I have a Windows 11 computer, but suddenly the screen turned black and white. I asked a lot of AIs, but none of them gave me a good answer.
Hello,
Can you go to Windows Settings > Accessibility > Color filters, please make sure the Color Filters toggle is turned OFF.
In addition, please go to Accessibility > Contrast themes, make sure the dropdown menu for Contrast Themes is set at None.

倘若上述独立顾问 @EmilyS726 提及的，Windows设置选项并没有问题，建议先进行一次完整的安全扫描。用Windows 11自带的安全中心（Windows Defender），或第三方的专业工具如Malwarebytes等。
