Touch Accuracy Offset

Touch Accuracy Offset

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 in relation to where it shows on the display, please check 2 things:



1. Scaling applied in the GPU Control Panel

Example for NVidia RTX A2000 Graphics Card Control Panel:


In NVIDIA Control Panel, under Display, select Adjust desktop size and position, then select No scaling, and click Apply





2. Advanced Display Settings (Windows)

  1. Open Windows Display Settings (Right click on Desktop and select Display Settings)

  1. Select the appropriate display, if applicable

  1. Click on Advanced display under Related settings

  1. Ensure the details are the same next to Desktop mode and Active signal mode, if you see different values, click on Display adaptor properties

  1. Click on List All Modes

  1. Select any other resolution and refresh rate in the list that appears, and click on OK

  1. Repeat this step, then select the desired resolution and refresh rate from the list and click OK
Test the touch accuracy again, and if needed, perform the calibration in Displax Connect.
