Bug with screen.resolutions that is working only on the editor :/

[TeKGameR]

Hi guys, i have a problem with Unity 2017.1 as you can see on the screen my simple testy code with
screen.resolutions isnt working

Look in editor and Build

(Editor work properly and Build print the same resolution ~3times)

 Rect winRect;

    void OnGUI()
    {
        winRect = GUILayout.Window(0, winRect, OnWindow, "Resolutions");
    }

    void OnWindow(int ID)
    {
        GUI.DragWindow();
        GUILayout.BeginVertical();
        foreach (Resolution R in Screen.resolutions)
        {
            GUILayout.Label("Res: " + R.width + "x" + R.height, GUILayout.MinWidth(200));
        }
        GUILayout.EndVertical();
    }

This is a known bug: Screen.resolutions returns duplicate entries on Unity 5.5.3 - Unity Engine - Unity Discussions

Uh i’m not the only one ^^ Do you know how to fix it?

[EditorBrowsable(EditorBrowsableState.Never)]
[Obsolete(“Property GetResolution has been deprecated. Use resolutions instead (UnityUpgradable) → resolutions”, true)]

I think this bug appear when unity was switching method to get screen resolutions

Uh i’m not the only one ^^ Do you know how to fix it?

I literally posted a code solution in that thread

[TeKGameR]

Uh so it doesnt work for me

Its still doing the same on the editor and the build

Here is the code:

 void Start()
    {
        StoreAvailableResolutions();
        for (int i = 0; i < availResolutions.Length; i++)
        {
            ScreenResolution.options.Add(new Dropdown.OptionData() { text = availResolutions[i].width + "x" + availResolutions[i].height });
        }
    }

    static string[] resPresentation;
    static Resolution[] availResolutions;
    /// <summary>
    /// Caches a unique list resolutions available on the currently active display
    /// </summary>
    public static void StoreAvailableResolutions()
    {
        // process only resolutions above 1024x768
        var resList = UnityEngine.Screen.resolutions;
        // for some reason Unity contains duplicate entries for available resolutions so grab only unique ones
        var unique = new Dictionary<string, Resolution>();
        foreach (var res in resList)
        {
            unique[res.ToString()] = res;
        }
        // sort unique keys by comparing width and then height of their representative resolutions
        var sortedKeys = unique.Keys.ToList();
        sortedKeys.Sort((a, b) => {
            int diff = unique[a].width.CompareTo(unique[b].width);
            if (diff != 0) return diff;
            return unique[a].height.CompareTo(unique[b].height);
        });
        availResolutions = new Resolution[sortedKeys.Count];
        resPresentation = new string[sortedKeys.Count];
        for (int i = 0; i < sortedKeys.Count; i++)
        {
            resPresentation[i] = sortedKeys[i];
            availResolutions[i] = unique[sortedKeys[i]];
        }
    }

Here is screens of what it does i read the code and it should work

[KelsoMRK]

Are you sure those aren’t actually the same dimensions with different refresh rates?

[TeKGameR]

Nope already checked

[TeKGameR]

Uh okay its what you said but my text setup wasnt showing me the @ 60Hz… sorry But do you know how to only print resolutions without their 60Hz, 70Hz i really want a list with every resolutions and no duplicates because i use
Screen.SetResolution(800,600,fullscreen,HERTZ)

Please

[KelsoMRK]

Don’t use ToString() when creating the dictionary entries. Just combine width and height like you do in the dropdown

[TeKGameR]

Thanks it work I love you :)

static string[] ressolutions;
    public static void StoreAvailableResolutions()
    {
        var resList = UnityEngine.Screen.resolutions;
        var unique = new Dictionary<string, Resolution>();
        foreach (var res in resList)
        {
            unique[res.width+"x"+res.height] = res;
        }
        var sortedKeys = unique.Keys.ToList();
        sortedKeys.Sort((a, b) => {
            int diff = unique[a].width.CompareTo(unique[b].width);
            if (diff != 0) return diff;
            return unique[a].height.CompareTo(unique[b].height);
        });
        ressolutions = new string[sortedKeys.Count];
        for (int i = 0; i < sortedKeys.Count; i++)
        {
            ressolutions[i] = sortedKeys[i];
        }
    }
