Public bug reported: In that system only one display port is attached as seen by driver/X, but the image is displayed on both screen, but mirrored, when I switch to resolution 3840x1080 the image is stretched on both full hd displays. The drawback of this situation is when I want to stretch to fullscreen it stretches on both screens treated as one. This is not the case under Windows.
