Question: Display Reduces Size at Wake

When waking my MacBook from sleep, the lock screen display is reduced in dimensions. I do not know if this is a software issue, because pre Sierra 10.13.2 this has never happened. However, there was another display issue before the update that I won't get into, because it has been replaced by this one. Curious if anyone else has experienced this?

The screen should be filling out to the black bar region of the screenshot taken below, just to get rid of any confusion. I have a 2015 13" Retina MBP.

Answer:

Resetting the System Management Controller (SMC) can be done anytime, with impunity.


It can be especially helpful when it seems like your Mac "forgot about" some hardware item.

Hi zachmichieli,

I understand that your MacBook Pro shows the login screen at the wrong resolution when you wake it from sleep. I'm happy to provide some help for this issue.

I recommend resetting your NVRAM and SMC, which can help with display and sleep related issues:
