YouTube Not Showing Full Screen on Samsung Smart TV? Here’s How to Fix It

If you are getting inconsistent picture sizes on your Samsung TV, try the solutions below one by one until you find the one that spells out success for you.

Solution 1: Power Cycle Your Samsung TV

Software glitches are the prominent reasons why YouTube videos are not showing up in a full-screen window. This can be easily fixed just by power cycling the device. I have personally tested this method and it works most of the time.

Here’s how to power cycle your TV:

  3. Wait for 2-3 minutes and then plug the power cable back into the power socket.

Now, connect your Samsung TV to the internet. Launch the YouTube app and start watching your favorite videos in full screen.

Solution 2: Clear the YouTube App Cache and Data

If the YouTube video’s small size issue persists, you can try clearing the app cache and data. It should fix issues within the YouTube app.

  1. Turn on your Samsung TV.
  2. Press the Home button on your TV remote and select Settings.
  3. Select the Apps option.
  4. Find YouTube in the app list and select it.
  5. Select Clear cache and press the OK button on your remote.
  6. Select Clear data and press OK.

Although an outdated YouTube app should work just fine, it can bring numerous problems. The app is regularly updated to improve the software experience. Plus, it includes fixes to known issues. So, you must update the app, even where there are no issues.

Simply launch the Google Play Store, search for YouTube, and hit the Update button. Once the app is updated, launch it and play a video to verify the solution.

Solution 4: Reinstall the YouTube App

There could be an issue with YouTube app files on your Samsung not allowing the videos to show up in full screen. You can uninstall and reinstall the app as an attempt to fix this issue.

  1. Press the Home button on your TV remote.
  2. Go to Apps.

Play a YouTube video to check if the problem is sorted out.

Solution 5: Adjust TV Picture Size Settings

If the correct picture size is not set, YouTube videos will either show up too big or too small. The standard aspect ratio for YouTube videos is 16:9. You should be using the same for your Samsung TV.

Here’s how to do it:

  1. Press the Home button on your TV remote.
  2. Select the Menu option.
  3. Select Settings and then choose All Settings.
  4. Select the Picture option.
