I posted this on reddit/r/hometheater and one of the people there suggested getting in touch with you guys, specifically a problem in the first paragraph.
I bought this after consulting various internet forums and reddits a few months ago
. It has worked wonderfully, except for the fact that the audio will not go up or down after power on unless you switch it off and on quickly a couple times.
It has firmware version 2400-4140-6075 currently on it, and checking for firmware updates, it says it's on the latest available.
Will it support HDR, HDMI 2.0a, and BT.2020 should I buy a 4k tv in the next couple of years? Has anyone tested this model with a 4k tv before? or did I buy it at the wrong time, seeing as new models came out?
The person suggested I contact JDsmoothie regarding the underlined issue.
(S)he said this:
"I wouldn't think so (If my settings file would carry over this bug) and if you've already done 2 factory resets already I doubt it will help. I would call Denon support and get a ticket started on it. They will have you try several things first (like a factory reset) that you've already done but it sounds like there's something wrong with the receiver. If you can get past the first level of CS people maybe you could get a tech on the line or get a call back from one who might have more insight but I wouldn't just put up with it doing that. Somethings up.
