I am using ADV7842 VGA Interface in one of my custom design. I am using ADV7842-VER.5.9c_AVEB.txt  Supported scripts to configure ADV7842.

I am able to detect all VGA Supported standard formats.

But, I am facing a problem with video alignment. I am unable to see total video content,  edges are missing  for (Bottom,Top,Right and Down) sides of all vga sources video content .



All the Commercial displays has Auto Adjustment Feature. Similar to this

Is ADV7842 -VGA Interface supports Auto Adjustment  Feature ?

if not Can anyone suggest a forward to resolve my issue(Where Edges are missing for All VGA Supported video formats?)



Thanks & Regards,
