Hi RB,
It looks like you accidentally switched one of the accessibility or display modes while traveling.
Have you already tried the Q&A Assist suggestions? In addition, could you confirm:
- Is everything inverted (white > black, black > white), or just darker overall?
On Windows 11, pressing “Ctrl + Windows key + C” toggles Color filters (including Invert).
- Try pressing “Ctrl + Windows key + C” once, this often immediately returns the screen to normal colors.
If that doesn’t fix it, based on your description, the next most likely cause is High contrast mode being turned on by shortcut:
- Press “Alt + Left Shift + Print Screen”
- If prompted, choose “No” (to turn off high contrast)
If the screen just looks dark (not inverted), you can switch back to the normal white/light theme as suggested by Q&A Assist:
- Open “Settings”
- Go to “Personalization” > “Colors”
- Set “Choose your mode” = “Light”
