If the cable is connected properly, press the [
button repeatedly to confirm that the product is set to the cor-
rect source and that it is receiving an input signal.

rate) capability of the product.

quency for the product. For the correct values, see the Stan-
dard Signal Mode Table.

To turn on the screen, click the mouse or press any key.
If you connect the DVI cable while the PC is booting up or if
you reconnect the DVI cable after disconnecting the cable

ditions.
