If you plan on using a splitter cable....both monitors connected using it WILL DEFINITELY display the same image at ALL TIMES. There is physically only a single source for an image to both screens so it MUST be the same image.

One caveat: there are some weird low-profile video cards (I have one in a Dell Optiplex 270 small form factor box) that use a unique DVI connector on the card. This connector REQUIRES a special splitter cable to connect two DVI monitors. But, the DVI connector on the card is NOT a normal DVI connector so there shouldn't be any confusion.

G'luck all,
