Windows 8, Windows 10 + Unexpected Output Window Size
From MXWendler Wiki
This applies to Windows 8, 8.1, 10 and MXWendler version 5.0 and above
- You want to open an output window but the output window does not appear at the expected location and does not have the expected size.
- In Display in System Settings check the setting Change the size of app, text, and other item. Set the slider to 100%.
- If the setting is not exactly 100% Windows reports virtual monitor sizes to applications to equalize high-resolution monitor scaling.
