windows desktop wallpaper problem

I can’t seem to get custom pictures to display properly on my desktop. I’ve made sure I chose “center” and they are the exact dimensions of the screen resolution, but no matter what I try, every picture is offset from the top of the screen by about 30%. Any tips?

does a smaller pic center properly?

Does “Stretch” work?

Neither of those worked. I actually fixed it with a little app called Wallpaper Mover. Turns out the standard position had gotten messed up somehow.

Is the DPI of the picture the same as the DPI of your monitor?
