Denon AVR-X1600H won't pass thru 4k UHD 60fps (1 Viewer)

[allnight]

I have a new Denon AVR-X1600H connected to an LG OLED77CX screen. I also have a new Roku Ultra 4800.

When the Roku tries to detect the monitor, it decides that 4k UHD 60Hz doesn't work.

If either of the HDMI cables connect the Roku directly to the TV, it says 60Hz works great. If I connect the Roku to the CBL/SAT input on the X1600, the Roku decides that 60Hz doesn't work. The cables are both new; one came with the Roku, the other claims to be good for 8k video. However, since both work when directly connected, I'm confident it's not the cables.

I haven't been able to find anything that would enable/disable it.

Does anybody have any idea what's up?

Well, after spending even more time digging around, I found the article below. Based on that, I went digging through the settings on the Denon, and in Video->4K Signal Format I changed from Standard to Enhanced.
