First thing u need to do is log on your NUC via ssh and generate a Startup Script as
described here :

http://wiki.openelec.tv/index.php?title=Autostart.sh

Here is step by step how to do it on a Mac..

Go to the Terminal, from there type :

ssh [email protected] (IP of ur NUC)

Then it will ask u for the password, which is : openelec

You should be logged in now.
Then type like stated in the Guide above :

echo "#!/bin/sh" > /storage/.config/autostart.sh && chmod +x /storage/.config/autostart.sh

This command makes the autostart.sh available and puts it in the right directory.

Next Command then is :

nano /storage/.config/autostart.sh

This should open up a new window (The Autostart.sh).

In the first line u should see :
#!/bin/sh

Under this u write this command :

DISPLAY=:0 xrandr --output HDMI1 --set "Broadcast RGB" "Full"




So in the End it should look like this :

#!/bin/sh
DISPLAY=:0 xrandr --output HDMI1 --set "Broadcast RGB" "Full"


Then Press CTRL+X, it will ask to safe, type Y (yes) and then press enter.

Now u should be back in the Terminal, still logged on ur Nuc....just Type "exit"
and close the Terminal.
Reboot ur NUC now and black should be (too) black again.
