Multi-monitor support (X & Y Axis)
Always set the Display Scaling in Windows settings to 100% so that the OCR Screen can accurately capture the display area
This issue occurs because what you see on the monitor is the result of windows scaling, but the OCR Screen captures the display area without any scaling (for more details, see Display Capture Sources in the OCR Master window)
In the VNTranslator settings, only the Display Source set to Electron can work to capture the display area with scaling more or less than 100%
