Windows 10, dual monitor setup. My main monitor is 1920x1080 but my other is at 1200. I set my background to image of 1920x1200 and it crops to fit the smaller screen and carries that cropped version over to the larger screen. It's a known issue apparently as noted in the link below. I tried the suggested workaround but it didn't help. Hoping maybe someone else has run into this and found a better solution?
