Hi Guys, I've recently built a ambilight setup for passthrough using the following - Raspberry Pi 3 B+ - OSMC as operating System - Latest version of hyperion and hyperion config tool - WS2801 LED's ( about 3 M ) - HDMI splitter - HDMI to AV - USB Video Grabber (Fuschia ChipSet UTV 007) I did have to reduce the video settings on one device ( Firetv cube ) from 4K down to 1080p @ 60hz to get the screen grabbing to work....otherwise I just saw rainbow effect behind screen. Everything seems to be working good but the colors seem to be quite muted and dull. It seemed to be ok/better with the colors when using the internal grabber and Kodi checker enabled. Using static images on screen to adjust the colors seemed to work great but the range of the colors when playing a video through internal grabber or setup for passthrough using the USB grabber is not great. I can share my hyperion config file later this afternoon when I get home, but perhaps someone has some suggestions as to what values to change to get the best color from the led's?
