I recently got my Ambilight working through my RPi 3 and installing the latest version of Hyperbian on it. Now I have two issues: 1) There is a small delay (0.2 - 0.4 secs) between the image on the screen and the leds (that is, the leds are lagging behind). Are there settings in Hyperion that I can use to tweak this? BTW. The cable from my RPi to the leds is approx 1.5 meters, but I can't imagine that this would be too long. Please correct me if I'm wrong. 2) When the TV and all sources are switched of and all should go to idle state then the leds are going to a certain state, (various colors) while in the Hyperion configuration I indicated that no effect should be made. What can I change to make sure the leds are powered down whenever there's no input signal?
