Finally tested the Xbox One X. Two issues:
1. As I feared, setting the Xbox One X to display at 120Hz caused audio to fail. Since that device doesn't have any other multimedia outputs, like my GPU, I had to use a digital audio cable in order to hear anything. My concern is for games that support Dolby Atmos, as that is only carried over HDMI. Any ideas?
2. Also, changing the refresh rate to 120Hz only enabled 1080p resolution when connected via the Denon receiver (AVR-X4400H), just like with the PC. I had to bypass the AVR and connect the console directly to the TV's HDMI 4 (the only one left). Only then, 1440p @ 120Hz became an option.
This issue with the Denon not supporting 1440p @ 120Hz baffles me. As I mentioned before, HDMI 2.0b has more than enough bandwidth to support that resolution at that refresh rate, even with full chroma subsampling, so that shouldn't be a problem. I really hope that Denon and LG can figure this out soon and issue a fix, as there are a lot of consumers with that exact same setup (LG C9 and X4400H).

However, one other thing to try is make sure you have the Denon display overlay (ie. on-TV UI) turned off, as this may limit support for resolutions too.
Thanks for chiming in. 4K @ 120Hz really isn't supported, due to HDMI 2.0b bandwidth limitations. I was talking about 1440p @ 120Hz, which HDMI 2.0b can handle.

DVI (the output) can transmit audio, but it depends on the source, as this article explains
. And since DVI cables don't carry audio, you'd still have to use a DVI to HDMI cable or adapter.

Keep in mind that running at 120Hz over 60Hz also reduces motion distortion. And furthermore, decreases the input lag. Although we can't currently run 4k at 120Hz, it won't be too long before we can. I can't imagine gamers having any use for the 60Hz BFI.
Interesting, thanks for explaining. I wanted to test it out myself, but I can't seem to find the setting, would you mind helping me out? Is it available for all input modes? I definitely can't find it with input set to PC.

Not sure if I am keen on removing HUD elements just to save from image-retention. I will have to think about this aspect now before grabbing the C9. My E6 has already got alot of image retention from Windows 10 toolbars and gaming hud elements lol.
You can set Windows 10 to automatically hide the taskbar (only shows up on mouse hover) and run browsers in full screen mode, which also hiders their toolbars. That's what I've been doing since the B7. No burn-in whatsoever (image retention does occur sometimes, but it disappears after a while, so it's not a big deal).
