Question

my mouse can't go to my second moniter

Answer 1

I can help — first, a couple quick questions:
- Which operating system are you using (Windows 10/11, macOS, Linux)?
- Are the monitors supposed to be in Extended mode (separate desktops) or Mirrored/Duplicate?
- Did this ever work before or is it a new setup?

While you answer, try these common fixes (start with whichever match your OS):

If you’re on Windows 10/11
1. Quick display mode: Press Win+P and choose Extend.
2. Arrange monitors: Right‑click the desktop → Display settings → Identify. Drag the monitor tiles to match the physical layout (left/right and vertical alignment) → Apply. If the tiles are offset vertically the cursor can get “stuck” at an edge.
3. Check duplicate vs extend: Make sure “Duplicate” is not selected.
4. Fullscreen apps: If a game or video is fullscreen on one monitor it can capture the mouse. Try Alt+Tab or switch the app to windowed/borderless mode.
5. Update drivers: Update graphics drivers (NVIDIA/AMD/Intel) and try updating/replugging the mouse (try a different USB port).
6. Hardware/cables: Ensure the second monitor is detected and powered on. Try swapping cables or ports.
7. Multiple GPUs/docks: If you have integrated + discrete GPU or a docking station, try connecting both monitors to the same GPU/dock.
8. Reboot if needed.

If you’re on macOS
1. System Settings → Displays → Arrangement. Make sure “Mirror Displays” is unchecked and drag the blue displays to match your physical layout.
2. Drag the white menu bar to the display you want as primary (if needed).
3. Fullscreen apps can capture the cursor; exit fullscreen or use Mission Control to move windows.

If you’re on Linux
- X11: run xrandr to see outputs and use a command like
xrandr --output HDMI-1 --right-of DP-1
(replace output names from xrandr output) to place displays relative to each other.
- Wayland: use your Desktop Environment’s Display settings to arrange and disable mirroring.

Other possible issues
- Some utilities (cursor-locking tools, remote desktop apps, virtualization software, or multi-monitor management apps) can trap the cursor — close those.
- High DPI/scaling mismatches can sometimes cause odd behavior; try equal scaling on both displays to test.
- Try another mouse to rule out a hardware mouse issue.

If you tell me your OS and whether the monitors are detected in Display Settings (and whether the cursor reaches the edge at all), I’ll give exact steps or commands tailored to your setup.
