Hi all. I'm considering upgrading some of my equipment pretty soon. I've got my eye on Oppos new UHD BD player, and the new Epson 4K projector. I kinda like my old Denon AV amp though. But it can't pass 3D or 4K. So devices like the Oppo are designed to slot into legacy systems like mine. The twin HDMI outputs! The 'audio only' output goes into the amp to let it do it's thing, (lets call it "BD Audio" on the amp) and the video output goes to your display, right? Could I split that 4K 'video out' feed and send one feed to the projector (obviously) and send the other feed back to the amp, (lets call it "BD Video", on the amp)? Obviously I wouldn't select the "BD Video" input if the Oppo was doing any 3D or 4K shenanigans, only if it was playing back regular BD playback. We only use 3D on the projector, so can lose 3D capability to the TV (which is what I currently use a HDMI splitter for: to split a Panasonics 3D output between a TV and projector, both 3D capable: no problems there. Basically, does a HDMI splitter 'see' a HDMI input on an amp, if that input is not selected? Or are they all 'live' whether selected for use or not? Will that unselected HDMI input still send out a signal that stops the 3D/4K signal going to the projector? I know it's a long shot, and that all this 4K and HDCP business is an utter nightmare. But I'd appreciate your thoughts. It's a shame that the Oppo can't switch that secondary HDMI output between just audio and audio/video (my Panasonic BT310 can!) but it can't. So I was wondering about splitting the full video feed, with one split going back to the amp... Any ideas good people?
