Displays and placement

Fit, fill or stretch

Fit preserves the full image with possible margins. Fill preserves aspect ratio but crops overflow. A portrait display does not rotate the video automatically. Stretch is a separate wallpaper mode that can distort proportions; the composition editor uses fit or fill.

Numbers, frames and sound

Wallpaper zoom supports 25–300% and position −100–100%, using sliders or numeric input. Frame rate and maximum resolution default to Source. A 120fps video limited to 60fps keeps its duration and speed, but shows fewer frames. Reducing on-screen size alone does not reduce the source’s decoding resolution.

Reconnect a monitor

The app remembers wallpaper and display settings. It prefers the stable display identifier, then a unique match based on name, pixel size and built-in/external status. Ambiguous matches require a manual choice. The app must be running to restore a newly connected display.
