After obtaining an optimal touch performance and calibrating a touch sensor, if you find there is an offset to the accuracy of where the physical touch is compared to where it shows on the display, please ensure scaling is neither applied in the OS Display settings, nor the GPU Control Panel.
OS Display Settings (Example for Windows):
In Windows Display Settings, under Scale & Layout, set Scale to 100%
Graphics Card Control Panel (Example for NVidia RTX A2000):
In NVIDIA Control Panel, under Display, select Adjust desktop size and position, then select No scaling, and click Apply
