imx6q video display problem

Hello,  I want to preview my video on HDMI LCD,   my cmos sensor is 8 bit grayscale, 752x480.  and I tested it with mxc_v4l2_overlay.c  from imx_test package.  

 

I find the image show in LCD  in not the same as the sensor output,  i.e. smaller , copied to 16 same images,   green background!   (see the attachment)

 

I want to know if  grayscale image direct preview is supported by imx6q?   if yes, how should I modified the driver(I have modified the driver for capture grayscale sensor image, but not for preview)?

or do I have to first  capture it to mem,then output to LCD (mxc_v4l2_output.c)?

 

thanks a  lot !
