How do we calculate the rating score?

We use ten main criteria for calculating our rating score. Each of the ten is weighted equally in the final score. Each criterion is divided into sub-criteria. However, these are not weighted equally. The percentage given in brackets next to each sub-criterion indicates how much importance we place on a given factor. Color Volume is an exception because the percentage values in this case correspond approximately to the code words distribution for the 10-bit HDR10 signal. The percentage values are given independently for each of the ten main criteria, meaning that, for example, 100% of our Sound rating is 1 from the total score of 10. We may revise how we calculate the rating, in whole or in part, from time to time. The latest version will be posted here (and any existing rating score(s) affected by such revision will be updated).

1. Color Volume
More than 95% DCI-P3 coverage independently for any of the following:
– shadows (less than 1cd/m2) (20%)
– mid-tones (1cd/m2 – 400cd/m2) (45%)
– diffuse white (400cd/m2 – 1000cd/m2) (10%)
– specular highlights (more than 1000cd/m2) (25%)

2. Dynamic Range
The peak brightness on a 5% window when the TV is calibrated to D65 white point is:
– less than 600cd/m2 (10%)
– 600cd/m2 – 800cd/m2 (20%)
– 800cd/m2 – 1,000cd/m2 (30%)
– 1,000cd/m2 – 1,500cd/m2 (40%)
– more than 1,500cd/m2 (50%)
The black level on a checkerboard pattern is:
– less than 0.1cd/m2 (20%)
– less than 0.05cd/m2 (30%)
– less than 0.01cd/m2 (40%)
– less than 0.001cd/m2 (50%)

3. HDR format support
– HDR10 (70%)
– Dolby Vision (20%)
– HLG (Hybrid Log Gamma) (10%)

4. Bit depth
– 10-bit panel (90%)
– upconverting 8-bit or 10-bit source to higher bit rate (e.g. 14-bit) for processing (10%)

5. Motion
– pixel response time of 1 ms or less (30%)
– pixel response time of 16.7 ms or less (20%)
– input lag of 30 ms or less (30%)
– 120Hz native refresh rate (30%)
– black frame insertion (or equivalent technique) (10%)

6. Lower resolution content
– depends on the quality of upscaling (10% to 100%)

7. Viewing Angle
– retaining at least half of its 0 degree’ peak brightness until at least 45 degree angle (35%)
– preventing the black level from raising at least until 45 degree angle (35%)
– no perceivable color shift until at least 45 degree angle (30%)

8. Sound
– 40 Watts of amplification or more (40%)
– between 20 Watts and 40 Watts of amplification (30%)
– front-firing speakers (30%)
– bass-reflex speakers (20%)
– subwoofer (20%)
– Dolby Atmos decoder (10%)

9. Design & Connections

– at least 4 HDMI inputs (10%)
– at least one USB 3.0 input (10%)
– HDMI port that supports Audio Return Channel (10%)
– HDMI port(s) that support HDCP 2.2 (10%)
– support for full chroma resolution 4:4:4 (10%)
– build quality (10%)
