Issue: Black Bars on both Sides of the TV screen while watching in 3D mode. This is applicable only for 3D TV models


 Black Bars & Garbage effect are algorithm to increase 3D effect.


Reasons for the same are :

① L/R image is synthesized and showed as 3D image.

② adjusting L/R image makes blank image

③ Black bar/Garbage area 


                  <3D adjustment>                    <3D effect adjustment + L.R synthesis>


Note : It is not a defect. please wear 3D glasses to watch image.


1) press my app button  on remote while watching3D setting ▷ if 3D mode is set as 'user setting',

   →  change to standard, sports, movie, extreme etc.


2) if 3D mode is 'user setting', and 3D effect is adjusted then, 

  →  adjust 3D effect to low & black until the bar disappears.
