Golang : Detect number of active displays and the display's resolution



Tags : golang detect-resolution monitor screen-capture height width

There are times when we need to find out the number of active displays and their resolution. The following code is a simple program that utilized the kbinani/screenshot package to get the active screens' information.

The information will allow our program to properly capture screenshot or adjust our program output - such as maximizing(fullscreen) to the entire display.

Here you go!


 package main

 import (
  "fmt"

  "github.com/kbinani/screenshot"
 )

 func main() {
  n := screenshot.NumActiveDisplays()

  fmt.Println("Number of active monitor(s) : ", n)

  for i := 0; i < n; i++ {
 bounds := screenshot.GetDisplayBounds(i)

 x := bounds.Dx()
 y := bounds.Dy()

 fmt.Printf("Display #%d resolution is %d x %d\n", i, x, y)
  }
 }

Sample output:

Number of active monitor(s) : 2

Display #0 resolution is 1920 x 1080

Display #1 resolution is 1920 x 1080
