1920x720 display problem with Qt embedded system

[aktay]

Dear all,

I am running qml applications on IMX6. I have a 1920 x 720 resolution screen.But the objects appear to be flattened from the top.
The screen works fine when I connect my PC.

U-boot display conf (for HDMI):

setenv my_bootargs_sata setenv bootargs console=\${console},\${baudrate} root=/dev/sda2 video=mxcfb0:dev=hdmi,1920x720M@60,if=RGB24

Any ideas on this subject?

Thanks.
