Chapter  08

Requirements Before Contacting Samsung 

Customer Service Centre

 

― Before calling Samsung Customer Service Centre, test your product as follows. If the problem persists, contact Samsung 

Customer Service Centre.

Testing the Product

Check if your product is operating normally by using the product test function.

If the screen is turned off and the power indicator blinks even though the product is properly connected to a PC, 
perform a self-diagnosis test.

Power off both the PC and product.

Disconnect the cables from the product.

Power on the product.

If the message 

Check Signal Cable

 appears, the product is working normally.

 

― If the screen remains blank, check the PC system, video controller and cable.

Checking the Resolution and Frequency

For a mode that exceeds the supported resolution(refer t

Standard Signal Mode Table

), the message 

Not Optimum 

Mode

 will appear for a short time.

 

― The displayed resolution may vary, depending on the computer system settings and cables.

Check the following.

Installation issue (PC mode)

The screen keeps switching on and off.

Check the cable connection between the product and PC, and ensure the connectors are locked.

Blank spaces are found on all four sides of the screen when an HDMI or HDMI-DVI cable is connected to 
the product and PC.

The blank spaces found on the screen have nothing to do with the product.

Blank spaces on the screen are caused by the PC or graphics card. To resolve the problem, adjust the screen size in 
the HDMI or DVI settings for the graphics card.

If the graphics card settings menu does not have an option to adjust the screen size, update the graphics card 
driver to the latest version.

(Please contact the graphics card or computer manufacturer for further details about how to adjust the screen 
settings.)

The power LED is off. The screen will not switch on.

Check that the power cable is connected properly.

 appears.
