Writing depends on 'Writing mode' on Settings menu:

• Strict - image can be written only to that type of screen which was used during emulation (initial screen).
• Size - image can be written to any screen with the same resolution (example Waveshare 2.13 inch to GDEY0213B74)
• Vendor - image can be written to any screen with the same vendor as in initial screen.
• Free - image can be written to any screen without restrictions.

When initial image is smaller then target screen, then it will be copied to target and other part in target will be filled with black color. When initial image is larger then target screen, then it will be cropped to fit target screen size.
