The background image on an interactive whiteboard might appear very small for several reasons:
Incorrect Resolution: If the image resolution is too high for the whiteboard's display settings, it might appear smaller than intended. For example, a 4K image might be too detailed for a standard 1080p display.
Scaling Issues: The software or settings on the whiteboard might not be configured to scale images properly. This can cause images to appear smaller if they are not adjusted to fit the screen size.
Aspect Ratio Mismatch: If the aspect ratio of the image does not match the aspect ratio of the whiteboard, it might appear distorted or smaller. For instance, a 4:3 image might look small on a 16:9 screen.
Zoom Level: The zoom level of the whiteboard software might be set too low, making all content, including images, appear smaller.
Hardware Limitations: Older or lower-end interactive whiteboards might have hardware limitations that prevent them from displaying high-resolution images properly.
Solution Example: To resolve this issue, you can try adjusting the image resolution to match the whiteboard's display settings, scaling the image within the whiteboard software, or changing the zoom level. For more advanced solutions, consider using cloud-based services like Tencent Cloud's Interactive Whiteboard Solution, which offers features to optimize image display and ensure compatibility across different devices and resolutions.
