I don't it is overscan.

It looks like it has a white glare on the screen.
And this is only on the Chromebox.

dude, we can't help you if you refuse to provide any real information about the problem. The wiki entry on color range selection also has a test video and a picture showing you the correct output. Perhaps you could use that as a reference and then try describing how yours deviates from the correct output?

and I hope you've tried connecting the ChromeBox to your TV directly, to rule out your receiver as the problem (reporting incorrect color space, for example).
