HDR changes include HLG and ICC-profile handling.

KWin adds support for HDR content using the HLG transfer function. KDE also reports improved HDR rendering with ICC profiles and enables triple buffering by default for NVIDIA GPUs. These are software changes, rather than new capabilities added to a monitor’s panel.

The new kscreenctl command-line tool supports display management and automation. Display Configuration allows pixel-by-pixel positioning with arrow keys, while the screen-sharing portal can create virtual displays at a chosen resolution instead of only 1920 × 1080.
