540 nits but dolby vision? completely pointless. dolby vision was meant to be around 3000 or more nits, yet its implemented on a tv with 540? nah. just marketing talk
Not true. The requirement is 100 nits minimum, although more nits would mean better image. Which TV is capable of 3000 nits?
According to Dolby Vision white paper:
"The prototype Dolby Vision HDR reference monitor (capable of up to 4,000 nits luminance) is used to make the color and brightness decisions. The basis of the Dolby Vision grading process is to establish the artistic intent in the HDR grade. The artistic team should use the grading system and the monitors to make the best, most engaging imagery they can, taking full advantage of the dynamic range of the display. After the reference grade is done, the Dolby Vision capable color-grading system will analyze and save the metadata that describes the creative decisions made on the display. The content mapping unit (CMU) maps the content with the metadata to a reference display at a standard brightness (100 nits).
The algorithms developed to enable the CMU to generate the 100-nit grade will also be used in the future to enable live Dolby Vision sport productions and, in parallel, automatically generate the 100 nit version required for compatibility with today’s television receivers. After the trim pass has been approved, the colorist exports the images with metadata. The metadata generated to create the 100-nit grade can be used to render the HDR master on displays, which may offer a wide performance range. A 600-nit TV will look great, a 1200-nit TV will look even better—all referencing the same metadata and HDR reference images."
So a 600-nit TV should be able to support Dolby Vision. LG's signature range is capable of 600 nits.
