Hi All.
I made a custom board with an i.MX6 CPU.
And ported Android 6.0 and Windows Embedded Compact 2013(WEC 2013).
In Android, Both LCD and HDMI output is normal.
In WEC 2013, the LCD output is normal, but the HDMI output show a pink line as shown in the following figure.
Pink line is inside the blue square(left edge).

The width of pink line is 2 pixels at any HDMI resolution(such as 1280x720, 1920x1080, Etc.).
I want to remove the pink line from the HDMI output.
Please let me know how to fix above problem.
Thank you.

Hi Minsung

Currently there is a limitation with hdmi driver that timings are not sully recognized at different resolutions, the issue you are experimenting might be the case. However the purple line is fixed in the 474 release bsp of our third party GuruCE you migh try to contact them for support:
