Answer 1

I did some digging for you and found a way to get your screens width and height via command line in windows:

wmic desktopmonitor get screenheight, screenwidth

So all you have to do is execute this command in a Go program and print the output!

package main

import (
  "os/exec"
  "fmt"
  "log"
  "os"
)

func main() {
  command:= "wmic"
  args := []string{"desktopmonitor", "get", "screenheight,", "screenwidth"}
  cmd := exec.Command(command, args...)
  cmd.Stdin = os.Stdin
  out, err := cmd.Output()
  fmt.Printf("out: %#v
", string(out))
  fmt.Printf("err: %#v
", err)
  if err != nil {
    log.Fatal(err)
  }
}
