Windows 10 laptop start up screen black

[Gjac]

I went camping for a week when I returned my start up screen was black instead of having a picture on it. In addition various apps are also reversed instead of black lettering on a white back ground it is white lettering on a black background.There is also a purple border around the screen. Tried resetting defaults, removing battery for a few mins then reinstalling, they did not help. Any help would be appreciated.

Thanks 1492 and gorden three I believe it was the high contrast button. Before I saw your replies I remembered System Restore so I restored the system to a previous week and that fixed the problem. When I saw your posts I went in and disabled the high contrast option so it would not happen again.

If your screen looks like below, then high contrast is enabled. You should disable it as the keyboard switch combo can accidentally be pressed? Which is likely what happened in your case?

x2 sounds like high contrast or limited sight mode is turned on.

Turn on/off High Contrast

If you get to a login screen and then your screen goes black or blank, try the following actions:

Action 1: Try a Windows Key sequence to wake the screen.

If you have a keyboard connected, press the Windows logo key+Ctrl+Shift+B. If you’re in tablet mode, press the volume-up and volume-down buttons simultaneously three times within 2 seconds.

Screen is not completely black or blank, everything works only background is black and lettering is white.
