+1.
I had a similar story with my new Panny 65VT50 which is now on HDMI-2 out of my V867, with my old Sony 34XBR960 on HDMI-1 out of the 867.
The 65VT50 accepts 1080p, but the 960 can only handle 1080i. The Oppo BDP-103 source device (on the other side of the 867) sees BOTH of these displays when HDMI 1+2 is in effect on the 867 and both TV's are on. So the 1080i resolution is "negotiated" in order to feed both sets simultaneously through the 867, if they're both on and I want to use them both.
If the Sony is powered off (i.e. in "standby") the 103 will send 1080p through the 867 and on to the Panny. If the Panny is powered off the 103 will send 1080i through the 867 and on to the Sony.
But if the Panny is already on (along with the 103 and 867) so that the 103 is sending 1080p to the Panny, and I then power on the Sony, there is another HDMI-handshake which occurs along with a repeat of the resolution negotiation, and this time the Sony requires 1080i so the 103 changes from its previous 1080p to now 1080i, to satisfy both the Sony and the Panny.
Now if instead of using the 103 (with its "smart" HDMI handshaking capability when it's the source) as the source device, I instead use a Linksys DMA2100 going through the 103's external HDMI input, the same type of re-handshake re-negotiation involving the 103 does NOT occur when I power the Sony on second. So the 1080p which was in effect (from the 103) for the Panny is not changed to 1080i to satisfy the Sony, and the Sony now presents a black screen (because it can't handle 1080p source).
Strangely, no amount of fooling around with the 103 and 867 can now trigger a reinitiation of the HDMI handshake so that the 103 drops back to 1080i from the originally determined 1080p. The only way I can reinitiate the HDMI handshake is to power off the Panny, OR... use the "HDMI OUT" button on the 867 to specify "HDMI 2" (instead of "HDMI 1+2"). And of course once the handshake is performed, the 103 decided on 1080i as the output and the Sony once again displays properly.
This HDMI multi-device-relay-chain combined with multi-display on the output side has always been problematic. It appears we humans can understand what results are desired far better than all of the hardware/software involved along the HDMI network chain.
And sometimes we just have to take matters manually into our own hands, or "simplify" things in the network as seen by the HDMI negotiators who remain involved. The HDMI OUT button on the 867 is exactly one way to simplify things when multiple displays with different characteristics are connected to both HDMI1 and HDMI2. And in virtually all situation using this button to designate WHICH HDMI display output is "live" (no matter that state of the other display and its HDMI visibility) is the correct and simplest solution. It gets the job done.
