Question about a menu options on d5 mark 2

[SilverBullet07]

On the camera menu "playback 2' (blue) there is a option called AF Point display.

On page129 of the manual, it states if set to enable the af point will be displayed in red.

If it is disabled what does it do because I can't see any difference? Both options highlight the focas point. Is disabled just a different color? I'm colored blind and maybe can't see the difference.


Thanks

Figured it out....The focus point shows up on playback or viewing the image on the display to see what you had focused on. That's a good feature specially when something might be off and you want to see just what you focused on...
