Hi
I am not familiar with congatec board, but for i.MX6DQ SabreAI one can try
attached patch, sending the same IPU DI content to LVDS and HDMI.
IPU0 DI0 drives both LDB and HDMI.
Video parameters should be: video=mxcfb0:dev=ldb,LDB-XGA,if=RGB24 ldb=sin0
video=mxcfb1:dev=hdmi,1024x768@60,if=RGB24
Best regards
igor
