The screen cannot be displayed in full screen. A scaled SD (4:3) content file can cause black
bars on both sides of an HD channel screen.
A video with an aspect ratio different from the
product can cause black bars at the top and
bottom of the screen.
Change the screen size setting to full screen on
the product or source device.
Sound issue
There is no sound. Check the connection of the audio cable or
adjust the volume.
Check the volume.
The volume is too low. Adjust the volume.
If the volume is still low after turning it up to the
maximum level, adjust the volume on your PC
sound card or software programme.
Video is available but there is no sound. If an HDMI cable is connected, check the audio
output settings on the PC.
Go to Sound and change Speaker Select to
Internal.
If a source device is used
 Make sure the audio cable is properly
connected to the audio input port on the
product.
 Check the audio output settings for the
source device.
(For example, if an HDMI cable is
connected to the monitor, the audio
setting for the cable box may need to be
changed to HDMI.)
If a DVI-HDMI cable is used, a separate audio
cable is required.
If the product has a headphone port, make
sure nothing is connected to it.
Reconnect the power cable to the device and
then reboot the device.
