When I connect a new PC to my monitor and start up the computer all I get is a blank screen. The monitor is fine, it works with another PC and the PC sounds as though it's working fine. Normally the yellowy-green light on the front of the monitor is on when in use but with the new PC it flashes. The menu button doesn't bring up any options (normally it would bring up brightness control etc.). I have 4 identical computers to set up and have tried one other which has the same problem.
The PC is a HP Compaq DX2200 running XP Pro and the monitor is a Compaq V710. The computers are brand new, delivered yesterday.
