Source window (HDMI) issue
Blank spaces are found on all four sides of the screen when
an HDMI cable is connected to the product and PC.
The images on the screen look distorted.
The screen is not clear. The screen is blurry.
The screen appears unstable and shaky.
There are shadows or ghost images left on the screen.
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 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.)
Check the connected cable. Compatibility is not guaranteed if you use a cable that has not
been supplied by Samsung.
Set the resolution and frequency to the recommended level.
Check that the resolution and frequency of the PC and graphics card are set within a range
compatible with the product. Then, change the screen settings if required by referring to
'Preset Timing Modes'.
