Standard, analog TV will always be noticeably inferior to HD because your digital flat panel TV has video that is many times better than old TV’s and so you can see interference and deficiencies you did not know you had.

Your LCD HDTV is manufactured using an extremely high level of precision technology, however, sometimes some pixels of your LCD HDTV may not display. Pixel defects within industry specifications are inherent to this type of product and do not constitute a defective product.

When your LCD HDTV’s digital capabilities exceed a digital broadcast signal, the signal is up-converted (increased) to match your TV’s display capabilities. Up- converting can cause noise or trash.

The TV remembers the volume level from the last time you adjusted it. If the sound level is higher or lower from another source, then the loudness will change.

The LCD HDTV is an ideal platform for viewing High Definition Content.

Best Image Quality will be achieved by the HDMI Input, then YPbPr, then RGB.
