I have a greenish output on 4k content and on all Tivo menus are green after enabling 4k in the video setup. The Bolt is connected to a 4k Sony XBR-75X850C which is HDMI 2.0 compliant on all ports and is running the latest firmware. I am using the supplied HDMI 2.0 cable and am able to display 4k content from several other sources correctly. I returned my first unit and the second Bolt is doing the exact same thing. "HDMI Status" in system info says "HDCP 2.2 enabled". Any ideas?
