Gonna have to look through some of those, I change my wallpaper way too rarely. Perhaps I should clean up my desktop as well!

so lets get this straight you have a 4K 16:9 wallpaper, but you don't have a 4K monitor or 4 1080p screens in a 2X2 grid. WHat do you do just break the image up across random screens? Or do you just have a 4K wallpaper for the hell of it and just scale it to each monitor?

I'm going to need pics

This is mine :D, it's normally either Shiina Ringo, Final Fantasy, Deus Ex Related thing, or default because I reformat computer way too much, and become to lazy...

I made custom one with this on my 1280x1024 monitor... too lazy to upload mine :P

I get all my wallpapers from Dizorb and Zixpk. Unfortunately, the sites are both no more. Thanks to Google, you can still find most of their wallpapers, though they are a bit harder to find, now. Especially in some of the less commonly used resolutions. Anyway, here're some of my favorites.

Wait so your 4K wallpaper is for someone elses setup? Now I am even more confused

A 4K wallpaper for not your setup, that isn't a 4K monitor, isn't a 2X2 grid of 1080p monitors, that uses more than 2 monitors. Yea I am definitely going to need a photo of this.

And I am not doubting that you have a setup capable for displaying a resolution of 4K or higher, I am just not sure how it's set up considering you have shot down every configeration I can think of to achive 16:9 4K to match the image. If you said you were using 4 4K projectors to achive 8K and were just using a 4K wallpaper because you couldn't find an 8K version I would belive you.

Currently I have the Dragon's Crown unlockable arts in 1440p on rotation. They are so damn sexy:
