With support from your video card for that resolution, it
should display the aquarium from end to end with no scrolling, since the background was built for dual 1920x1080 screens, and that's essentially what that is, just in one monitor.
I hope so, Doc, but looking at this image
https://www.serenescreen.com/product/maquarium3/ It looks like 32:9 at least when I measured the image. Hmmmm.. It would sure make my day. I emailed Samsung and asked them to download the trial version of MA3 and to please let me know how it fit.
