’t normally visible for more than a few seconds anyway.
Here are measurements with Dynamic Tone Mapping (DTM) set to each of its three settings, all in the ‘Movie’ HDR Picture Mode:
Results with DTM set to Detail Priority:
- Hallway Lights: 889 cd/m²
- Yellow Skyscraper: 610 cd/m²
- Landscape Pool: 496 cd/m²
Results with DTM set to Balance:
- Hallway Lights: 967 cd/m²
- Yellow Skyscraper: 597 cd/m²
- Landscape Pool: 510 cd/m²
Results with DTM set to Brightness Priority:
- Hallway Lights: 972 cd/m²
- Yellow Skyscraper: 607 cd/m²
- Landscape Pool: 556 cd/m²
