Hi all
I've recently setup a strip of WS2801 LEDs around my telly using an RPi3 + OpenELEC + Hyperion and it looks amazing!
I used the guide on this website to help me get everything configured, including a video grabber so I could use an alternate HDMI input (specifically my Playstation 4) as the source for the LEDs:

It all works great, until I turn off the PS4 so that the video capture card has no input. Obviously at this point I would like all of the LEDs to switch off, however they currently go to a very bright blue. Capturing a screenshot from the video capture card when this happens shows a blue screen with "NO SIGNAL INPUT" (or something similar) in white text at the top left of the screen.
I've tried adjusting the blueSignalThreshold in the config for the grabber as described in the github issue here:
https://github.com/hyperion-project/hyperion/issues/45
I have not been able to get the LEDs to switch off however (I wonder if the "NO SIGNAL INPUT" text is just enough white near the edge of the screen to just be under the threshold), and currently have to switch them off at the mains whenever I turn off my PS4 (or using the android app to turn the LED brightness to zero). Hoping someone will be able to guide me towards a solution... thanks in advance!
Keep up the great work on the project
Cheers
Jim
