The picture is distorted.

with fast moving pictures from sports programs and action movies.
A weak signal can cause picture distortions. This is not a problem with the TV.

The picture quality is low.

My Computer Won't Connect

When the TV has difficulties connecting to a PC, these steps may help resolve the problem.

The problem

Try this!

The "Mode Not Supported" 
message appears.

Set your PC’s output resolution so it matches a resolution supported by the TV.

The video is OK but there is 
no audio.

If you are using an HDMI connection, check the audio output setting on your PC.
If you are using an HDMI-to-DVI cable, a separate audio cable is required. Note that the 
HDMI-to-DVI connection is only supported by the HDMI (DVI) port and does not transmit 
audio. To listen to the computer sound, connect external speakers to the audio output 
connection of the computer.
