HDMI and USB
HDMI
• Note that HDCP (High-bandwidth Digital Content
Protection) support can delay the time taken for a display
to display content from an HDMI device.
• If the display does not recognise the HDMI device and
no picture is displayed, switch the source from one
device to another and back again.
• If the picture and sound of a device connected to HDMI
is distorted, connect the device to another HDMI port
on display and power reboot your source device.
• 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 Help, press the
color key Keywords and look up HDMI Ultra HD.
• If there are intermittent sound disruptions, make sure
that output settings from the HDMI device are correct.
• If you use an HDMI-to-DVI adapter or HDMI-to-DVI
cable, make sure that an additional audio cable is
connected to AUDIO IN (mini-jack only), if available.
HDMI EasyLink does not work
• Make sure that your HDMI devices are HDMI-CEC
compatible. EasyLink features only work with devices
that are HDMI-CEC compatible.
HDMI eARC is not working well
• Make sure the HDMI cable is connected to HDMI 2.
• Make sure the Ultra High-speed HDMI cable is used
for eARC connection.
• Only one eARC device is available at a time.
No volume icon shown
• When an HDMI-CEC audio device is connected and you
use the display Remote Control to adjust the volume
level from the device, this behaviour is normal.
Photos, videos and music from a USB device do not
show
• Make sure that the USB storage device is set to Mass
Storage Class compliant, as described in the storage
device's documentation.
• Make sure that the USB storage device is compatible
with the display.
• Make sure that the audio and picture file formats are
supported by the display.
Choppy playback of USB files
• The transfer performance of the USB storage device
may limit the data transfer rate to the display which
causes poor playback.
Network
Wi-Fi network not found or distorted
• Microwave ovens, DECT phones or other Wi-Fi
802.11b/g/n/ac devices in your proximity might disturb
the wireless network.
• Make sure that the firewalls in your network allow
access to the display's wireless connection.
• If the wireless network does not work properly in your
home, try the wired network installation.
Internet does not work
• If the connection to the router is OK, check the router
connection to the Internet.
The PC and Internet connection are slow
• Look in your wireless router's user manual for
information on indoor range, transfer rate and other
factors of signal quality.
• Use a high-speed (broadband) Internet connection for
your router.
DHCP
• If the connection fails, you can check the DHCP
(Dynamic Host Configuration Protocol) setting of the
router. DHCP should be switched on.
Poor quality when watching streaming video
• The image/sound quality of stream video is depending
on the original video content provided by streaming
video apps.
• To ensure the best experience of watching streaming
videos, a fast and stable network connection is essential.
The recommended network connection speed for the
streaming videos are as follows:
- Standard image quality (SD): 5 Mbps
- High image quality (HD): 10 Mbps
- 4K/Ultra HD (UHD): 25 Mbps
Bluetooth®
Unable to pair
• Make sure the device is in pairing mode. Read the user
manual of the device.
• Keep the wireless speaker as close to the display as
possible.
• Trying to pair several devices with the display at the
same time, may not work.
Bluetooth® lost connection
• Always position the wireless speaker within a range of
5 meters from the display.
Bluetooth® Audio and Video syncronisation
• Before you purchase a wireless Bluetooth® speaker,
inform yourself about its quality of Audio to Video
syncronisation, commonly called 'lip sync'. Not
all Bluetooth® devices perform correctly. Ask your dealer
for advice.
