When I first got my 4k TV, the videos would always play on the highest available resolution on the youtube app. After some time the app started to present low resolutions. To fix that:

 

Clear your cookies on the app's settings. It solved here, playing again the videos on the highest available resolution .

 

If you're logged, you will have to log in again after that.

Lg tv WebOS,Is their a way to make youtube videos default to HD if available ...

If the video is available in 720, 1080, or higher, it will automatically display in HD so long as you have ample bandwidth and you subscribe to an internet speed sufficient enough to stream these resolutions. You can check your streams by going to "Settings" >> "Display Video Info." This should show you all the info you need to know in order to determine what the problem is.

Hi,

 

What do you mean by clearing cookies? Clearing cookies on a pc or on tv?

Youtube's app for tv has settings menu. There you can find a "clear cookies" option.

 Thanks so much for the hint. I did it but no success. All videos play default at 1080p. When I bought my TV I watched some 4k videos by youtube app but not anymore. I don't know why. I think it depends on the video itself. I mean fps, codec and other factors.

50Mbits = 6.25MBytes/sec, @720, 1280*720*3(yuv 4:4:4 worst case) = 2.63MB/s, @1080, 1920*1080*3 = 5.93 MB/s (very close and exclude payload, header, etc.), question the subscription 50Mbps is not always stable and fluctuate. I think maybe that are the reasons why it didn't stream at higher resolution. My guess, hope is useful.

I checked out the video you referenced above; "4K Video ❤ Beauty of Nature"

First thing's first, that video is RIDICULOUSLY beautiful! I stood there dumbfounded. It was jaw-dropping!

 

Problem #1: On a more technical note, this video has issues being loaded into the buffer. Something is definitely wrong utilizing DASH* on this video. The first few times it wouldn't even play. It would just show a frozen image at precisely 45 seconds in. I had to tickle DASH into working properly again by scanning backwards to 0:00. This forced a buffer purge, and then video reloaded, correctly this time.

Then came the magic, albeit lasting only approximately 1 minute, 30 seconds, it was still absolutely breathtaking.  

 

Problem #2: I am noticing inconsistencies with my 4K viewing experience overall. Most play, but some do not.

Sometimes it is a framerate vs bitrate issue; noting that although the TV specs can handle VP9, there are "flavors" of VP9 that the TV cannot and will not handle, but will always attempt to decode (and fail.) I have documented some of these videos for study. The only consistency I do find is the following: If the video doesn't play for any reason other than a DASH issue, that video will never play, period. I can always count on my documented list to NEVER work. This is good because I (we) can recreate the issue and gently compel Youtube and/or LG to address it accordingly.

 

Problem #3: Limited Control. I understand that LG wants everyone to have the same positive and consistent viewing experience on all of their 4K models, doing so requires some restriction on control, however, lacking this control prevents the user from making some crucial adjustments that may allow for a better viewing and listening experience. With that said, LG/Youtube should add a true "Advanced Settings" feature that allows for control over things such as DASH, Aspect Ratio, Audio and Codec tweaks. They should also allow for more passive intelligent diagnostic information to be available to the user on the fly. In easier terms, I'd like to see a diagnostics overlay that measure all relevant metrics and then can diagnose the problem and give you an on screen message.

 

Here are some imaginary examples that would benefit everyone:

 

1."Video has been reduced to standard HD due to insufficient bandwidth. Your Speed: 12Mbps (4K/UHD 25Mbps) Video will return to 4K/UHD automatically once your speed reaches 25Mbps or greater"

2. "The 4K video you are trying to play was not optimized for your 4K set and may not play properly, if you still wish to play, click 'Continue' or click 'Play in HD' and your video will be presented in standard HD. Reason: bitrate exceeds xxxbps"

3. "The 4k video you are trying to play exceeds maximum buffer size, if you still wish to play, click 'Continue' to disable DASH for this video playback or click 'Play in HD' and your video will be presented in standard HD. Reason: Buffer size exceeds maximum" "*Note by temporarily disabling DASH, your video may experience stuttering and/or freezing, but will play in 4K"

*Dynamic Adaptive Streaming over HTTP, What Youtube uses as a video preloading system.

 

My final thoughts on all of this are clear: I see now that there are some videos are fine and some that are not. Apart from bandwidth issues, I think these TVs at the very least need to tell us whether or not the video we are about to play on our TV sets will actually play and if so, whether it will be in 4K or plain HD (and why if at all possible.)

 

Does anyone share the same thoughts?

Happy Holidays Everyone!

