Video Electronics Standards Association (VESA) je objavila prvu nadogradnju svog otvorenog standarda koji definira kvalitetu HDR slike na monitorima. Za razliku od UHD Premium certifikata kod televizora koji je vrlo brzo pao u zaborav, DisplayHDR preciznije definira karakteristike i minimalne uvjete za pojedinu kategoriju, što omogućuje korisniku da i na temelju certifikata može zaključiti kakve performanse da očekuje od pojedinog modela i da ih lakše uspoređuje. Osim strožih zahtjeva, VESA je dodala i novu razinu performansi – DisplayHDR 1400, a koji zahtjeva 3.5 puta veći kontrast od prijašnjeg najvišeg nivoa (DisplayHDR 1000). Prvi monitor koji će krasiti Display HDR 1400 certifikat je Asusov ProArt PA32UCG.
Usporedba različitih DisplayHDR kategorija (izvor: displayhdr.org):
DisplayHDR 1.1 specifikacija donosi niz promjena u ključnim performansama, poput:
- 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
