As you guys know I have been testing between a Denon AVR-X2200W and an Onkyo 747. One of them is slated to replace me 5 year old Denon 2311CI. My TV, Speakers, Cabling, Sub, and so on have not changed in this environment. So yesterday evening I discovered a major problem!! After hours of testing with both the 747 and the 2200W and issue came up with dimming. I saw it one before last week when my son was playing NHL 15 where the screen would just randomly dim 50% and stay that way. I could switch between sources to get to come out but it would only last temporarily. The other sources would not do this...just the xbox one and the xbox one would only do it with the 2200W...not with the 747 or the 2311CI. So this is strange!!! For example, I was playing the matrix revolution last night and when a scene switches to a dark area the screen dims 50% and stays there. If I unplug and replug in the HDMI while it is still going it will go back to full but will not stay. Sometimes for 1 minute sometimes for 3-4 but wham, if would go dim again. So I hooked up the 747 again as well as the 2311...doesnt do this with either of them, which rules out the xbox one as the problem! I can duplicate the issues every time and it doesnt just happen with the matrix, when my sons started a game of NHL 15 it did it as well. It did not do it with any of the star wars, Avengers, Battleship, Star Trek and a number of others. Once again, I can get the dimming issues to go away If I switch from the blu-ray source to the CBL/SAT it is back to normal but doesnt stay. CBL/SAT source (which is my comcast DVR) has never exhibited this! I believe to either have a bad unit or denon has a problem on their hands here! Once again I cannot tell you how much I like the sound better on the Denon and the video quality was better as well than the 747. But this is a major problem. Some background and why I believe this is pointing to the new denon is this. I have had the Xbox One hooked up to my old Denon 2311Ci for over a year, it has seen 100s of Blu-ray movies and a number of games with not a single issue. All the cabling is the same (Xbox came with its own 4k xbox ready one cable) so It is not a cabling issues not to mention it does NOT exhibit this with the 747 either. My trouble shooting has been power cycling on the xbox one, power cycle on the denon. I have tried different HDMIs on the X2200W as well. Still the same dimming issues happens. I have scoured google for this issue with no avail. Many years ago there was some mention with the Xbox 360 but the issue was not the same. It only does this with the xbox one and 2200W combination. I might grab another blu-ray player to see if that is the case. Either I have a defective x2200w or this is a design issue. Either way it really breaks my heart!! Its a sad day! I am within the 30 day period with denon so it might go back!! It sad because I love the sound on this unit. It has far exceeded the 747 and the 2311CI!! I am extremely impressed. I do not know if this is related to the video processing on the denon or not. I have went into the setting and disabled a number of things with once again, no avail! I dont know what else to troubleshoot for I dont believe I have left any stone unturned!
