This is a current open feature request.
I have a work around as previously posted:
I have overcome this by setting my dual monitor wallpaper at 105% and shifting each image 65 px horizontal (-65 on one & +65 on the other) on the monitor settings adjustment tab.
I measured my bezels (from image edge to bezel edge) in mm & converted to px (google search)
It was an easy fix and it allows 1 px shifts. My images appear seamless across the monitors. This doen't work for the screensavers.
Good luck.
