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.
2
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 to Standard Signal Mode Table ), the message
Not Optimum Mode will appear for a short time.

The displayed resolution may vary, depending on the PC 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 PC manufacturer for further details about how to adjust the screen
settings.)
