    HDMI-CEC Wake/Color Gamut Problem....?


    This isn't a 'new' issue. I honestly thought it was just my cheap TV, but now I wonder...

    Every time I power on my console (Energy Saving Mode), and the console turns on the TV (also in Energy Saving Mode) via CEC, the color gamut of the Xbox->TV is WAY off. Blues are Reds. Reds are Blues.

    Restarting the TV fixes the issue. Or of the Xbox initiates a new handshake by switching formats.

    I think something in the handshake is off or mistimed on startup. I've tried multiple cables, but the problem persists. I'll upload an image... It's pretty weird.

    Anyone else experiencing this issue?

    Partial HDR support for LG TV?

    I tried connecting the Xbox directly to the TV with the included cable, same results. So it's not the receiver.

    Deep Color and Wide Color Gamut are enabled on the TV, aspect ratio is at Just Scan, every else is set according to what the Xbox calibration tool recommends. TV picture mode is set to ISF Expert1, which is needed to unlock most options suggested by the
    calibration tool.

    Anything else I should check? There's no HDMI enhanced, or anything like that. Just HDMI Deep Color. AFAIK that's all the LGs need.

    Xbox One Passthrough work when off?

    I don't know what anynet is, nor do I know if "HDMI control" and HDMI-CEC are the same thing, but HDMI-CEC is supported according to MS.

    One Guide and Windows Media Center PC (HTPC)

    Most PC Graphics Cards if any Do Not Support CEC so it's unlikely you will be able to change channel using Windows Media centre via HDMI. You can However buy CEC adapter like this. www.pulse-eight.com/.../usb-hdmi-cec-adapter
