Yeah sreekant.. I tried to change settings. But none of them worked for me..
Under TV settings, I set the settings as follows.
TV Screen Size - 16/9
TV Screen Aspect Ratio - Streched/Zoomed/Pillar Box
But none of them worked. Even Pillar Box is not showing the full image but the black pillar box are appearing at the left and right side.
Is there any new settings available in your new software version? Mine is still the older version.
