The only reason I can think of why you could have "lost" only the purple dots (if you can still see the white stars and yellow constallations) is something broken in the "red" chain of graphics card, cable and screen - maybe a broken graphics card or just a loose contact on the cable. It may also be a change in the color adjustments of the monitor or the graphics driver.
Can it be fixed?
