Samsung Monitor Locked Fix 🔒 | Easy Reset Guide (Step by Step)

🔒 1. OSD (On-Screen Display) Lock

Some Samsung monitors have a feature that locks the menu buttons so settings can’t be changed.

To unlock:

Press and hold the Menu (or Source/Menu) button on the monitor for about 10–15 seconds until the lock symbol disappears.

On some models, it may be the Enter or OK button instead.
