Multiple duplicates problem in resolutions

I am trying to do a resolutions manager and everything works pretty well, except the fact that every resolutions appears multiple time in the dropdown...


I tried via code to delete the duplicates, but it doesn't work and I absolutely don't understand why.

Code (CSharp):

1. public class ResolutionsManager : MonoBehaviour
2. {
3.  
4.     public Dropdown resolutionDropdown;
5.  
6.     public Resolution[] resolutions;
7.  
8.     public Resolution[] resolutionWithDuplicates;
9.  
10.     // Start is called before the first frame update
11.     void Start()
12.     {
13.         resolutionWithDuplicates = Screen.resolutions;
14.  
15.         List<Resolution> resolutionList = new List<Resolution>();
16.         foreach(Resolution resolution in resolutionWithDuplicates)
17.         {
18.             if(!resolutionList.Contains(resolution))
19.             {
20.                 resolutionList.Add(resolution);
21.             }
22.         }
23.  
24.         resolutions = resolutionList.ToArray();
25.  
26.         resolutionDropdown.ClearOptions();
27.  
28.         List<string> options = new List<string>();
29.  
30.         int currentResoltionIndex = 0;
31.  
32.         for(int i = 0; i<resolutions.Length; i++)
33.         {
34.             string option = resolutions[i].width + "x" + resolutions[i].height;
35.             options.Add(option);
36.  
37.             if(resolutions[i].width == Screen.width && resolutions[i].height == Screen.height)
38.             {
39.                 currentResoltionIndex = i;
40.             }
41.         }
42.  
43.         resolutionDropdown.AddOptions(options);
44.         resolutionDropdown.value = currentResoltionIndex;
45.         resolutionDropdown.RefreshShownValue();
46.     }
47.  
48.  
49.     public void SetResolution(int resolutionIndex)
50.     {
51.         Resolution resolution = resolutions[resolutionIndex];
52.         Screen.SetResolution(resolution.width, resolution.height, Screen.fullScreen);
53.        
54.     }
55. }

Does anyone has an answer ?

 

Unity's Resolution object has 3 fields: https://docs.unity3d.com/ScriptReference/Resolution.html

• width
• height
• refreshRate

Maybe your "duplicates" actually have different refresh rates. Try printing the resolutions with the provided ToString method to check: https://docs.unity3d.com/ScriptReference/Resolution.ToString.html. E.g.:

Code (CSharp):

1.             string option = resolutions[i].ToString();

 

Thank you so much, that was the issue.

It's really optional, but is there a way to remove the "@" (not really important, but if you know).

 

build your own string using the three values, like you were doing before. Just include the refresh rate this time.

 

Thank you very much

 

hey, i have the same issue just that i dont know where to put that line of code, (i have the exact same code as him)
