What is the HDR function in a projector and what does it do? For many friends who are new to projection, they really don't know much about this function. Usually the HDR function is used for the camera, and using this function can make the photos look better.
So after adding this technology to the projector, will the picture become better? The answer is yes, the HDR function can allow the display of the device to retain more of the light and dark details of the original picture, making the picture closer to what we see with the human eye. Let's take a closer look at the HDR function.
HDR is the abbreviation of High Dynamic Range in English, which means high dynamic lighting rendering in Chinese. So what does HDR mean, we can start with the concept of DR. DR is actually a technical term that mathematically describes the range of brightness levels in a given scene, which, to put it bluntly, refers to the ratio between the brightest and darkest places in an image. The HDR technology is to make the bright areas of the image brighter, and the black areas darker.
The main function of HDR is actually to display more dark details, which requires the projector to have a higher brightness, which can optimize the display of more details. Therefore, after the projection is turned on in HDR mode, when watching some night scenes or pictures in a large exposure environment, the film effect will be better and the experience will be better.

(With HDR)
In summary, we can find that the HDR function of the projector is largely the icing on the cake. It needs the projection itself to have high-brightness support, and high-brightness support can maximize the effect of HDR.
