Ui.Vision contains already some logic to adapt the images to changing screen resolutions, but this does not always work correctly. One way to make this work better is to lower the confidence level from the default 0.6 to e. g. add @0.45 to the image name. => e. g. Xclick | something_dpi_120.png@0.45
But even with this change, sometimes the better (or only) solution is to recreate the image on the second machine. Improving the image recognition further is on our todo list.
Another workaround is to use text recognition (OCR) instead. Text recognition is resolution independent! So instead of Xclick | image.png use XClickText | text... or XClickTextRelative | text…`
