Protection) support can delay the time taken for a TV
to display content from an HDMI device.
• If the TV does not recognise the HDMI device and
no picture is displayed, switch the source from one
device to another and back again.
• This is an Ultra HD TV. Some older devices -
connected with HDMI - do not recognise an Ultra HD
TV electronically and might not work correctly or
show distorted picture or sound. To avoid the
malfunctioning of such a device, you can set the
signal quality to a level the device can handle. If the
device is not using Ultra HD signals, you can switch
off Ultra HD for this HDMI connection.
If the picture and sound of a device connected with
HDMI is distorted, check if a different
HDMI Ultra
HD
setting can solve this problem. In
