If it is not serious, I wouldn't bother, because chances are, you may get a refurbished unit, and it could be even worse than what you have now.
By right, Dell will send you a replacement unit which you swap with your malfunctioning unit. That's why I like Dell so much. Everytime I have a problem with my monitors, I would report it and they will send a replacement the next business day. I just have to disconnect my monitor and pack it into a box; or wait until the replacement monitor arrives and put the old monitor in its box. Then the deliver guy takes the old monitor back.
