How to Stop Your Mouse Drifting Onto the Second Monitor
You don’t need a game running for the cursor to wander. Here’s how to add friction — or a wall — at the screen edge.
Two fixes, pick your strictness
Option A — Sticky resistance (recommended for daily use)
In the Cursor module, set a resistance value. Now the cursor only crosses monitors when you move the mouse fast enough. Slow, accidental drifts — the kind that happen while reading or reaching for coffee — get stopped at the edge. Deliberate moves cross normally.
Option B — Hard lock (for focus sessions)
Bind “Lock cursor onto screen” to a hotkey. While locked, the cursor cannot leave the current monitor at all. Ideal for presentations, focused writing, and gaming.
Fine-tuning
- Start with a medium resistance and nudge it up until accidental crossings stop but deliberate ones feel instant.
- If you use monitors of very different sizes, check the monitor layout first — a misaligned edge map makes the cursor “jump” at corners.
- Combine with center-snap: one hotkey warps the cursor back to the middle of your main screen when you lose it.
Frequently Asked Questions
Why does my mouse keep going to my second monitor?
Windows lets the cursor cross freely by default, and with no friction at the screen edge even a slow drift crosses over. DMT’s sticky resistance adds that friction back, or a hard lock removes crossing entirely.
Can I stop the mouse moving to the second monitor without software?
Partially: some games have a “confine cursor” option, and Windows display settings let you arrange monitors so edges don’t align. But a tool like DMT is the only general fix that works everywhere.
Does sticky resistance slow down normal work?
No — it only resists slow crossings. Move the mouse deliberately and it crosses normally; only accidental drifts get caught.
