I am facing a weird issue. I have basically three monitors:
2 x 34 inch ultra wide LG monitors which supports up to 3840x2160 screen resolution.
1 x 22 inch Dell monitor which supports up to 1920x1080 screen resolution.
One 34 inch monitor connected to on-board Intel Graphic Card HDMI port:

Maybe the 22inch monitor screen resolution 1920x1080 takes precedence on each reboot and the system resets the wallpaper resolution to the same?. I don't know why it happens all of a sudden.
