Intel HD4600 (4790k)
Windows 10 pro x64 10.0.10586
Driver from WU 20.19.15.4331
Denon AVR-591 (hdmi 1.4)
Dell 2709w
The connection goes like this
PC > HDMI > Receiver > HDMI > Monitor
My question is:
Is it possible to pass-through (bitstream) HD audio like DTS-HD and TrueHD at higher resolutions that 1080p50 or i'm missing something ? it's a driver or bandwith limitation problem?
It seems odd that i can pass-through DTS-HD and Dolby TrueHD at 1080p50 but not at 1080p60, tried a lot of drivers, but always had the same results.
Furthermore, the monitor its 1920x1200 but at that resolution i can't pass-through the HD audio modes
To by pass this problem, i have connected:
PC > HDMI > Receiver > HDMI > Monitor
PC > DVI > Monitor
Then configured DVI as Main input at 1200p60 and HDMI as Secondary at 1080p50, this way i can bitstream HD audio and use the full resolution of my monitor.
Note that I can bitstream DTS and Dolby digital without problems at any resolution mode, and always have the HDCP marked as compatible.

Hello ivanu, thank you for responding, that driver is older and i've already tested it and unfortunately doesn't fix it.

I'm sorry the driver did not help you, in this case I would recommend waiting for someone else to post an answer here related with this topic. From my end I will try to do some more research and if I find something that can help you I will post it here.
Thanks,
Ivan
