screenresolution is a simple, cross-platform Go package library used to detect the current screen resolution. It follows the UNIX philosophy of doing one thing and doing it well.

It supports Windows, Linux and MaxOS.

package main

import (
	"fmt"
	"os"

	"github.com/fstanis/screenresolution"
)

func main() {
	resolution := screenresolution.GetPrimary()
	if resolution == "" {
		fmt.Println("failed to get screen resolution")
		os.Exit(1)
	}
	fmt.Println(resolution)
}

screenresolution can only get the resolution from the default (primary) display. A future update will add support for getting the resolutions of all attached displays.

On Linux, libx11-dev is required.

sudo apt-get install libx11-dev
