Spanned Display Touch Calibration Incompatibility with ForceMouse Driver Mode
Audience: Public / Elo Customers, IT Administrators & Video Wall Integrators
Article Type: Driver Compatibility & Architecture Limitation Notice
⚠️ Operational Architecture Limitation:
When the Elo Multi-Touch Driver for Windows is installed or operating in Forced Mouse (ForceMouse) mode, multi-monitor touch coordinate calibration is not supported in Spanned Display video mode. There are no software workarounds to calibrate spanned displays under ForceMouse emulation.
Technical Explanation
In ForceMouse mode, the Elo driver bypasses standard Windows Digitizer / Pointer input frameworks, converting all incoming touch packets into legacy single-pointer relative mouse click events.
Because Spanned Display configurations combine multiple physical monitors into a single virtual canvas (requiring multi-point matrix mapping across distinct display handles and grid coordinates), the simplified mouse emulation layer cannot resolve per-screen physical boundaries.
Recommended Configuration Path
- Reinstall Driver in Standard Mode: Reinstall the Elo Multi-Touch driver using the default Windows Touch (HID Digitizer) mode rather than ForceMouse.
-
Configure Spanned Mode: Follow the standard spanned setup procedure and enforce 3-point driver calibration in
EloOptions.ini(DriverCalibration = 1).
