I have had my Denon 3910 now for two days, and was wondering if any one has,adjusted the picture quality settings. Or do most people just use the factory set settings. My TV is a Hitachi 42" plasma (one of the old sorts so it does'nt have an HDMI input). The picture on the 3910 is very good although I can't say any better than the 2900 So will adjusting the picture quality settings make a good picture even better. I'd be greatful for any information on adjusting these settings. Thanks Mike.
