Resolution

Ok, I need help understanding what's going wrong here. I am trying to get this app that I am building
on a PC to load on a Sony Tablet S which has a resolution of 1280 x 752 for the displayable area.
I think that I don't understand the game window sizing or something, because I can't make the
connection between it's size and the placement of the GUI elements. I need help because I am tired
of uploading test builds to have someone else check for size and placement when I really just need
to understand what is going wrong so I can fix it. Here is some of the code that I am using so you
can see how I am approaching it and maybe tell me how to set things up so they appear properly
on the target device:

Code (csharp):

1.  
2. // I am creating this on a 1680x1050 monitor.
3. // I am not sure how to set the game window to show things how they will appear on the target device
4. // I tried free aspect with it set to 1280x752 and I have tried 16:10 ratio but neither come out right
5.  
6. // Native resolution metrics
7. public static float native_width = 1280;
8. public static float native_height = 752;  
9.    
10. // Target resolution metrics
11. private int m_height;
12. private int m_width;
13.    
14. // Resolution scaling factors
15. float rx = Screen.width / native_width;
16. float ry = Screen.height / native_height;
17.  
18. // This is the button that I am testing positioning with
19. private Rect _ButtonRect = new Rect(Screen.width/2 + 400,Screen.height/2 + 200,198,147);
20.  
21. // START
22. void Start () {    
23.  
24.     // Set Resolution
25.     m_height = DisplayMetricsAndroid.HeightPixels;
26.     m_width = DisplayMetricsAndroid.WidthPixels;
27.        
28.     Screen.SetResolution(m_height, m_width, false);
29. }
30.  
31. // ON GUI
32. void OnGUI() {
33.  
34.     GUI.matrix = Matrix4x4.TRS (new Vector3(0, 0, 0), Quaternion.identity, new Vector3 (rx, ry, 1));
35. }
36.  

Again, the goal is to be able to place my GUI elements on my game window as I want them to look
on the tablet. I use the GUI scaling matrix to set them to the resolution of the target device. But, the
screen is either squished or the GUI elements are out of place to the left and upwards. I really need
an expert on this to get me squared away please.

I think I need to get the game window set up to show exactly as they will appear on the target device.

The build looks like this:

But the result on the tablet looks like this:

It seems to me that the device is at a lower resolution and the GUI are sizing to that,
but when I adjust the resolution using these metrics :

// Set Resolution
m_height = DisplayMetricsAndroid.HeightPixels;
m_width = DisplayMetricsAndroid.WidthPixels;

// In the start method
Screen.SetResolution(m_height, m_width, true);

The entire screen gets squished like this:

Can someone please explain what is going on here before I lose all my hair?

 

Can anyone help me understand the relationship between the game window and what shows
on the target device? I want to see what I have on my screen while I'm creating the game also
on the device that I build it for. I am not making the connection.

 

If you select "free aspect" in drop down menu of editor window you can resize the editor. Then save the size when you get it right (you know by position guiTextures to edges of screen until they fit just right in editor window and also device). I could only get the width of my tablet im deploying to (1280) but not the height (800). Hope this helps a little bit.
