The first step is to install DOCKER. I first did this to get Pluto-Docker working. I sort of remember having to do something on my Windows machine to enable virtual machines.
Try going back in old forum posts on the Pluto/Docker system. If I remembered, I'd tell you, but all I remember is that it took several tries and forum members were very helpful.
Anybody getting the this match is available in 4K, But it looks like this device doesn't support 4K resolution. Visit fubo.tv/4k for a list of supported devices and browsers, on there CBS 4K stream?
Have you updated the docker?
I’m getting the CBS 4k stream with no issues
How do you update in portainer? It's been a minute since I have pulled down the latest image.
Stop the stack. Go into the stack editor and click on "Update the stack", followed by clicking on the "Re-pull and redeploy" slider.
Looking good for 4k

Have an updated docker container, but when watching either through Channels or even using VLC, the stream stops after 1 second. No error logs thrown up in Channels DVR, so not sure how to trouble shoot. Any suggestions?
Also, can confirm the FUBO App is showing the 4K stream on the same TV I'm trying to watch through Channels. Unfortunately no pause allowed. 
Are you using the HLS or MPEG-TS feed.
Mine is recording using the HLS feed.
I had this issue earlier. Switching to the HLS version fixed it. Set the "stream format" for the source in Channels DVR to HLS and change the source URL to the one that ends in playlist-hls.m3u.
Thank you for this. I have updated to v1.16 but still getting the Fubo still graphic.
I am getting the same thing when I tune to the channel on Fubo's website only place it's working is my Apple TV and iPhone & iPad. Only supported web browser's is Safari is what it says on there website. Every other channel on Fubo is working besides CBS 4K.
Correct. For live viewing of 4k that's all explained on the Fubo website https://support.fubo.tv/hc/en-us/articles/360011479911-Does-Fubo-offer-any-content-in-4K-HDR
You can record the 4k with Channels DVR.
Correct, I have read that article plus have gotten my docker container working but it still has that graphic up saying not supported browser when tuning into the channel on v1.16.
Using what channels client?
Apple TV, iPad, and iPhone.
How can I do this?, all of my fubo channels have the proper guide except CBS 4K
Are you using the HLS playlist?
Yes.

This is what the line looks like in mine
"1239200001": {"StationID": "152581", "name": "CBS 4K"},
Make sure the web page where the playlist links are found says it’s 1.16
