Picture Quality
•
First of all, please perform the

Picture Test
) If the test image is properly displayed, the poor
picture may caused by the source or signal.
The TV image does not look as good as it did in the store.
•
If you have an analogue cable box or satellite box, upgrade to a digital cable box or satellite box. Use HDMI
or Component cables to deliver HD (high definition) picture quality.
•
Cable/Satellite subscribers: Try digital stations from the channel line up.
•
Aerial connection: Try HD stations after performing Auto tuning.
•
Many HD channels are up scaled from SD (Standard Definition) contents.
•
Adjust the cable box or satellite box video output resolution to 1080i or 720p.
•
Make sure you are watching the TV at the minimum recommended distance based on the size and definition
of the signal.
The picture is distorted: macro block, small block, dots, pixelisation error.
•
Compression of video contents may cause picture distortion especially in fast moving pictures such as
sports and action movies.
•
Low signal level or bad quality can cause picture distortion. This is not a TV issue.
•
Mobile phones used close to the TV (cca up to 1m) may cause noise in picture on analogue and digital TV.
Colour is wrong or missing.
•
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.
