brand new owner of what I thought would be a great exp with a dell projector. My trouble is with the blank screen. The video mute warning at the bottom of the screen does not go away...it stays there. Dell says that is the way it works, no other help and thier customer service won't even consider an exchange or return. First projector I have ever used where words stay up on a blank screen. Anyone have any advice? I am very upset with Dell and am fed up with thier "customer no service". I wonder what Michael would think if he knew. Maybe a registered letter is next.
