In multi-monitor desktop setups on Windows, touch input from external, secondary, or portable touch screens is frequently mapped to the wrong display or sent to the primary monitor.

TouchScreen Monitor Selector fixes this with a single click. It detects all connected monitors and HID touch digitizers, providing an interactive visual desktop layout and instantly redirecting touch coordinates to the selected screen in real time (using undocumented kernel Win32k APIs) without requiring a reboot or sign-out.

Features

  • Proportional visual canvas of multi-monitor setups matching real EDID names (e.g. LG ULTRAWIDE, Display).
  • Real-time touch redirection via USER32.dll Ordinal #2532.
  • Persistent mapping saved to Windows Tablet PC registry (HKLM\SOFTWARE\Microsoft\Wisp\Pen\Digimon).
  • Automatic detection of HID touchscreens and pens with VID/PID and contact points.
  • Quick launchers for Windows Tablet PC tools (MultiDigiMon and TabCal).
  • Modern Windows 11 dark UI, System Tray integration, and multilingual support (English, Spanish, French, German, Japanese).
