HUD image defects
Image 1 is compressed widthways. Image 2 is displayed twice. Images 3 and 4 are
distorted.
Fading
The incidence of light onto the windshield
or into the HUD in an inconvenient situa-
tion causes the image to fade.
Correcting Distortion (warping)
Should the image be distorted after a
change of windshield, the image display
can be improved using the Warping func-
tion. Warping is the technical term for the
improvement of the image display.
Note: It is only possible to adjust the head-up display vertically (rotation) and
correct the image in the event of distortion (warping) using the BMW
diagnostic system. Detailed information on the subject of Warping may
be found in the BMW diagnostic system.
