Can't get 4K 10-bit to work

Hi forum--

I have a brand new:

Onkyo TX NR-777
Sony X900F

And a Roku 4.

I have set the X900F HDMI input 3 to "Enhanced Format". When I go to secret menu HHHHHDLUUU, it says:

MFG: ONK PRDCT: 4464 SN: 0 NAME: AV Receiver
Supports: Yes to every single thing

But when I try to select 4K,10bit,60Hz, I do not get a screen. Just whole screen blue until the Roku reverts back to 4K,60Hz.

Many people say you can change the Roku to 4:2:0 in this secret menu, but I do not have that option. All I see is "Enable HDMI fast suspend" and "Disable automatic Recovery".

Do I need to get a Roku Ultra for HDR? I have seen A LOT of complaints about Roku Ultra and HDMI issues. Should I get an Apple TV instead?

Thanks!

Re: Can't get 4K 10-bit to work

First, yes you need a different Roku for HDR. The Roku 4 is 4K, but not HDR. As far as the 4:2:0 setting, it's no longer hidden in a secret menu, but is under System/Advanced System Settings. I don't have any experience with Onkyo, buy my Yamaha AVRs have an advanced menu that has a setting that has to be correct for full 4K/60 Hz. Yamaha labels it "Mode" and Mode 1 is necessary for full 4K/60 passthrough. 
.
Personally, the biggest issue my Ultra ever had was when I replaced my 4 and I couldn't get a good (reliable) 4K resolution setting. For me the issue was my HDMI cables weren't sufficient for 4K/60. They have to be certified for 18 Gbps data speed. I bought a couple of Amazon Basics cables and haven't had an issue since. Every once in a while I see the HDCP error message, but it always disappears in less than a second. Not enough time to even read the warning.  Smiley Very Happy

Re: Can't get 4K 10-bit to work

Thanks for the answers guys!

I got my Roku Ultra (now I have a 3, 4 & Ultra). I also got 2 18Gbps HDMI cables (Roku->AVR->TV).

So now HDR is working. 4K,60Hz,HDR. Next complaint is that captions are relatively dim when watching HDR (Altered Carbon for example). New thread...

Thanks again!
