Tone mapping shapes their placement within a chosen display range. Display encoding then produces the signal expected by the output path. ACES explicitly separates rendering from display encoding; its output transform also considers target gamut and luminance. [1]\n\nAn HDR render target does not by itself enable HDR presentation. The operating-system path, swap-chain configuration, display capabilities, and output colour interpretation must agree.
