Troubleshooting
Downloaded from ManualMonitor.com Manuals
A blank screen appears / I cannot turn the product on
THE IMAGE IS TOO LIGHT OR TOO DARK.
The on screen adjustment menu (OSD) does not appear.
Check the connection status of the power cord.
(Connected using the D-sub cable)
Check the cable connecting the PC and the product.
(Connected using the DVI cable)
If the message appears on the screen even if the cable is
properly connected, recheck the input signal by pressing the [
] button of the product.
This occurs when the signal from the graphics card exceeds
the maximum resolution or the maximum frequency of the
product.
In this case, set up the appropriate resolution and the fre-
quency for the product.
1. This occurs when the power saving function is running.
If you click the mouse or press any key, the screen will be
turned on.
2. If the "Check Signal Cable" condition persists for more than
five minutes, Lossless mode will be activated. In Lossless
mode, the backlight of the monitor will turn off.
If you connect the DVI cable when the PC has booted up or if
you reconnect the DVI cable after disconnecting the cable
while using a PC, the screen may not be displayed because
some graphics cards do not output the video signal.
In this case, reboot the PC while the DVI cable is connected.
Blank spaces on the screen are not caused by the monitor.
The cause of the problem is the PC or graphics card, and can
be fixed by adjusting the screen size in the HDMI or DVI
option of the graphics card settings menu.
If the graphics card settings menu has no option to adjust the
screen size, update the graphics card driver to the latest ver-
sion.
(Please contact the graphics card or computer manufacturer
for details on how to adjust the screen settings.)
