I am a "previous" owner of a 4311, as I have returned it due to locking-up of the unit. I would ask if anyone else has had these issues?
The set-up is with a HTPC using an ATI 5670 card, and only Cable TV on the other HDMI input. The 4311 is set to "control" HDMI stand-by, and input set to "last". The PC has "exclusivity mode" checked in the advanced properties.
If I have the HTPC displayed through the 4311 on the TV, and then shut-down the 4311, the unit takes 5 seconds and then returns with TV displayed. I then go to turn on 4311 and "Denon" screen comes up on HTPC input(BD in this case). The first workaround was to hit the "Quick Select BD" button, as the regular "BD" input button did nothing. I basically needed to return to a different input "Cable,DVD,Game,etc.) in order to get back to a functioning HTPC input. While this worked, it could not be understood by wife and kids.
So next I set the stand-by input to BD(HTPC) as default. This helped if I shut-down 4311 in BD mode, but if I shut it down in USB/NET mode, and turn 4311 back on, the TV goes black but BD is displayed as input on TV. This also locks up the receiver consistently. I need to unplug to reset. It is unresponsive to remote or front panel commands. And yes, I reset network and uProcessor many times...
I really liked this receiver, and would like to buy again (I did buy from EE for the 1299 and they were awesome at taking it back and return label shipping),but it seems incompatible with my HTPC for some reason. I spoke with Denon and they blamed Microsoft for not maintaining EDID properly. It does seem like a "handshake" issue. I wish HDMI was dumbed down a bit to aviod this crap. The CEC is turned off on the TV also, and I do not have any problems going direct into the Samsung TV
