The lock feature on Dell monitors is designed to prevent accidental changes to the display settings. It’s usually enabled by pressing a combination of buttons on the monitor, such as the menu button and the minus (-) button. When the lock feature is enabled, you won’t be able to adjust the display settings, such as brightness, contrast, and input source.

There are several reasons why your Dell monitor might be locked. Here are some of the most common reasons:
- Accidental Button Press: You might have accidentally pressed the combination of buttons that enable the lock feature.
- Child Lock Feature: Some Dell monitors come with a child lock feature that prevents children from changing the display settings. If this feature is enabled, your monitor might be locked.
- Input Source Lock: If you’ve connected multiple devices to your monitor, the input source might be locked, preventing you from switching between devices.
- Firmware Issues: Firmware issues can cause your monitor to malfunction, including locking the display settings.
