Microsft Windows 7. Anyway, the colors are a little faded. Not a big problem, but when I start m14x with linux, the colors are better, vivid. I'm not an expert about colors setting, but reviews speak about high saturation.
Maybe it's just me.
Try to do this:
1. right click on desktop, customize (i'm assuming it's like that in english, in italian it's "Personalizza")
2. on the left bar, at the bottom, click on display ("Schermo", in basso a sx)
3. there should be an option in the left bar with the administration shield logo called something like colors adjustment, or something like that ("Taratura colore" in italiano)
Check if from there you can do anything to fix the colors.
