DISPLAX Service allows you to limit the maximum number of simultaneous touches reported by a touch controller. This is useful for performance optimization, application compatibility, and filtering out unintended or excessive touch input.
By defining a maximum touch count, the system will ignore any additional touches beyond the configured limit.
You may want to set a touch limit when:
Running applications that support only a fixed number of touches
Optimizing performance on low-resource systems
Reducing unintended multi-touch input
Using touch sensors in public or high-traffic environments
Testing or debugging touch behavior
To see the current maximum number of touches reported by the device, run:
displaxservice -a 127.0.0.1 --tmax
This command returns the current touch limit configured for the connected device.
To limit the number of reported touches to 10, run:
displaxservice -a 127.0.0.1 --tmax 10
The device will now report a maximum of 10 simultaneous touches.
Touches beyond the defined limit are ignored, not queued.
The optimal value depends on both the hardware capabilities and the target application.
Some operating systems or applications may impose their own touch limits.
Changes take effect immediately unless otherwise specified by the device firmware.
Match the touch limit to the maximum supported by your application, otherwise leave it at the maximum (factory default).
Reboot or reinitialize the touch controller if behavior appears inconsistent after changes.
