Denon AVR-X3600H and Firestick 4K issue.
Sorry if this is in the wrong place. I've searched and am struggling to see any similar threads. Basically I get no picture output from the FireStick 4K if I have the HDMI ports on the Denon Enhanced mode. I also have a Humax and UHD Blue-Ray connected and they work fine when enhanced mode if selected. The FireStick works with the HDMI ports in standard mode fine, I get UHD / HDR and Dolby vision passed to the screen via the Amp (but YouTube won't playback in 4k
). I have the 4k Firestick plugged into the media player HDMI port at the back of the Amp (close to the output as suggested by Denon), I have disabled the video conversion option. no difference.
The resolution on the Stick is set to auto. colour space up to 12bit. I have manually set the resolution to 4K and 1080 but the results are the same. Match original frame rate - set to ON. Colour format - Automatic. Dynamic range settings - Adaptive.
Any suggestions would be great.
You are using a rear port on the Denon - which is good because the front HDMI inputs on some (maybe all) Denon AVRs are not full-bandwidth capable. You should always use an HDMI port on the rear which support the full 18 gigabits per second bandwidth specification.
Your HDMI cables may not allow you to reliably pass 4K UHD HDR content at 60 Hz. 12 bit HDR is required for Dolby Vision content.
What Display Device are you using?
What HDMI cable lengths are you using?
Are the cables HDMI Premium certified?
On the Fire TV stick, don't force the resolution to 4K - leave it at Auto.
NetFlix *always* uses 60 Hz 4K. You need 12 bit HDR for DolbyVision. The NetFlix App does *not* support the 'Match Original Frame rate' option provided by the the Fire TV stick. NetFlix need to update their App to support this, and they stubbornly refuse to do so.
60 Hz, 4K HDR requires far, far more bandwidth than even a 4K Blu-ray with Dolby Vision which only uses 24 Hz. The only current Blu-ray exception is 'Billy Linn's Long Halftime Walk' and the up and coming release of 'Gemini Man' which are 60 Hz titles.
Amazon Prime content *does* support the match original frame rate option. Try watching 'Jack Ryan' or an episode of Season 4 of 'The Expanse' in 4K - both of these use HDR, but they only require 24 Hz, so they may work OK. Only Season 4 of the Expanse is in HDR, the previous seasons are available in 4K, but without HDR.
I'm not familiar with 'Standard' and 'Enhanced' modes - my Denon X6200W doesn't have this feature. But it sounds to me like Standard limits the bandwidth to 10 gigabits per second, whereas Enhanced enables the full-fat 18 gigabits per second. It's bad terminology as the UHD standard specifies 18 gigabits per second, not 10. They should call 'Standard Mode', 'Reduced Mode' or 'Limited Mode' but whatever...
Some Epson projectors are limited to 10 gigabits per second (as are the front HDMI ports of the Denon).
4K UHD at 30 Hz with HDR fits within the 10 gigabit limitation, but 60 Hz won't fit.
Hope this helps.

James.
