To connect the TV with your PC, make sure that your PC's graphic card supports UHD
resolutions.
For more information about the supported UHD resolutions, refer to "Supported Resolutions
for UHD Input Signals."
Make sure that the set-top box or cable box supports the content or broadcast for
UHD and set the resolution. For more information, contact your service provider.
When using a Samsung TV Plus
network speed is slow, the app may not work or the image quality may be poor.
The compression of video content may cause picture distortions, especially in fast moving
pictures from sports programs and action movies.
If the signal reception is weak or poor, screen distortion may be visible but it is not a
malfunction.
Mobile phones used close to the TV (within 3.2 ft) may cause noise on analog and digital
channels.
If you're using a Component connection, make sure that the Component cables are
connected to the correct jacks.
Incorrect or loose connections may cause color problems or a blank screen.
