What is HDR?
HDR is an abbreviation for High Dynamic Range, a display technology that can express a wider range of brightness (dynamic range) than conventional SDR (Standard Dynamic Range).
HDR is a technology that aims to express a natural image as seen by the human eye by widening the range of brightness of the image compared to normal images (SDR).
As shown in the figure below, in general SDR images, shadows are crushed and sunlight is blown out, but in HDR images, it is possible to depict more natural and realistic images without sacrificing the gradation of either bright or dark areas.
HDR is attracting attention as the next generation of high-quality image technology, and video distribution services such as Netflix and UHD Blu-ray have already started distributing content created in HDR.
However, in order to support HDR, the graphics output on the PC side must support DisplayPort 1.4 or higher, and the input side must support HDMI 2.0b or HDMI 2.1.
Please note that if both the signal output and input sides are not compatible, you may not be able to set the resolution you want (resulting in a lower refresh rate, etc.). This restriction also applies when converting a PC's DisplayPort output to HDMI and connecting an HDMI monitor. The source (PC output), target (monitor input), cable, and conversion adapter must all support the above. What did you think? Today we explained HDR. Please use this as a reference for your future considerations.
