I wonder if it's something to do with the HDMI lines?
Mine:
HDMI-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 160mm x 90mm
Yours:
HDMI-1 connected primary 1920x1080+1280+0 (normal left inverted right x axis y axis) 160mm x 90mm
Yours has the 1280+0 whereas mine that's 0+0.
I have no idea what the significance of that difference is but someone might know perhaps.
