但改變分辨率時，發送廣播即可：

?? ?Intent intent_outputmode_change = new Intent(ACTION_OUTPUTMODE_CHANGE);
??? ?intent_outputmode_change.putExtra(OUTPUT_MODE, outputmode_entries_logic);
??? ?intent_outputmode_change.putExtra("cvbs_mode", 1/0);?????
?????this.getContext().sendBroadcast(intent_outputmode_change);

分辨率顯示outputmode_entries_display和取值outputmode_entries_logic：

如果setting沒帶處理，需要自己做：

settings源碼的文件：

OutputSettingsBroadcastReceiver.java 改變分辨率。

HDMICheckHandler.java 自動檢測hdmi最佳分辨率。

?

位置坐標文件，實現屏幕放大，縮小： /sys/class/ppmgr/ppscaler_rect： x:58,y:29,w:1280,h:720

分辨率文件： /sys/class/display/mode ： 1080p
