Issue: Blacks showing as grays
Fix: Add following to autostart.sh:
DISPLAY=:0 xrandr --output HDMI1 --set "Broadcast RGB" "Full"

This leads to an too dark picture, try a dark movie like Zero Dark Thirty and u will see...way too much detail lost due to Black

It may not work on your display (either it doesn't support full range RGB, or it ignores the quantization field in AVI infoframes). It is a good easy fix for those whose displays support this.

This is not needed if you have a recent kernel with https://bugs.freedesktop.org/show_bug.cgi?id=71769 fix. It is in recent OE nightlies.
