Resolution, refresh rate, scale, and rotation, applied through
hl.monitor{} and stored per output.
This is the only setting in Panama where a wrong value can leave the
user unable to SEE the screen well enough to undo it: a mode the panel
cannot show, or a scale that makes everything unreadable, is not
recoverable through the UI that caused it. So a change is never applied
irreversibly. It is applied, then reverted automatically after fifteen
seconds unless confirmed, and confirming is what writes it to the
settings store -- letting the countdown run leaves nothing behind.
The contract tests that property specifically: it applies a scale, waits
out the countdown, and asserts the display came back and that nothing
was stored. A regression there is not a broken feature, it is a user
staring at a blank monitor.
Modes are grouped by resolution with refresh rates beside them. The
panel reports 35, many differing only in refresh-rate rounding -- 60.00
and 59.94 -- which as a flat list of buttons is noise rather than
choice; equal rounded pairs collapse, leaving 21.
Only mode, scale, and transform are configurable. Colour management and
bit depth stay in monitors.lua because they carry a documented screencopy
tradeoff that a settings page cannot explain at the moment you would be
changing it.
Also replaces the display policy rows with the schema-bound ones, so the
page no longer restates labels that PreferenceSchema already holds.

-- 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"

-- 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.
