Hi @kjstech,
If you are using spacedesk Windows 10 Viewer app (from Microsoft Store), you can disable the screen view transformation via Settings -> Display -> View transformations.
If you are using spacedesk Windows 7 Viewer app (Desktop version 0.9.37), the option to disable the screen view transformation is not yet available and might not be available any time soon.
We are currently very busy with higher prioritized features and bug fixes.
