Thanks for the feedback. We will add an option to change the display resolution, right now, it's fixed at 1920x1080. It's a good suggestion to black out the background, will do that.
As for config file, if you change from the admin web interface, it should take effects immediately, if you modify it by hand, then need to restart the server. Which one is your case?
you can restart the server this way w/o rebooting:
sudo /etc/init.d/rplay stop
sudo /etc/init.d/rplay start
