WallPapers Please

[Pumciusz]

Hey, I just bought a new monitor, it's 1440p when my previous one was 1080. I was running a "slideshow" on Windows 10 Pro to change wallpapers every 30 minutes, but now that I have a higher resolution these wallpapers look like crap on my main screen.

So I was going to get some new 1440p ones, and I wonder if there's an option to run them from two different sources? I'd like to continue using the old 1080p ones on my 1080p monitor, and new 1440p on my new monitor, but If I just place them in the same folder, then it would be a cointoss if there's a pixelated mess on my main monitor or not.

If it's not possible in Windows 10 Pro, then can something like Wallpaper Engine do it?

Also is downscaling 1440p to 1080p wallpapers any good? And if it is, can I upscale my old wallpapers and then let Windows downscale them(It would solve the two sources problem).

I spoke of upscalling as I was reminded of this series by 2klicksphillip, in one of the videos that it got pretty good results at it.
