Why doesn't the monitor display an image with a resolution lower than its native resolution range at the actual scale even by pressing the Auto button?

Displaying an image with a low resolution at the actual scale is usually possible if your monitor has and settings in the ScreenManager menu. The setting procedures are: 1. Set the resolution at setting in the ScreenManager menu. 2. Run the screen adjustment software in the bundled EIZO Utility Disk and manually adjust "Clock", "Phase" and "Position". (The software directs you to press the button. However, do not press the button, otherwise the existing resolution settings are reset.)
