create apk that modifies display ouput

I can describe to you the problem, and looking for a solution hopefully through an apk. You can see the pics attached to get an idea 1. we have an android box running Android 4.2.2 , the box has both hdmi and rca output. (pic: [login to view URL]) 2. When you plug in the box via rca cables, the box always defaults to (PAL) format giving this colorful screen, since my location is only NTSC (pIc: [login to view URL]) 3. Now you can change the settings in android settings > display output to (NTSC), however this is virtually impossible since the screen looks like a rainbow (pic: [login to view URL]) This only occurs when the rca output is used, when we use hdmi we get no error . So i need an apk that can either default from PAL TO NTSC, or if possible an apk that can change the ouput to NTSC by using a keyboard and typing "000" or something
