Help with Hitachi CML174SXW LCD I have a three month old Hitachi CML174SXW display monitor. I cannot seem to access the "auto and input select" function, all the remaining functions appear to work properly. When I attempt to select either auto or digital the screen blanks out for about 5 sec (normal) but then returns to a normal non menu windows screen. If I go back into the menu it remains set on analog no matter how I try to set it. It is connected through a high end DVI cable to the DVI out on a Nvida GeForce 5900. How can I get this monitor to accept a DVI input, or could it be malfunctioning? Thanks in advance
