iMX6 Kernel 4.4 HDMI Resolution

I am using Yocto linux kernel 4.4 on wandboard. I have connected a Waveshare 7 inch HDMI 800x400 which is having a capacitive touch. This is my bootargs:

console=ttymxc0,115200 root=/dev/mmcblk0p2 rootwait rw video=mxcfb0:dev=hdmi,800x480M@60,if=RGB24,bpp=32
Now when the board boots, the right side part of the display is going out of screen i.e I am not able to see the full screen.Even from the splash screen,the image does not come in exact middle of the screen.It is shifting to right.
I am currently using the core-image-sato.
What changes do i need to do so that images come in between. Also when I see /sys/class/graphics/fb0/modes 
it is showing the following:

root@wandq:~# cat /sys/class/graphics/fb0/modes 
Can anyone help me regarding this?
