Troubleshooting

Please check the following before requesting After-Sales service. If the problem continues, please contact your nearest 
Samsung Electronics Service Center.

 

Is the power cord connected properly?

Check the connection status of the power cord.

Is the <Check Signal Cable> message displayed on the 
screen?

(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.

Is the <Not Optimum Mode> message displayed on the 
screen? 

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.

Is a blank screen displayed and does the power LED blink at 
a 1 second interval?

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, the power saving function will be 
activated.

Did you connect with a DVI cable?

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 are found at the top and bottom of the screen 
when an [HDMI] or [HDMI-DVI] cable is connected to the 
monitor and PC.

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.)

Adjust the <Brightness> and <Contrast>.

(Refer to the <Brightness>, <Contrast>)

The display brightness can differ according to the mode set for <

Angle>.

If <

Bright> is set to <Dynamic Contrast>, the display brightness can differ according to the input signal.

Did you cancel the screen adjustment?

Check if the OSD Adjustment Lock function is set to Off.
