I just upgraded from a Harman Kardon AVR-247 to a Denon AVR-991...I have one issue - the picture quality is lower with the Denon than the HK. I've searched the forum, the net and Denon's site for an answer.
I changed the DNR to reduce the picture noise but didn't notice much of an improvement.
Here's what I have:
5.1 surround system - Cambridge Soundworks speakers (FL, C, FR, SL, SR, Sub),
Toshiba LCD television (three to four years old), Comcast Xfinity cable/DVR, PS3, Wii.
Picture when watching a BluRay disc is also lower than it was with the HK.
Cable box, Wii and PS3 connect to the Denon->television
All connections are via HDMI.
I'd appreciate some pointers to correct the issue. I have spent a LOT of time reading the owner's manual and found nothing that will solve the problem.
Thanks in advance!
