    Play 1080P videos, 720P videos with lossless quality.

Solutions 9: Improve the Internet speed

The quality of your home or mobile network can affect how smoothly YouTube videos play, and whether videos play in HD.

Check the YouTube video's resolution and the recommended speed needed for the video to play. The table below shows the approximate speeds recommended to play each video resolution. If your internet speed is below the requirement, you will fail to play YouTube video.

Video Resolution Recommended sustained speed
4K 20 Mbps
HD 1080p 5 Mbps
HD 720p 2.5 Mbps
SD 480p 1.1 Mbps
SD 360p 0.7 Mbps

The actual speed that your device gets may vary from the number given when you run an 'internet speed test.' The difference can be due to numerous factors including:

  1. Wi-Fi performance
  2. Time of day
  3. How your ISP connects to YouTube
  4. How many devices are on your network: If there are a few devices on your network, then the connection is shared between them. Using numerous devices on the same network may reduce the speed that your device gets.

You can try to improve your internet from the factors above.

Part 3: Other Issues That May Affect YouTube Playback

If the solutions above don't work, you can check this part of some special situations, which may also cause failure of YouTube playback.

Situation 1: Age-restricted content

Sometimes content doesn't violate YouTube's policies, but it may not be appropriate for viewers under 18. Age-restricted videos may not be viewable to users who:

  1. Are under 18 years of age
  2. Are signed out
  3. Are watching YouTube videos embedded on most third-party sites

Situation 2: Restricted mode

Restricted mode is an optional setting which will prevent from pushing potentially mature content to you or others using your devices may prefer not to view. When Restricted Mode is turned on, comments may not be viewable. You can turn Restricted mode on or off.

Situation 3: Account error issues

When there is account error issue, you can not access to some certain content. If you're having trouble signing in with your YouTube username, try signing in to your account by entering your full email address. Then, enter the same password you've been using to sign in to YouTube.

Part 4: Another Way to Play YouTube Videos on Your Smart TV

Apart from the solutions introduced above, there is actually another way to successfully play YouTube videos on smart TV or basically any kind of TV. Instead of installing the YouTube app on your smart TV and watch the videos through the app, you can download your YouTube videos in advance, and then burn the downloaded videos to a DVD disc to play on your TV.

YouTube-to-DVD

Comparing to other YouTube video playing approaches, this approach has multiple advantages. First, because you don't need the internet connection to watch YouTube videos, the video watching experience won't be interrupted by any internet connection related problem. Second, for those TVs that cannot properly install a YouTube app, this approach can give the same video playback experience without the app. As long as you have a video downloader tool and a DVD burner tool on your computer, you can watch basically any YouTube video on your TV even if the TV is not a smart TV.

Although the process may look complicated at first, it's actually pretty simple as long as you have the right tools. In the following, I will show you what applications you need in order to watch YouTube videos on your smart TV with this approach, and also show you the detailed steps so that you can quickly finish the video downloading and DVD burning process, and start enjoying your favorite YouTube videos on your smart TV.
