VESA's new initiative defines three different levels of support for VESA,HDRTo help consumers understand what they are getting for their money
It is already clear to almost everyone that HDR Is the future technology in the medium of display, with the ability to display higher contrast, wide and accurate color gamut and other elements that will make everything we have so far expected to pale and bleak - but nevertheless, the lack of clear and agreed definition of the nature of the display HDR ("Real Dynamic Range") "real" has impaired the domain's ability to develop properly, with the manufacturers themselves finding it difficult to explain and characterized by disagreement, without mentioning to consumers that, in a large part, they can't quite understand what all the fuss is about.
Those who volunteer to do one thing for good in the field are the VESA (Video Electronics Standards Association), which is responsible for developing various standards for the video and audio field over the past thirty years - with the most famous and common signal being the advanced DisplayPort connection Video Digital.
In VESA Decide to set three different levels, With measurable numeric data as clear as possible, to support everything that distinguishes between display HDR For simple SDR displays - DisplayHDR 400, DisplayHDR 600, and DisplayHDR 1000, with maximum brightness requirements both instantaneously and over time, maximum brightness levels when displaying black color (which together help define the contrast obtained from the display, in effect), the percentage of coverage The color gamut of the sRGB standard and even the standard DCI-P3 standard in the device's high ranks, maximum 133 millisecond response time from minimum brightness to maximum backlight brightness, as well as compulsory use of 10 bit for video signal sampling and 8 bit Dithering algorithms when displaying the image on the background.
The DisplayHDR standard will be free to use and self-authenticated by the company's manufacturers, with enforcement of compliance by the consumers themselves, with free tools to test the display at the various levels of standards to be distributed during the first quarter of 2018. This method will make the device free for use, technical, and probably also common enough to finally bring uniformity and comparative potential to the field.
Additional DisplayHDR levels will be added later depending on the demand and development of the field, and in the meantime there are already סמסונג Who decides to give a positive boost to the venture and announce that its crazy ultra-wide, ultra-wide CHG90 screen and xNUMX-inch diagonal size officially supports the DisplayHDR 49 standard - although there is currently no easy way to verify the data. It might not eliminate the standardsHDR The others who are already roaming the market, but it can certainly make life easier for ordinary users.
