Final answer:
To achieve full screen on a Samsung Smart TV, use the remote to access picture size settings or select the appropriate option directly with a button like 'Picture Size'. The exact process can vary by model and content source. For external devices or apps, ensure their output settings match the TV's resolution.
Step-by-step explanation:
To go full screen on a Samsung Smart TV, you usually need to use the remote control that came with your TV. The process may vary depending on the model of your Samsung TV and the type of content you are viewing. Generally, you can press the button that says 'Picture Size', 'P.Size', 'Aspect Ratio', or something similar to cycle through the available screen sizes until you find the full screen mode. For content from external devices or apps, make sure the device or app output settings are set to match your TV's resolution for a full screen experience without any black bars.
In some cases, you may need to access the TV's menu system to adjust picture size settings. This can usually be done by pressing the 'Menu' or 'Home' button on the remote, navigating to 'Settings' or 'Picture', and then selecting 'Picture Size Settings' or a similar option to adjust the available viewing options to full screen.
If you're using an app and not getting a full screen experience, you might need to look for a full screen icon within the app's playback controls or check if the app's settings menu has an option to enable full screen playback.
