Solving playback issues

[bradamant]

Hi folks, I posted about some problems a while back when I got a new Roku Ultra and attached it to my old TV. Got that fixed, but now I've gotten a new TV (2022 Samsung The Frame) and plugged the Roku into it using a Monoprice 8k certified cable. All of these elements seem like they should allow for 4k playback but the error message I get... well it's so confusing that I don't actually know what I'm getting! The error refers me to a help page that doesn't cover this scenario. But it seems like I'm not getting 4k, or maybe I'm not getting it at the right frame rate or I can't get HDR picture quality at 4k? I'd appreciate if anyone could shed any light on what is going on here and what should be going on too!

On Samsung TVs, you need to go into the HDMI settings and enable "UHD Color" on the port your Roku is using.

If you are using an AVR and your Roku is connected directly to it, you would enable that setting on the port that the AVR is connected to. Also, your AVR would need to support 4K/60, which isn't a certainty. If your AVR does support 4K, make sure you have video passthrough enabled so it isn't altering the video feed.

Thank you so much! You saved me a lot of research and wasting money on extra cables.

It took some digging in the Samsung menus to execute this so let me leave breadcrumbs for anyone else encountering this.

(Samsung not Roku) Menu > Settings > All Settings > Connection > External Device Manager > Input Signal Plus

Then go to the input you want to change and click it. It didn't give me any choices but put up some message about having switched to HDR? Sorry, I didn't write that part down and don't want to risk switching it back.

I tried the Roku automatic detection thing again and now it says 4k!

@bradamant-

Thanks for reporting back and sharing your findings.  I wish more people did that.

Thank you so much for posting this specific information - saved me a ton of time and hassle.  The information on the Roku site is outdated based on the new Samsung menu options.  Again, really really appreciate this!

Thank you! On LG, this is Settings --> All Settings --> General --> Devices --> HDMI Settings --> HDMI Deep Color.
