If the test image is properly displayed, the poor picture may be caused by the source
or signal.
Store displays are all tuned to digital, HD (high definition) channels.
If you have an analogue cable/set top box, upgrade to a digital set top box. Use HDMI
or Component cables to deliver HD (high definition) picture quality.
✎
Many HD channels are up scaled from SD (Standard Definition) contents. Look
for a channel that is broadcasting true HD content.
ΠCable/Satellite subscribers: Try HD channels from the channel line up.
ΠTerrestrial/Cable Aerial connection: Try HD channels after performing an Auto
Tuning.
Adjust the Cable/Sat box video output resolution to 1080i or 720p.
The compression of video contents may cause picture distortion especially in fast
moving pictures such as sports and action movies.
A weak or bad quality signal can cause picture distortion. This is not a product issue.
Mobile phones used close to the product (within 3.3 ft) may cause noise in the picture
on analogue and digital channels.
If you're using a Component connection, make sure the component cables are
connected to the correct jacks. Incorrect or loose connections may cause colour
problems or a blank screen.
Adjust the Picture options in the product menu (go to
Brightness / Sharpness)
Adjust the Energy Saving option in the product menu (go to
Solution → Energy Saving)
