"I have a HP 25es display on a mac mini (late 2014)... no problems until I installed high sierra a few days ago and EVERY time I have logged in since I have had to reset resolution. does not matter if I manually set "scaled 1080p" or "default for display" when I log in I am forced to go to systems settings to return to 1080p, possibly an overscan issue but unable to find ANY posts on a fix"

"display resize issues with mac osx high sierra waking from sleep
I just upgraded to Mac OSX High Sierra. I have the Mac mini server late 2012. Whenever my mac mini goes to sleep and I awake the computer and login, The screen needs to be resized, actually the correct setting is already there saved, default display and underscan, but I have to bring up that screen every time from display settings when it goes to sleep, as to click on the underscan drag icon, I don't even need to adjust it, just clicking on it, it fixes the screen to the right screen size. My mac mini is attached via hdmi to a SHARP tv. Everything was fine on Mac OSX Sierra, but after the update to High Sierra. I have this issue. Is this a bug? Is there anything I can do? Thanks in advance."
