If your product screens don't display correctly after being captured in Demoboost (i.e. you see empty spaces at the borders of your screen, or vice versa - some parts of the interface are cut off), you can fix the scaling by locking your demo to its original capture resolution.
This ensures that your demo screens maintain their original layout, even when viewed on devices with different screen sizes.
Follow these steps to adjust your demo settings and fix screen scaling.
This will open the Demo settings window.

In the Demo settings window, scroll down to the Screen size section.
Find the Lock to capture size option and enable the toggle.
When enabled, this setting displays your demo screens at their original captured dimensions, scaling them proportionally to fit the viewer's screen. This helps prevent layout issues caused by resizing.

Once you've enabled Lock to capture size, you'll see the Fallback size settings, where you can specify the original screen resolution.
There are two ways to configure it:
Option 1: Use the Automatically Detected Resolution
If you've recently captured your demo and are using the same device it was captured on, Demoboost can automatically detect your current screen resolution.
You can also enter the width and height manually if needed.

Option 2: Enter the Resolution Manually
If you're working with an older demo or configuring the settings on a different device, you'll need to enter the original capture resolution manually.
Important: Make sure you enter the original capture resolution, not the resolution of the device you're currently using. This ensures that your demo screens scale correctly.
Once you've enabled Lock to capture size and confirmed the correct resolution, click Save.
That's it! Your demo screens will now scale proportionally while preserving their original layout, giving your viewers a consistent experience across different screen sizes.
