Setting resolution not working

ladron · July 2013

I'm having trouble changing the resolution of my game. Even the SceneSetResolution example that comes with the Unity plugin doesn't work.

Instead of re-sizing the screen, it just changes the draw area. In other words, if you set a smaller resolution than 1080p it stays at 1080p, but draws in a smaller window in the upper left.

Does anyone else have this working?

Your tv needs to be capable of changing the resolution.

If you can run adb commands try:

adb shell

su

am display-size 1280x720

am display-size 1920x1080

(Try changing to 720p)

setprop persist.tegra.hdmi.resolution 720p

(switch from the play screen to the launcher screen)

Thanks for the reply, Tim. So I guess setting the resolution explicitly should be discouraged, then, since it won't work on some people's TVs?

On a related note, will the Unity resolution always be 1920x1080 by default, regardless of the actual TV resolution, or will it be 1280x720 if the TV is 720p?

You can check the actual display resolution in Java like this:

int getDisplayWidth() {

WindowManager windowManager = getWindowManager();

Display display = windowManager.getDefaultDisplay();

Point size = new Point();

display.getSize(size);

return size.x;

}

int getDisplayHeight() {

WindowManager windowManager = getWindowManager();

Display display = windowManager.getDefaultDisplay();

Point size = new Point();

display.getSize(size);

return size.y;

}

Ok, here are my latest findings on setting the screen resolution:

Doing the following:

Screen.SetResolution(1280, 720, m_fullScreen);

OuyaSDK.OuyaJava.JavaSetResolution("1280x720");

results in the Ouya still running at 1920x1080 with Unity rendering in a smaller, 1280x720 window in the upper left corner of the screen.

I'm guessing that if the Ouya is connected to a TV that only supports 720p, this would look fine, but it obviously won't work for 1080p displays. I'm also guessing that if the Ouya is running at 720p, you'll get an 1280x720 window anyway without doing anything, but I'm not sure.

If I change "android:anyDensity" to "false" in the android manifest, then Unity runs at 960x540 (half 1080p). I haven't found any way to force 720p.

Using the display object we should be able to check if the TV can actually change to that resolution or change to it.

It's a bit dumb that the emulated size isn't centered.

I found this:

"For now, if you're using a Java full-screen SurfaceView (e.g. GLSurfaceView), you can reduce the size of the surface you use which gave us a frame rate boost in our test app. For example:

surfaceView.getHolder().setFixedSize(1280, 720);"

over on this thread.

I'm pretty sure that's just changing the size of the view and stretching. It's not actually changing the resolution of the TV. You have access to the UnityPlayer in the UnityPlugin.java to maybe access the surface view.

Howdy, Stranger!
