Denon 3310CI timing out HTPC sound

Hope everyone is doing well.


When time permits, I wanted to see if anyone can shed some light on a problem I am having with the "Denon" screen popping up after say 10 minutes (when computer is inactive, i.e. not moving mouse) and timing out my HTPC sound? This does not seem to happen with video and sound like when watching a movie on netflix but if I am on itunes for instance it will just flash the black screen with "Denon" centered on my TV and HTPC sound and screen display disappear until the mouse is moved again.


Video card is ATI Radeon 5700 HD (1 gig card)

Running video and sound from HDMI on back of Radeon 5700 to HDP HDMI input on Denon 3310CI. In the setup menu for the receiver I have disabled the Denon screen saver and also tried disabling the text feature (was not sure what this was) but neither affected the black screen and "Denon" word from popping up in the center of my TV and cutting the audio and visual screen from my computer after appox 10 minutes of inactivity? I tried setting up the windows screen saver to see if this visual activity would keep things running but this also does not help.


Any advice would be greatly appreciated.


Thanks in advance
