N Many HD channels are upscaled from SD(Standard Definition) contents. ● Adjust Cable/Sat box video output resolution to 1080i or 720p. ● Compression of video contents may cause picture distortion especially on fast moving pictures such as sports and action movies. ● Low signal level can cause picture distortion. This is not a TV problem. ● Make sure the Component cables are connected to the correct jacks. Incorrect or loose connections may cause color problems or the screen will be blank. ● Adjust Picture options in the TV menu.
