La asociacion VESA [Video Electronic Standards Association ], encargada de crear y establecer las especificaciones estandar para los medios visuales de la industria, recientemente ha liberado las nuevas especificaciones para el tema del HDR, las cuales son mas rigurosas y con ello; prometen, se lograria un mejor soporte de los dispositivos que usen dichas tecnologias de las especificaciones.
De esta manera se llega a la version DisplayHDR 1.1, con nuevas reglas de funciones y con una mejor certeza en cuanto al manejo del color, contraste y nitidez y sea tambien mas consistente en los resultados obtenidos en diferentes marcas de televisores/monitores.
.
The DisplayHDR 1.1 specification includes a number of key performance updates, such as:
* Active dimming – DisplayHDR now mandates active dimming performance levels, a feature that when adopted in displays can reduce power consumption and yield significantly darker black levels
* DisplayID accuracy – ensures that accurate luminance and color gamut data is populated in the DisplayID or legacy Extended Display Identification Data (EDID), which enables the GPU to optimize the video signal for that display to ensure the highest display performance
* Dual corner box test – the black-level test has been updated with larger corner box structures to allow for accurate colorimeter measurement of both black and white levels, resulting in improved dynamic contrast ratio testing
* New color gamut specifications – DisplayHDR now includes a 10 percent color patch test in addition to the 100 percent full screen color test, with both tests now using the display’s maximum luminance and RGB primary color values from the DisplayID/EDID; this revised test method more accurately determines the color gamut that will render on the display when running Windows
* Combined color luminance – DisplayHDR has added a mechanism to validate full color volume at the full logo level luminance
* New Delta-ITP test – added to test that the luminance level on the display is correctly rendered, helping to ensure the faithful reproduction of the original content creator’s intent (luminance, and D65 white balance)
* On-screen display (OSD) mode indication – any DisplayHDR-certified monitor with an on-screen menu function must now clearly indicate which modes support DisplayHDR, making it easier for users to optimize their display settings
* DisplayPort certification specification – any DisplayHDR-certified monitor that has a DisplayPort interface must also undergo DisplayPort certification, ensuring that the display performs optimally with VESA DisplayPort-certified cables and other peripherals
.Espremos con eso, en el tema de microsoft y el soporte a HDR de windows 10 mejore en el futuro a mediano plazo, de igual manera los fabricantes de aparatos monitores/televisores les exijan cumplir completamente con estas nuevas reglas
Tambien aparece la nueva especificacion DisplayHDR 1400 que es 3.5X veces lo que venia siendo DisplayHDR 400 en cuanto al contraste, de tal manera que, por decir algo, si en HDR 400 se tenia 1000:1 en HDR 1400 se tiene 3500:1 la relacion de contraste dinamico. Aunque esta destinado al ramo profesional del video.

.The DisplayHDR™ Test Tool allows users to confirm the display parameters including brightness, color and contrast performance of high dynamic range (HDR) laptop and desktop monitors as per the set forth in VESA’s High-Performance Monitor and Display Compliance Test Specification (DisplayHDR). Created by VESA®, the Video Electronics Standards Association, this new test tool has a simple keyboard interface that enables professional and lab-level users of off-the-shelf calibration colorimeters to test and evaluate HDR displays at the three performance levels (DisplayHDR 400, 600 and 1000) outlined in the DisplayHDR specification.
