High Dynamic Range (HDR) /rendering/ is well established in graphics applications to produce images with high precision per color component (enabling high contrast). However, this content is usually "tone-mapped" to lower dynamic range to be displayed on current monitors, sacrificing image quality.
Recent advances in display technology offer the prospect of HDR /display/, preserving image quality through the pipeline from rendering to scanout to user vision.
In this talk, I will give an overview of the building blocks of HDR display and outline the necessary pieces for a Linux graphics driver.
