NO, that's not normal. Excluding any RF source or outside influence, the monitor should be as solid as a rock. Since, this is new, start the warranty process, the quick way is return to source of purchase as usually you have 15-30days, no questions(God only knows) asked, maybe return the whole system if they get lippy. Then settle for a better system or whole replacement system or just the monitor to make you happy, otherwise accept your money back. Don't waste time Happy
