I have a Roku Ultra connected to one of the three Denon 4K HDMI inputs. These support 4K/60Hz HDR10. However, the Roku fails on the detection and falls back to 1080p 60Hz HDR10 instead. If I take the Roku HDMI direct to my TV (Samsung UHD) the Roku now detects the display as desired.
I saw a similar problem posted about Apple TV and Denon recommended using 6Gbps HDMI cables which I'm already using (Monoprice Certified Premium, [email protected], HDR, 18Gbps, 36AWG, YUV, 4:4:4 - Ultra Slim Series).
Based on the above, my immediate thought is that it's an AVR problem, especially since this worked on my previous Yamaha (that had it's own problems with bluetooth and wireless and was replaced with this Denon).
UPDATE: Found the issue. Moved the AVR to TV HDMI input to "CBL/SAT" and now i get the full resolution. Apparently, the HDMI(ARC) input doesn't support it or is broken.
