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