    SplitDeck 4K HDMI 2.0 Splitter by Sewell
    2-port Distribution Amplifier, 1x2, 4K at 60Hz, HDR, 3D, HDCP 2.2, 4:4:4 Chroma

    Their obnoxious guy on chat (Logan) says that it will.

    But most people here, and on AVSforum, say that the cheaper hdmi splitters will NOT split hdmi and then feed my TV the full 4K signal.

    Who's right?

    I'm in the market for this type of solution as well, and I've about given up, that due to HDMI complexities it's easier just to buy a new receiver every time HDMI is upgraded.

    I think that, with the splitter, HDMI will negotiate the video signal down to the least common denominator between your TV and your receiver, meaning that you'll end up seeing 1080p on the TV because that's the best your receiver can do, even if your TV supports 2160p. That page you linked to even talks about this in the context of 1080p v. 720p, saying you need a downscaler on the receiver side of the splitter. But I wouldn't depend upon this sort of Frankenstein's-monster setup working that well if at all. E.g., even if you come up with a string of boxes that somehow works, you'll end up having audio/video synchronization issues (audio will be a few milliseconds behind the video).

    This "market solution" of integrated audio, video, and DRM is in this instance resulting in hugely wasteful premature obsolescence. The solution within the context of HDMI would be for a new HDMI standard to include an arbitrary bitstream audio return channel (ARC) instead of one that is limited to S/PDIF quality audio from the DVD era--but of course you'd need a new TV and receiver to support such a hypothetical standard.

    Hey Scott911,

    That device will not work for what you are trying to do.

    This one will do exactly what you are trying to accomplish. (4K HDR to TV and Audio to old AVR)
