    NUC6i7KYK - Windows 10 - HDMI Handshake after TV power cycle


      I've got a Skull Canyon NUC running Windows 10 (1607).  HDMI 2.0 cable running from NUC to Onkyo TX-NR656 receiver.  From the receiver to an LG OLED 4K TV (HDMI 2.0).


      If I put the NUC to sleep and power off the receiver/TV, then power the receiver/TV back on, and wake the NUC, HDMI re-handshakes and I get the login screen for Windows.


      However, if I power off the receiver/TV leaving the NUC up and Windows running, then turn on the receiver/TV I get a "No Signal" and the TV sits there on a waiting for input screen.  Seems like HDMI doesn't re-handshake.  The only way out is to press the power button on the NUC which tells Windows 10 to power off.  Then power the NUC back on and everything comes to life.


      Summary:  Windows 10 (1607), wake from sleep works on Onkyo and LG TV.  Doesn't work if Onkyo and LG TV are powered on while NUC is awake.


      On latest drivers from Intel Download (BIOS, Chipset, Iris Graphics, HDMI 2.0 firmware).
