Here are some Windows 10 Hero Image wallpapers that I made using PS. They are all 16X9 aspect ratio 4K and will work fine with 1080P or 3X2 aspect ratio devices like the SB or SP4.
You're welcome.
I love #3 btw, I use that for my wallpaper on all my devices, after using this I can't go back to the stock Hero Image...it just looks so "plain" now.
