Unfortunatelly in this past week no one has added any posts to this problem .. not even Clint or Gene who I invited to throw in the expert knoweldge. Hope some one replies to your thread.
Yes my testing (on 2600) has shown that there needs to be a connected display WHICH SENDS THE DISPLAY'S BASIC AND
EXTENDED EDID TABLE THRU DDC PIN 7 ON DVI PLUG BACK TO THE 2600; otherwise you get "HDMI ERROR" and "HDCP ERROR" BOTH MESSAGES DISPLAYED ON THE 2600 FRONT PANEL. So you wont see the GUI on your display device. You may? also need a source video signal into the 2700 to activate the 2700 to display a GUI (tested that but cant recall) but that is secondary because as I have said: you wont get a GUI display on your display advise .. you'll get nothing input to it from the 2700.
KEYPOINT: STAY AWAY FROM DVI INPUTTED DISPLAY DEVICES LIKE THE PLAGUE. Even DVI sourced devices (eg Cable Boxes) are frequently trouble with HDMI intermediates like receivers.
Hope u have better responses that me.
