just get this monitor adapter cord to hook up my second monitor . my computer only have one VGA port . I go to bestbuy and be tell I would have to spend upward of $ 100 to get a cord then a adapter for the cord in order to hook up dual monitor . I find this cord on Amazon and it work perfectly ! I be so excited . it be so easy to set up and now I have my dual monitor work ! Super fast ship too ! definitely recommend this product if you do not have two VGA port for a dual monitor setup .
