boundary box test pattern in ADV7182A the right vertical line is not visible at all

We are using ADV7182A in our custom board. When we run the Free run mode with Boundary box test pattern we are not seeing the white border pixel on all the four sides. We are seeing it only on the left and top side of the display. Is there any configuration missing
