We are hiring!
To try to better understand how long a TV should last, we're running 100 TVs through an accelerated longevity test for the next two years. We've just posted our 1-year video update with our latest findings on temporary image retention, burn-in, and more!

Tests

PQ EOTF Tracking

  • Moved the PQ EOTF Tracking graph from the HDR Brightness box to its own dedicated box.
  • Our PQ EOTF measurements are now a website graph, meaning you can compare across TVs.
  • We now measure the PQ EOTF Tracking with three different HDR10 metadata mastering levels:
    • 600 nits (600 cd/m² MDL and 600 cd/m² MaxCLL)
    • 1000 nits (1000 cd/m² MDL and 1000 cd/m² MaxCLL)
    • 4000 nits (4000 cd/m² MDL and 4000 cd/m² MaxCLL)
  • We now score the PQ EOTF Tracking.
    • Based on how closely the TV's luminance output matches the signal input for the shadows and midtones (0% - 58% stimulus / 0 - 203 nits)

Color Volume

  • We no longer use the normalized color volume for our graphs, results, or scoring.
  • The graphs and comparisons now use fixed, unnormalized targets.
    • P3 1,000 cd/m²
    • Rec 2020 10,000 cd/m²
  • The score is now based solely on the "10,000 cd/m² Rec 2020 Coverage ITP" result.
  • The P3 unnormalized result and graph now target 1,000 nits rather than 10,000 nits.
  • Added the color luminance comparisons.
  • Solved an error with one of our tools.
  • Now done with the white point calibrated at 6500k.

Color Gamut

  • Solved an error with one of our tools.
  • Now done with the white point calibrated at 6500k.
