The image of the screen mirroring appears blurry

Images may appear blurry for the following reasons.
Please check each method to resolve the issue.

NOTE: The video or audio may be interrupted or stopped depending on the environment of usage

•  The resolution of the content being played on the connected device is low (720p or 480p).
    Please play high resolution content (1080p).
• The screen mirroring output resolution of the connected device is low (720p etc.).
  Even if the content resolution is high, it may appear blurry due to the low output resolution of the connected device.
  In this case, try to connect directly to the TV by HDMI or MHL cable, or connect by using home network via router.
  
  NOTE: Some models do not support the MHL connection. For specification of the TV, refer to the manual.
