Adjust the overscan on the projector?

It's definitely not the projector. Netflix on the Shield is the only scenario that results in the thin green bar. The projector was used with a Raspberry, a Chromecast, a S905X box, a Zidoo X8 box, and an Xbox One S. The problem never occurred with any of those devices with any app. On the Shield, it's only Netflix and the it was already existing on the old Shield. Just thought someone may know about it.

I was able to fix the Netflix problem by switching from YCbCr 4:4:4 to YCbCr 4:2:2. On closer examination, grey scale performance also seemed slightly improved with 4:2:2 in Kodi, as in more visible shadow detail. Is that a known issue?
