I've got a 28inch and a 32 right next to each other, and the 32 is 4K, and the 28 is 1920x1200. So this is the result.
It looks quite a bit better in person.
The wallpaper on the left is Bitday, it was a small thing that got kinda big on Reddit almost a decade ago, a cool wallpaper that changed with the time of day, it was re-implemented in Wallpaper engine and has been my goto for years.
It does change with the time of day.
I also just love Zenyatta.
