If the initial screen (the login screen) appears, boot the computer in the applicable mode (the safe mode for Windows ME/2000/XP) and then change the frequency of the video card.

(Refer to the Preset Display Modes)

Note: If the initial screen (the login screen) does not appear, contact a service center or your dealer.

Adjust the maximum resolution and frequency that the monitor can properly handle.

The monitor is in PowerSaver mode.

Press a key on the keyboard or move the mouse to activate the monitor and restore the image on the screen.

If the monitor does not respond to the Power button, it was in DPMS (power- saving) mode and turned off when the button was pressed. Press the Power button once more to turn the monitor on.

You may get a blank screen if you boot the system before you connect the DVI cable, or disconnect and then reconnect the DVI cable while the system is running as certain types of graphic cards do not send out video signals. Connect the DVI cable and then reboot the system.

Check the signal cable connection.

Make sure the video card is fully inserted in it's slot.

Reboot the computer.
