If the camera is set for indoor incandescent lighting then a white computer screen will appear blue. And that's what I'm seeing in that picture. The two "Welcome to Macintosh" is due to the vertical retrace problem the OP was asking about. Normal screen retrace can cause parts of the screen to be dark in a photo but it can't cause something to appear in two places. The short diagonal white(ish) line in the lower right corner is also a sign of the retrace problem.
