YouTube App isn't running in 4k


Recommended Posts

I just purchased the LG UHD 43UP76 advertised as real 4k however the YouTube App is running at 1080p.  Which means 4k content is downsampled to 1080p then reupsampled to fit the 4k pixel grid and the image quality is awful.

i assume WebOS runs at 1080p and simply upscales to 4k on low end 4k TVs, this same with high end TVs??

It might just be the app.  Make sure you specify you want 4k in the app (I THINK you can do that).  I seem to recall youtube doing something similar to me and I just put it to 4k instead of "auto".  Then the Nerd Stats actually showed that it was doing 4k. It might also be that your network connection doesn't have enough throughput.  I've read that on many of the TVs, the network card is very slow.  It was on my TV.  I switched it to use the "5g" wifi connection and it didn't have any problems.

Good luck.

I have 100mbps wired Internet, it can handle 4k . The only to way get 4k content is through an HDMI device not through the TV apps

I'm not quite following you. The youtube app definitely can specify and deliver 4k. Have you looked at the nerd stats? At least with my tv and youtube app.

On the Nerd Stats, the viewport must match the current video resolution.  If the viewport is 1920x1080*2.00, the 4k video is downsampled to that resolution.  

In fact if you play a YouTube video at 240p, 480p, 720p, 1440p the viewport will always be at 1920x1080, the screen resolution of the software. 

For example if i have a 4K PC monitor and i set the resolution to 1080p in the display option and play a 4k YouTube video, the stats will say "Viewport 1920x1080 ... Current / Optimal Res 3840x2160.

I see what you are saying.  I was almost POSITIVE that at one point I saw 4k at both the viewport and the resolution, but when I checked tonight, yep, 1080*2.  It DOES LOOK better than 1080 though.  I'll experiment with it more myself.  Sorry for not getting what you were saying initially.

Ok, I did a little more testing with my LG OLE65BA7 TV.  I took pictures of the screen.  Here is what I took:

1. Xbox Youtube app

2. Roku Youtube app

3. TV Youtube app

4. Netflix network test

 

The end result is, I don't know if I trust the stats for nerds to really say what is going on.  Summary:

 

Even though Netflix says I am getting 221 Mbps on network test (my ISP is supposed to be 200Mbps so I believe that number) and Xbox Youtube says it is getting 153Mbps connection speed while playing the video, Roku says it is only getting 45Mbps.  And TV app says it is getting 64Mbps.  And Xbox says ZERO network activity?

Xbox is only one that says viewport and display are 4k

Maybe that drop in speed is because it is doing the upscaling?  And that takes away from overall throughput?  But, again, it LOOKS great.

So I think I was remembering the 4k viewport and display from the Xbox and the others said they were doing 4k so I assumed it was.

 

Don't know if any of this is any help, or it is just confirming what you were complaining about in the first post.

 

p.s.

   After posting, I finally noticed the paper clip icon for adding "other media" and I've included them here.  Don't know if the upload process changes resolution of attachments.

After doing a few more tests, I see that it looks like the network activity goes in spurts.  I suppose it downloads some stuff into the buffer and then doesn't do anything else while the video is being played from the buffer.

I looked up close at the screen (about a foot away) at a girl fishing in a boat in Norway as a drone passed over head.  Although I didn't have a side by side comparison, they looked the same to me whether or not it was TV Youtube app or Xbox Youtube app.  And this time, I also was getting about 115Mbps while running the TV app.  Not sure why the variability.  So many possible reasons.  But again, visually, it looks fine to me as far as I can tell without having some sort of standard test to run.

Hey thanks for the super helpful reply. I'm not sure how I missed that thread. I haven't quite mastered the search function on here. I think I'll pass with him this time around. If i want any further guideline we will contact you here.

      Hi, I'm curious if anyone else is seeing this annoying new behaviour.
      I have my SKY Q box on HDMI1 and have become accustomed to switching back from Netflix (or any other app for that matter) by having HDMI1 assigned to button "1" using the Quick Access feature.  In the last week though, this feature has stopped working properly. If I am in Netflix and I press the "1" button, nothing happens (as expected). If instead I hold down the "1" button to switch to SKY I get a pop up that says this: "Do you want to add Netflix to [Quick Access 1]?".   If I then hold down the "0" button, the 3x3 grid "EDIT QUICK ACCESS" pop-up appears and I can clearly see my SKY Q/HDMI 1 in the top left grid position (button "1")!!!
      If I then switch via the Home button to HDMI1 and remove HDMI1 from Quick Access (via the  EDIT QUICK ACCESS pop up), I can then re-add it by holding down 1 or from within the pop-up. Now, if I go into Netflix and then hold down 1, my TV does (correctly) switch to HDMI1. Hurrah! If however I turn my TV off and back on, then go to Netflix, then hold down "1", I am back to square one with the question "Do you want to add Netwflix to [Quick Access 1]?"......Grrrr!!!
      I have tried switching the TV off at the wall, leaving for 10 seconds and repowering, which doesn't fix the problem (I don't believe WebOS reboots when you do this). LG appear to have made it a practical impossibility to reboot WebOS via anything other than a factory reset which I don't really want to do as it'll take me too long to get all my settings back to where I have them now. Some blogs suggest that the "User Licence agreement" setting can be changed which forces a reset from within the General tab but I don't see this on my TV (guessing that WebOS interface has changed).
      Anyone have any ideas? 
      Rob.

      Subtitles aren't appearing for certain shows(eg. Big Bang theory).NO option to change audio language,video quality. Certain shows are like watching snapshots at 10s interval(check Homeland). Cricket matches are having slow frames per second although i have good bandwidth and fps on my tv(LG UJ652T).  NO VIP option also.

      Hi,
      the WebOS specs stated that HLS is supported but didn't mention CMAF (or fragmented MP4) support.
      Therefore my question if CMAF(HLS)-Encodings are supported?
      Regards
      Riva
