[meta-freescale] HDMI on i.MX6

I have some questions about HDMI display on i.MX6, the
SabreLite / Nitrogen6x in particular.
When I boot with my HDMI monitor attached, U-Boot finds it
and tells me:
auto-detected panel HDMI
Display: HDMI (1024x768)
Then Linux is booted with these arguments:
video=mxcfb0:dev=hdmi,1280x720M at 60,if=RGB24
I know that these parameters come from the boot script, but
they seem to be hard coded. What if I wanted different display
parameters? These values don't seem to work very well for my
monitor - stuff is being cut off on all edges. Perhaps my
monitior isn't the best so I'd like some guidance on how to
tune things. I've attached a picture of the actual screen
so you can see what I mean.
Thanks
