Screen.resolutions

Description

All full-screen resolutions supported by the monitor (Read Only).

Unity returns the resolutions the monitor supports and sorts them by width and then by ascending resolution. The Screen.resolutions always contain Resolution.refreshRate at 60 Hz (60 fps). Setting QualitySettings.vSyncCount to zero will allow the game to run as fast as possible. Normally one is used.

using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        Resolution[] resolutions = Screen.resolutions;

        // Print the resolutions
        foreach (var res in resolutions)
        {
            Debug.Log(res.width + "x" + res.height + " : " + res.refreshRate);
        }
    }
}
