I also have the same problem as the original poster. Buffering on 4k videos in both YouTube TV app and YT. Every 2 seconds. Downgrading to 1440 alows playback. Occurs over wifi as well as wired connection. Speeds are 48mbps to 100mbps. I'd be happy to provide the usual menu of detailed data as my predecessors, but how about just providing an answer/solution to the problems already laid out in great detail. I have 4 tcl Roku TV's. I'd like to watch TV in 4k. Waiting for a answer or solution.
Same problem with my TCL Roku TV. Only youtube 4K 60fps content gets constant buffering. Some 4K 30 fps is ok but most 4K content at any fps buffers. Anything lower resolution does not buffer. I am on a 1Gbps fiber connection and wired via Ethernet to the TV. Playing 4K youtube on PC or other devices is fine.
If you haven't already, can you please provide us the following information: -Roku device model, serial number, device ID, and software OS/version (these can all be found in Settings > System > About) -does this issue occur on a specific channel? if so, what channel and what version/build is the channel (this can be found be selecting the channel on the Home screen and pressing the * button) -tracker ID when this issue occurs (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times) -steps to reproduce the issue you are seeing
Once we have this information, we will be able to pass it along to the appropriate Roku team to investigate further.
As others have mentioned earlier, this issue is specific to Youtube app. Youtube streaming seems to have limited bandwidth which is causing the constant buffering. The original poster has indicated that bandwidth is limited to 10mbps in Youtube Roku app which is not enough for 4K streaming.
Yep, and I don't like being stonewalled by this company. These TVs were sold pre-loaded with the YouTube app in a partnership between Roku and TCL and advertised to support 4K streaming playback. This feature was effectively removed with the last software update.
In my opinion, Roku has had ample time to address this issue and it's becoming clear that they have no intent whatsoever to address the issue.
Roku needs to have a supervisor reach out and explain what is being done to address the deficiency and in what timeframe we can expect the issue to be rectified. I'm expecting a response within 72 hours.
