Yeah. I am familiar with that thread. I read about 500 of the 2500 posts. I know there are a lot of other people with that problem but I could not find a solution. I did a google of the 2910 and the old Audioholics review came up. I was hoping to find a clue in there but you guys did not test it with an HDMI connection. Probably would of uncovered it then. That gave me the idea to post to find a solution.
I checked my Denon online upgrade status a couple of years ago at the Denon website and it said there are no updates for my model and serial number. I assume then I have the latest firmware upgrade. I tried again today, Saturday and the Denon website now does not recognize my serial number for a 2910-black. I am guessing the server is down over the weekend. Will try on Monday.
I am not sure which version of firmware I have other than that. How can I find out?
