Please do. I would love to hear your results.
I also have the issue with my Roku 4 as well.
The issue appears to be way worse whenever the component does native 4k for the UI resolution as well (such as the Roku and One S) and not as bad if the content from the component switches to 4K.
I also have a Fire Stick but it has been awhile since I hooked it up but I do not recall any issue with it.
It could be my imagination but the issue on the One does seem WAY worse when the One Guide / Live TV is enabled.
Also from what I can gather the issue may be a result of the HDMI 5 port on the Vizio only supporting 10Gbps bandwidth and not 18. This comes from other people though who seem to know a lot more about this stuff than myself. So I am wondering if some people have updated HDMI ports and some do not. I had the latest firmware installed, etc. And for me it is not even like it takes a little while to kick in, as soon as I switch the One to 4k UHD it happens almost immediately and keeps happening. With my Roku 4 it was only once about every 20 minutes so I lived with it thinking it was just the Roku 4.
Good Luck. I do no doubt hope you are one of the lucky ones! And I also am real curious to see if it works without the One Guide. There is no rhyme or reason to it but it really seems to happen when it is set up.
I used to have hdmi tv in and wonder if the overlay is 1080p. If so do you think the resolution keeps trying to switch from 1080p to 4k. Also does this only happen when the xbox resolution is set to 4k or does it happen on the 1080p setting? I do notice on my amazon fire box that when content is UHD it blacks out for a second and goes to 2160p rez. I could see a problem with a media device if this resolution switch the TV is implementing is constantly switching!
