Dear Mr Laurent,

Thank you for your quick reply.
This is the log file contains information about the command "modetest -M
rcar-du" (with the HDMI cable plugged).
Thank you. I think I know what's wrong. The default mode picked by the system
in your case uses positive H/V sync polarities, while in my cases the sync
signals have negative polarities. Could you try to select 1024x768 @60Hz
instead of 1024x768 @75Hz ? I think the HDMI output would then work correctly,
which would confirm that the problem is indeed caused by sync polarities.
Dong is sick, so he did not attend today. He will reply to you tomorrow.
Could you explain more how to set 1024x768 @60Hz and negative polarities for the HDMI output?,

Thank you!.
Hiep.
