Abstract:
A display system includes a rendering device configured to couple to a display monitor. The rendering device includes a graphics processing unit (GPU) configured to render display images for a video stream to be displayed at the display monitor. The rendering device further includes a central processing unit (CPU) configured to obtain display parameters for the display monitor, the display parameters including data identifying a native color gamut, a native luminance range of the display monitor, and one or more backlighting characteristics of the display monitor, and to configure the GPU to render a display image of the video stream that is tone mapped to the native color gamut and the native luminance range and based on the one or more backlighting characteristics. The display monitor is configured to provide the display image for display without tone re-mapping the display image.