 

on my UB850 after cleaning cookies, log in and pairing chrome all the videos is still only in 720p

It will never play 4K though. You can change your Youtube settings from the app to display the quality and other paremeters during video playback, this might help you determine what quality youtube is displaying.

Yes, I mentioned that in my post; "Display Video Info" will display the video resolution you are viewing and the codec.

You stated that it will never play 4K. I can testify that it does, in fact, play 4k YouTube videos.

I apologize for the angle; I took a picture of my TV screen with my mobile phone.

I truly regret that you are having trouble, but perhaps I can help...

In a different post I mentioned an LG glitch which prevented me from getting UHD on the Amazon app.

It was the same reason I didn't get UHD/4k from Youtube as well, in the beginning.

Here is what I did to remedy the issue:

 

To fix: 

1. Make sure you are on the latest WebOS firmware.

2. Uninstall the affected premium app(s.)

3. ReInstall the affected premium app(s.)

4. Re-Launch your affected app(s.)

 

If you are still having the issue and are 100% certain that insufficient bandwidth or speed is the cause, then I can offer you no further suggestions for Amazon.

One thing to note for Youtube 4k videos...the bit rates for VP9 seem to vary drastically. 

 

You may discover some video content labeled 4K that was not optimally* encoded in vp9. 

If this is the case you will either: 

A. Get the 1080p or 720p version of the video, or

B. Get severe stuttering and freezing on the 4K version.

 

It is sad, really.. some of those ones I encountered that had the stuttering and freezing were quite beautiful.  :(

*That results in a framerate and resolution the LG will handle well.

      LG’s New 32HR734S 4K Surgical Monitor With Mini LED Technology Delivers Outstanding Image Quality
      By News Reporter
      Designed for the Healthcare Sector, Company’s Latest Medical Monitor
      Provides Impressive Imaging and Convenient Features

      SEOUL, Oct. 9, 2024 — LG Electronics (LG) is launching its new 31.5-inch surgical monitor (model 32HR734S) featuring advanced Mini LED display technology. Designed to provide color video displays of images from surgical endoscopes, laparoscopic camera systems and other compatible medical imaging systems, LG’s monitor has received 510(k) clearance from the U.S. FDA, indicating it can now be sold in the U.S. The 32HR734S’s Mini LED technology enables precise brightness control and provides a wide color range, optimizing image clarity and color, making it an ideal choice for a variety of surgical applications, including laparoscopy and endoscopy.
      The 32HR734S features a 31.5-inch, 4K resolution (3,840 x 2,160) Mini-LED display leveraging thousands of tiny LED diodes as the Back Light Unit (BLU). Delivering 2,000 cd/m² peak brightness and a dynamic contrast ratio of 1,000,000:1, LG’s medical monitor leverages 1,536 local dimming zones to produce clear, detailed images and enhanced visual contrast. The display also provides excellent color consistency across the screen and boasts 98 percent coverage of the DCI-P3 color space.
      In addition to its impressive visual performance, the 32HR734S delivers the durability and reliability necessary for surgical settings. Employing Optical Bonding technology, along with Anti-Glare, Anti-Reflection and Anti-Fingerprint coatings on its front, LG’s 32HR734S 4K surgical monitor ensures optimal visibility even in brightly lit operating rooms. What’s more, the front and rear of the product (IP45- and IP32-rated, respectively) offer excellent resistance to water and dust, preventing fluids or particles from disrupting monitor operation during surgeries.
      The 32HR734S is also the first LG surgical monitor to incorporate the innovative Clone Screen feature. Clone Screen allows users to duplicate the image being displayed on the 32HR734S on a second monitor (connected via HDMI), significantly enhancing operational efficiency and communication within the surgical environment, especially in situations where multiple medical professionals need to view the same image.
      For added versatility, the display’s Mirror Mode makes it possible to flip the on-screen image horizontally, while Rotation Mode can rotate the image 180 degrees to match the orientation of the surgical camera. The 32HR734S also provides Picture-in-Picture (PIP) and Picture-by-Picture (PBP) functionality, the latter allowing the display of up to four different image sources simultaneously. This enables medical staff to view a combination of inputs or images, such as laparoscopic and fluoroscopic images, while monitoring the patient’s vital signs at the same time.
      “Featuring advanced Mini LED technology, the 32HR734S delivers the excellent picture quality and convenient functionality needed in surgical settings,” said YS Lee, vice president and head of the IT business unit of LG Business Solutions Company. “We believe our new model will significantly boost efficiency for medical professionals performing and assisting with surgeries.”
