-- Kuycon P20 on DP-2: 4500x3000 @ 60Hz, 1.5x fractional scale.
-- 4500/1.5 = 3000 and 3000/1.5 = 2000, both integers, so this is a "clean"
-- fractional scale and Hyprland will not complain.
--
-- On HDR --------------------------------------------------------------------
-- GNOME runs this panel in bt2100/HDR. Hyprland CAN do that (cm = "hdr"), but
-- on 0.56.x it currently breaks screencopy: grim screenshots come back empty,
-- and OBS/Sunshine capture and hyprlock's blurred background go with them.
-- Root cause is still open upstream. Since screen capture matters more here
-- than an HDR desktop, the desktop runs SDR at 10-bit and HDR is handed to
-- fullscreen games only, via render.cm_auto_hdr in looks.lua.
--
-- To try full-time HDR anyway, set cm = "hdr" below (or override it in
-- overrides.lua) and read the notes in that file first.

-- Only mode, scale, and transform are read. Colour management and bit depth
-- stay here, because those are the settings with a documented reason attached
-- (see the header) rather than preferences, and a settings page has no way to
-- explain the screencopy tradeoff at the moment you would be changing it.
