Issues Solutions and Explanations
The picture will not display
in full screen. • HD channels will have black bars on either side of the screen when
displaying up scaled SD (4:3) contents.
• Black bars will appear on the top and bottom of the screen when
you watch movies that have aspect ratios different from your TV.
• Adjust the picture size option on your external device or change the
TV to full screen.
Image Retention (Burn In)
Issue. • To minimize the possibility of screen burn, this unit is equipped with
Pixel Shift screen burn reduction technology. Pixel Shift lets you set
the picture so it moves slightly up and down (Vertical Line) and side
to side (Horizontal Dot). The regular, slight movement of the picture
reduces screen burn in.
