At TechRadar, we measure the color gamut support of all TVs we review, to help provide you with information on which can show video the closest to the source material. To run these tests, a pattern generator, such as the Murideo 8K SIX-G, and a colorimeter, such as the Portrait Display C6, are used. All our reviewers have equipment that we’re satisfied will produce accurate and comparable results when testing the best TVs.
The ultra-high-definition TV standard defines a color space with a greatly expanded range over the Rec.709 color space used for the regular high-definition TV standard. This color space, BT.2020 (also known as Rec.2020), isn’t used by any current video sources, but it provides a future-proof option for new formats that may be forthcoming.
