Playback Issues - Audio/Video & Power

[efny]

I have a Vizio 4k 60Hz HDR TV that's connected to the Roku via a Marantz SR5013 receiver. I can direct drive this content via a number of other sources including Bluray player or PC. It passes 4k/60/HDR test on Roku, and that's what it auto-detects as well. However, immediately after switching to 4k/60/HDR I still have sound, but no video input. I can hear the little clicks moving the cursor, and if I remember the order of keypresses, can actually switch to 4k/60 without HDR to get my video back. There is no problem if I drive the TV directly from Roku, but there is clearly a Roku-specific video problem that occurs with HDR when using the receiver, since EVERY other source has no problem with this. I have updated the receiver  and Roku firmware, and the receiver is definitely HDCP 2.2 compatible. I've tried playing with HDR subsampling rates, etc... This is quite unsatisfying since this limits digital streaming to my home theater, which was the whole point I got the Roku. I'm pretty close to abandoning the Roku for another device (Shield, AppleTV, etc) if I cannot get this issue resolved.

I have identical issue with similar setup: Roku 4 -> Yamaha Receiver -> Samsung TV.  Other devices (Blueray DVD and TiVo work fine through the receiver.  I've changed cables, outputs, swapped receivers and swapped Roku 4 for Roku 3.  The issue still repeats.  I've been through resets, resolution, etc, etc. 

This has been a stable set-up for year... the issue only started in Apr 2020 -- has there been any software updates this month?

This is simple - if this isn't going to be fixed by software version 9.3 (which has been released but hasn't come to my Roku), I'm going to buy an Nvidia shield. Not only does it play Google Play videos at 4k, but it can then be a gaming hub. Wouldn't it suck for Roku to lose a client that bought multiple devices over several generations because of this...

The Roku 4 does not support HDR, so can't be the same issue. So what exactly is your issue?

Actually I believe that the Shield has issues with HDR in Google Play as well. It does fine with Amazon Prime, Vudu or local content. And if you care about YouTube HDR, the Shield does not support and never will until YouTube switches from the VP9 profile 2 to AV1 video codec.

What do you mean Roku doesn't support HDR?

For me the problem is that any time there's a power cycle, or the Roku just decides to "auto" select source quality (which it tests as 4k/60hz/hdr), I lose picture and have to blindly count clicks to use the remote to switch to 4k/60 in the menu. I literally have a printout of "home->two clicks up->click left, etc" sitting on my mantle because this happens so often. It's infuriating.

Whoops, typo. The Roku 4 does not support HDR. I'll edit that response so it isn't misleading.

I'm running my Roku Ultra 4630x to my two-year-old Vizio.   It's confusing as **bleep** because apparently only HDMI-1 (ARC) is compatible with HDR.   However,  I can place my HDMI cable in the second slot over and ROKU auto-detects that it is 4K HDR 60Mhz.   If I run a 4K HDR video in PLEX or Emby, it works until I exit the video, then I get a scrambled blank screen.  The only way to fix it was to unplug the Roku, then plug in back in.  This happens with YouTube 4K HDR videos as well.   This only happens with HDR videos.

HOWEVER...Just for kicks,  I set the the Video Display to 4K HDR 30Mhz instead of 60 Mhz.  This seems to have fixed the problem.  I'm going to live with this until I can get me a new display.

@tarinr I'm assuming you made a typo, as the 4630 is the Premiere, not the Ultra.

Most 4K TVs have a setting on each HDMI port to enable full bandwidth. Samsung calls it UHD Color, and other brands have different names. But in every case I've seen you have to enable that setting on each port separately. One possible thing to look at.

I found that the HDR Roku players are quite sensitive to the HDMI cable quality. The cable I used for my Roku 4 (4K but no HDR) would not even link up with my first Ultra. You might try a different cable. Also check for any dust/crud within the port or cable connections.

That wasn't a typo....that was old age.

You are correct it is the Premiere.   My ports can have UHD Color enabled and that seems to work.  The picture looks great,  but it craps out upon exiting the video.  It has to have something to do with the refresh rate not syncing at 60Hz.   Because it doesn't do it when I manually choose the 30Hz setting.  I probably need to unplug EVERYTHING and make sure I have a good solid handshake and connection.
