Customer Reviews for Denon AVR-X6700H 11.2-Channel 8K AV Receiver with 3D Audio and Amazon Alexa Voice Control
Several months ago I noticed an issue with the HDMI operation. When there is a momentary break in the input signal, the output signal (i.e. Monitor 1/2) cuts out for approximately 7 seconds. This occurs as when the screen momentarily goes dark while starting or stopping a streaming program (Netflix, Prime, HBO, etc.). It also happens when the Blu-Ray player transitions from splash screen to a movie or back.
The issue is particularly annoying because after four seconds my monitor (2019 LG 4K OLED C1 TV) displays the error message "No Signal Present" prominently on the screen. In addition the AVR appears to degrade the video signal quality.
Recently, when I started an HBO movie on an Apple TV 4K, the sound track played for several minutes with no picture. When I restarted the program, my monitor displayed the error message “Unable to play this video: HDCP ERROR”. Rebooting the receiver corrected the problem.
I’ve noticed that on the transition from program material back to home screen, the component home screen (eg. Apple TV 4K) appears for a blink before the signal cuts out again for seven seconds.
When I bypass the AVR by inserting an HDMI coupler between the Device-in cable and the Monitor-out cable, these transitions are instantaneous - and the picture is distinctly richer - with no HDMI issues.
Denon claims there is an HDMI "handshake" within the Receiver. Maybe. However, I've been around computers long enough to know that sloppy coding and/or firmware bugs are enough to weigh down the best electronics.
After speaking with a service rep at Denon, I was supposed to receive a call back from a senior engineer. I’m still waiting for that call. The open ticket number with Denon for this issue is: 220204-0000664.
I’ll update this review as appropriate.
