New Tool Plots Gamut Rings In Just 60 Seconds

At Display Week 2023, the ever genial Brian Berkeley introduces Dr. Kenichiro Masaoka of NHK, the ‘father’ of BT2020, who demonstrates a new tool that can measure over 600 patches and plot the gamut rings of a display in just 60 seconds. Dr. Masaoka also shows off software that is able to characterize a video signal using gamut rings in real time. Conventional scopes, like the CIE chromaticity diagram in DaVinci Resolve, are simply unable to show the all-important luminance axis. Berkeley expects manufacturers and reviewers like CNET and rtngs.com to begin using gamut rings to evaluate displays in the near future. To the best of our knowledge, only one tech website, DDay.it, currently characterizes displays using gamut rings.
