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 It is the technology of the future in the field of display media, with the ability to display higher contrast, wide and precise color assemblies and other elements that will make everything we have been used to watching so far pale and gloomy in comparison - yet lacking a clear and agreed definition of the essence of display HDR (Real High Dynamic Range) has "damaged" the field's ability to develop properly, with the manufacturers themselves having a hard time explaining and being characterized by disagreement between them, without mentioning consumers who in most cases fail to really understand what all the fuss is about.
The one who volunteers to make order once and for all in the field is the VESA (RT Electronics Video Standards Association), which is responsible for developing various standards in the field of video and audio in the last thirty years - the most famous and common of which is probably the advanced DisplayPort connection for signal transmission 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 the simple SDR displays - DisplayHDR 400, DisplayHDR 600 and DisplayHDR 1000, with maximum brightness requirements both momentarily and over time, maximum brightness levels when displaying black color (which together help define the contrast obtained from the display, in effect), the coverage percentage of The range of colors in the sRGB standard and even in the professional DCI-P3 standard in the higher grades of the standard, a maximum response time of 133 milliseconds in transition from minimum brightness to maximum brightness of the backlight as well as binding 10-bit for video signal sampling and 8-bit together with Dithering algorithms when displaying the image on the screen.
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 Which decides to give a positive development to the venture and announce that its insane CHG90 screen, which has ultra-wide dimensions and a 49-inch diagonal size, officially supports the DisplayHDR 600 standard - although there is currently no easy way to verify the data. This may not eliminate the standardsHDR The others who are already roaming the market, but it can certainly make life easier for ordinary users.
