Mine isn't a lightberry. I just use the usb video card plus the Pi. Also, an HD signal as input to the ambient light setup just isn't necessary. The software (or FPGA) is going to average pixel colors around the border to effectively reduce the resolution to match your LED spacing. With an HD signal, you're just spending more processing power/time to filter out and throw away more information.
