Get screen

Remember a screen's size, position, scale and DPI in a variable.

Where
+ Add actionWindowGet screen
Get screen set to The foreground window's screen, remembering it as the variable screen with the scope This run; a line under the setting lists the screens right now: 1: 2560 × 1440 at 1× (main) · 2: 1920 × 1080 at 1.25×.

Get screen looks up one display and stores what it knows about it: where it sits, how big it is, how many pixels it packs into a point, and how fine it is. A macro then places windows and the pointer relative to the screen it is on, whatever the monitor setup.

Settings

Section titled “Settings”
Setting What it does
Which screen The main screen, A screen by number, The foreground window’s screen or The screen under the pointer.
Number For A screen by number: its 1-based number. Placeholders work.
Remember as The variable’s name, see below.
Scope This run keeps the variable to this macro, Everywhere shares it with all macros. See variables.

The editor lists the screens as they are right now, with their sizes and scales, so you know which number is which.

How it runs

Section titled “How it runs”
  • The variable gets the screen as a JSON object, and each field alongside it: name.number, name.x, name.y (its top-left corner, in the coordinates Set window and Mouse sequence use), name.width, name.height, name.scale (pixels per point: 2 on a Retina display, 1.5 at 150 % on Windows), name.dpi (physical pixels per inch, 0 when the system does not say), name.primary (true or false) and name.count (how many screens there are).
  • Screens are numbered as Windows’ display settings number them; on macOS the main display is 1 and the others follow left to right, top to bottom.
  • A screen that does not exist (a number too high, no foreground window) is logged and the variable and its fields are set to an empty text.
  • The action is instant.

Example

Section titled “Example”

Put the pointer in the middle of whichever screen the pointer is on, then click:

  1. Get screen, The screen under the pointer, Remember as s.
  2. Run script: vars.cx = String(Number(vars["s.x"]) + Number(vars["s.width"]) / 2); vars.cy = String(Number(vars["s.y"]) + Number(vars["s.height"]) / 2);
  3. Mouse sequence: Move to {{cx}}, {{cy}}; Click.
