A Mouse Lock Guide explains how to confine your cursor to a single screen or game window, preventing it from drifting onto a second monitor during intense gameplay. This is a common issue for PC gamers using multi-monitor setups, often causing the game to minimize or lose focus during a stray click.
The primary methods used to lock and confine a cursor include native game configurations, Windows settings, and dedicated third-party tools. 1. Built-In Game Settings
Most modern PC games include native toggle options to handle cursor containment.
Exclusive Fullscreen Mode: Switching your video/graphics settings from “Borderless Windowed” to “Exclusive Fullscreen” forces the operating system to prioritize the game window, naturally locking the cursor inside it.
“Confine Mouse” Toggles: Games like Path of Exile or various RTS/MOBA titles feature an explicit toggle in their UI settings named “Confine Mouse to Window” or “Lock Cursor to Screen” specifically to aid edge-scrolling. 2. Third-Party Cursor Utilities
When a game’s native fullscreen mode fails to trap the cursor, players rely on lightweight, background utilities:
Dual Monitor Tools (DMT): A highly popular, free open-source suite. Under its Cursor > Sticky options, you can define a dedicated hotkey (e.g., Alt + Scroll Lock) that completely locks the cursor to the active monitor until pressed again.
Cursor Lock: A classic utility that uses a command-line wrapper to automatically open a game executable and strictly hook the mouse cursor into that program’s specific window boundaries.
CursorNode / Lock Cursor Tools: Alternative applications that let you restrict the mouse boundary to any chosen active window using a basic hotkey plus left-click combination. 3. Windows Native Quick-Fixes
