In terms of technical standards, the open HDR-10 in the television arena, the patented Dolby Vision and the VESA (Video Electronics Standards Association) are now rolling out the first new HDR technology standard, DisplayHDR 1.0, for PC monitors.
The DisplayHDR standard is developed to bring together more than 20 chips, display panels, monitors, PCs and system vendors in the industry including Intel, AMD, NVIDIA, Microsoft, Analogix, JDI, LG Display, Samsung, AU Optronics, Innolux, Asus, Dell, HP, Lenovo, Morningstar, Realtek, MegaChips, Portrait Displays and more.
The DisplayHDR 1.0 standard defines three different levels for LCD monitors that account for more than 99% of the market, with varying specifications for display brightness, color gamut, color depth, etc., but all must have a true 8-bit color display panel Market share of about 15%):
DisplayHDR 400 is the lowest end, supporting global dimming with peak brightness not less than 400nit and global continuous brightness of not less than 320nit. Coverage of ITU-R BT.709 gamut (basic and sRGB gamut) is not less than 95% And supports HDR-10.
The DisplayHDR 600 requires 10-bit processing capability for high-end displays and notebooks with 600nit peak brightness, 350nit brightness, black-and-white brightness response time of less than 8 frames and 99% color gamut coverage. ITU-R BT.709, 90% DCI- P3 65.
DisplayHDR 1000 only professional display to be competent, the peak brightness 1000nit, continuous brightness 600nit, while the color gamma has improved significantly.
In the future if we want to buy HDR monitor, you can judge based on the above three certification levels.
