Features.

One profile saves which screens are on, plus each screen's rotation, position, HDR, brightness and contrast. Switch from the tray.

Left stays left. Positions are worked out from which screen sits next to which, after every rotation or layout change.

Brightness, contrast, presets, RGB and input over DDC/CI. Each monitor shows only what it actually supports.

HDR on or off per screen, with SDR brightness set across each panel's real range.

Per-screen correction from the graphics card, after the monitor's own settings. Checked on NVIDIA; AMD and Intel untested.

One image cut across every screen using physical size, bezel gaps and height offsets.

Keep the mouse on one screen.

Every setting in one file. Back it up, restore it.

Command line: inspect displays, move screens pixel-exact, apply profiles, script anything.

Test-pattern and phone colour matching across mixed brands. Built, reworked after first use, being retested.

Photograph your desk. Markers on each screen give real heights, gaps and angles. Being retested.

Switch profiles on a hotkey, when a program starts, on a schedule, or when screens are plugged in. Built, not yet run by hand.

Recognised, with brightness through Windows. Being tested.

An app always opens in that spot, on that screen.
