Thumbnails Too Small For Videos and Small Images

[LionelHolt]

I need large thumbnails because of my 4K display, unless there's a scaling option for thumbnails?

So I select the maximum via: View » Thumbnails size » 768x576

That works fine except for videos (e.g. .mp4), even when the video resolution is greater than 768x576, and images that are not larger than 768x576.

Those thumbnails display at what appears to be 192x144.

For images specifically, both the height and width must be larger than 768x576 or else they drop down to 192x144.

Is there a way to make video thumbnails display at the selected size and for small images to stretch to fit the thumbnail window?

could you post a screenshot?

Folders are also displayed with thumbnails much smaller than the largest setting.

you need to change settings>Catalog - Width/Height, and use 'View>Rebuild thumbnails'

Thank you!
