Hi, All.

In WEC 2013, we had a problem that HDMI output show a purple(or pink) line.

In Android, HDMI output was normal. So, we compared the HDMI part of Android and WEC 2013 BSP source code.

Referring to Android configuration, we modified to the HDMI initialization and configuration section in WEC 2013 BSP.
As shown below, the purple line disappeared in HDMI output.

We refered to the following file.

Please let me know if you have any questions.

Thank you.
