    Hi Putu Aditya W.,

     

    Welcome to the Apple Support Communities! I'm sorry to hear you are having this issue with your MacBook Pro. If you are having issues with your display image not filling the entire screen, you may want to double-check your resolution settings as detailed in the following article. In particular, you may want to see if the "Default for display" option has become unchecked; this is generally going to provide the best image on built-in displays:

     

    (Note: Although this article is aimed at external displays, the steps would generally apply for internal displays as well)

     

    Adjust video settings

    If there's no image on your display, try adjusting your display's brightness or contrast. If there's still no image, or the image appears torn or scrambled, try selecting a different video resolution in System Preferences.

    Adjust brightness

    • If you're using an Apple Display, press the increase brightness key F2 key image  on your Apple keyboard. To adjust the brightness of a secondary display, press Control-F2.
    • If you're using a display that's not made by Apple, check the documentation that came with your display to see if it includes built-in controls for adjusting its brightness or contrast.

    Change your display resolution

    1. From the Apple menu, choose System Preferences.
    2. Click the Displays icon.
    3. Click Default for display. If you see more than one resolution listed, choose a resolution and refresh rate. If the display turns off when you change resolutions, press the escape key to undo the change. 
      displays preferences window

    If you can't change the resolution of your display because you can't see an image, restart your Mac in safe mode to reset the display resolution to defaults.

    If starting in safe mode doesn't resolve the issue, reset your Mac's NVRAM and SMC to reset the video ports on your Mac to their defaults.
