TV Screen Edge woes: 2 Fixes

[Ghost]

Your TV isn't showing the edges of the Pine64's Android screen, and that's vexing.   
    Android is unusable, or nearly so. Let's fix that, shall we?

    Method 1: Settings of your TV 
    You can adjust the settings of your TV.  You may have already tried and failed. Can it be done?

    Which menu and sub-menu?
    There's no standard method of organizing the settings of TVs. Many TV settings seem to 
    have been organized by confused rabbits running late. However, you should definitely try 
    these menus and sub-menus:

• Picture
  
• Video
  
• Advanced Video
  
• Screen
  
• Screen Adjustment
  
• Picture Size
  
• or who knows...
  

    What is it called?
    Look for any of these. The menu item could even be something else:

• Overscan
  
• Scan
  
• Screen Fit
  
• Screen Fill
  
• Format
  
• Title Safe / Safe Title
  
• Action Safe / Safe Action
  
• TV safe
  
• Aspect Ratio*
  
• Resolution*
  
• Size*
  
• Wide / Width*
  
• High / Height*
  

    *But avoid messing with these settings, if you can help it.

    What is the correct setting?
    The correct option could be:

• Just scan
  
• Dot by Dot
  
• 1x1 pixel ratio
  
• Full
  
• Fit
  
• Off / uncheck (for Overscan)
  
• On / check (if Underscan is an option)
  
• 4:3 (or even 16:9) *
  
• 1080p / 1080i *
  
• Auto / Auto Config
  
• or other options (experiment)
  

    So, expect to put in a little time and effort. Check all the sub-menus, and anything that could
    be a sub-menu, if you can't find it right away. It's probably there, somewhere, so look again.

    Method 2: Settings of Android
    If the above method doesn't work, or isn't ideal for you, here's a different way. (Using both
    methods, or going overboard with this one, would put a black frame around the edge of
    your TV screen.)

    In Android, go to Settings / Display / Screen scrap edge. Set width and height to ~96%.

    This method works on rooted Android 5.1.1 HDMI 20160505, found here. It does NOT work
    on RemixOS (yet, anyway), nor on Linux, OpenHab, etc. It's only for Android. I haven't 
    confirmed it to work on unrooted Android, but it probably does.

    Apply this fix every time you change to a different image of Android.

    I hope this helps. 

Thanks, NexusDude. I will sticky this.
