Check 1 : Increase the scanning resolution if the image is jagged.
Resolution
The data in the image you have scanned is a collection of dots carrying information about brightness and color. The density of these dots is called "resolution", and resolution will determine the amount of detail your image contains. The unit of resolution is dots per inch (dpi). Dpi is the number of dots per inch (2.5 cm).
The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less detail.
Check 2 : Set the display size to 100 %.
Some applications do not display images clearly if the display size is too small.
