For example, my internet is soso at 15Mb. So when I stream 4k videos it normally takes about 30 seconds for it to ramp up. So I will initially get 1080p until it ramps up to 4k. But I noticed youtubes banner does not acknowledge this. If my video starts at 1080p the banner states HD, but after 15-30 seconds when the video gets to 4k that banner does not change. It stays at HD even though I am now getting 4k. I was able to test this without using the chromecast so I know I am not getting misled by its upscaling.
So while some people may have better internet speed they would likely get the 4k tag when starting the video, but if you are a little bit laggy it may start with the HD tag in the banner.
Yeah, funny you mention that... I think I have at least twice now.
Even with a connection like mine (100 Mbps that always passes speed test at 95+ or better) it can take a few seconds to spool up sometimes but most times right away. For that I am happy!
What he has been trying to do is compare apples and oranges. Here's the deal, on his first post he said "I have a fairly new Chromecast Ultra and a Vizio 4K TV with the HDMI 1.2 60Hz input that's on the Chromecast Ultra 4K TV compatibly list
"... which he later corrected to HDMI 2.2 which I pointed out that there is no such thing.
So since the Chromecast Ultra just hit the market recently, I guess he means his TV is "fairly new". In the tech world a model 1 or 2 years old can be out of date when it comes to some features. For example, with respect to the Vizio's it appears that the VP9 chipset wasn't included in the 2014 or 2015 models based on a quick glance at some old posts...

Biggest misconception back in the dark ages of TV (era 2014-2015) was that guys who were watching the same real 4K videos we are watching today were getting into big fights because they believed they were seeing 3840 x 2160 until the Stats for Nerds overlay screen came out which shot their theories down. A lot of delicious crow served on AVS Forum during those times!
First and foremast to receive 4K from the Chromecast Ultra, it needs to be hooked up to an HDMI 2.0 or HDMI 2.0a port for HDR. Four times now he has tried to provide that information but we still don't know. All we know at this point is it is hooked up to port 5 on a fairly new Vizio that provides 4K 60hz HDCP 2.2. Although one would think that would be HDMI 2.0 it sure would go a long way if guys just provided us with the Make, Model and Year of their TV so we can independently verify the specs.
Anyways, if the port is compatible and his internet speed is fast enough he should be able to stream YouTube and see the 4K badge or perhaps it is something else but that's what Google (manufacturer of the Chromecast Ultra and parent company of YouTube) gets paid the big bucks for!
Don't forget we all pay for YouTube with those commercials that interrupt our viewing of YouTube content!
STOP THE PRESS
Although he has been having us chase this issue on his Vizio regarding playing YouTube videos while displaying the Status for Nerds screen that is nothing but a red herring and has nothing to do with the Chromecast Ultra because, as I posted last night, and again above, his TV does not appear to support the VP9 codecs.
However, separating the oranges from the apples, here is a guy with a "fairly new" 2015 Vizio who is experiencing the same issue...

I've been dealing with Google support, but they haven't been a great deal of use so far.
Likely going to return and get a refund on the Ultra since all my other 4k devices work just fine on this TV (Xbox One S, PS4 Pro and Roku 4), but just wanted to see if anyone has gotten their Ultra to work on the 2015 Vizio M.
My advise would be to take it back
... but when has he ever listened to me.
, I know you, myself and a few others have gotten into a few words over the Chromecast Ultra but I think we have to accept the fact that the Chromecast Ultra has a few growing pains shall we say.
We are never going to figure out "the fixes". Google can't even figure them out so all of us in this thread need to sit back and let them do their job with all that ad revenue that pours into their multi-billion dollar empire.
If these are known issues, then those are Googles problem, not ours. Oh sure, I know you, me,
to name a few are keeners and most certainly available to provide a guiding hand but when a problem has already been acknowledged on Google's forums or on this thread we can only point that out and move on. Life's too short and summers coming!!!
It sure would go a long way if Google published a FAQ of known issues so we didn't have to do their job of in some cases have to take flack
from purchasers of their equipment!!!
Have a good one!
