How to save overscan setting?

thuanho — Sat, 16 Feb 2013 00:05:18 GMT

Under Settings -> Display -> Advanced Display, there is an option for Width/Hieght OverScan. After a reboot, this setting isn't saved. Does anybody else have this issue? Is there a way to preserve this setting?

Thuan,

This is an issue my company is investigating as well. We have been told that Freescale is aware of this issue and that they are investigating it, but it is a low priority issue. If your primary display is HDMI, this is not what you want to hear. We are attempting to mod the BSP ourselves to implement this capability. A workaround that you might attempt for this issue involves modifying the Launcher app and hard coding overscan values that work for your device as below:

private static class PendingAddArguments {

int requestCode;

Intent intent;

long container;

int screen;

int cellX;

int cellY;

}

//add these definitions for overscan workaround

private static final int MAX_DISPLAY_DEVICE = 6;

private DisplayManager mDisplayManager;

….

if (PROFILE_STARTUP) {

android.os.Debug.startMethodTracing(

Environment.getExternalStorageDirectory() + "/launcher");

}

//overscan workaround

mDisplayManager = (DisplayManager)getSystemService(Context.DISPLAYMANAGER_SERVICE);

for(int i=0; i<MAX_DISPLAY_DEVICE; i++ ) {

mDisplayManager.setDisplayXOverScan(i, 6);

mDisplayManager.setDisplayYOverScan(i, 6);

}

The key is calling the display manager class. You will probably need to set a value other than six for x and y overscan.
