setup: Comcast cable box Motorola DCX3400-M; Denon AVR991; Panasonic monitor TH 42PH9UK with HDMI terminal TY-FB8HM.
connected all with HDMI cables. Result no screen. connected cablebox directly to monitor with HDMI: screen! Connected HD camcorder with HDMI to Denon and Denon with HDMI to monitor: no screen. Panasonic informs me that HDMI terminal in monitor is not compatible with HDMI 1.4a (Denon). How does that relates to HDMI.org remark that HDMI protocols are backward compatible?
