ADV7619 pink lines after switching from unsupported to supported resolution

Hello,

 

I have run across an issue where I get what appears to be, two vertical pink lines in my output.  Both lines appear on the left side of the image, as shown in the attached screen capture.  What causes this is the following steps:

 

Setup:

 

ADV7619-ADV7511 evaluation board, running 02-08 720p, 1080i, 1080p In - 36-bit RGB 444 Out (ADV7619-VER.1.7.c.txt) script.

 

1.  Set HDMI input to 1920x1080p @ 60Hz -> Image appears as expected

2.  Set HDMI input to 1920x1080p @ 120Hz -> Image does not appear as expected (assuming not supported by settings)

3.  Set HDMI input back to 1920x1080p @ 60Hz or any other resolution supported by the script -> Image appears as expected, but with the pink lines.

 

The pink lines will disappear once the resolution is switched again to another supported resolution.  I should also note this happens with the repeater software running as well, as well as my own system which is an ADV7619 -> FPGA -> ADV7511.  On my system the video contains the pink lines before it reaches the ADV7511.

 

So I am wondering if there is are additional setting I need to prevent this?  I can't really control what input the user puts into the system, even if its not supported, so I would be nice to avoid this.  Any ideas would be appreciated.

 

Thanks!
