Ok, thanks  ..I think that

Ok, thanks  ..I think that worked, but only with the tv directly hooked to the PC.  When the AVR was added into the mix the handshake wasn’t there when the AVR/tv combo was turned on after the PC was booted.

So the tv is always energized, even when in standby and so the PC maintains the information.  However, when the AVR is connected that tv info is now lost as the AVR was not “On” in that particular HDMI mode.

But then I dug a little deeper into the AVR options and found that by invoking HDMI Control ‘passthrough’ the system now works — the tv and AVR shake hands and so to with PC.  Hmm, I had never played with this feature set before.  

I can now turn on or otherwise switch the AVR/tv combination after the PC boots and my desktop (along with the sound) now appears on the Plasma tv.  An added bonus is that when the tv is turned Off in that assigned HDMI video mode, it also turns Off the AVR.  Conversely, when the AVR mode is turned on, so does the tv ..with the desktop.

Still, there remains a loose end that I’m curious about : without the “passthrough” invoked, if I go into CCC there is an option to Display Detect which will detect the AVR/tv combo and switch On the connection between them and the PC ..and that’s after the PC has booting up.  So process that works too.

So my question is, is there also a way to make the CCC autodetect the AVR/tv display either via a CCC feature switch (I can’t find any) or via a hotkey?  If a hotkey, where can the Display Detect command be found in CCC software?  This would almost be preferrable as the “passthrough” feature on the AVR constantly draws power as it is always On.
