device sound output to the TV’s VGA stereo input. If your HDCP video device uses
RCA audio jacks, you’ll need to obtain an audio cable with RCA plugs on one end
and a 3.5mm plug on the other.
Cannot get 1920
x 1080 from PC
VGA
The screen’s max resolution is 1920 x 1080. Your video card may not support this
resolution. Check your video card’s maximum resolution, and use that setting.
Picture is

an abnormal
sound
This might be from interference from large electrical appliances, cars, motorcycles
or uorescent lights. If the TV is close to the wall, try moving the TV to another
location to see if the problem still occurs.

screen
If you are using HDMI or a TV digital channel, use the Aspect button to switch to
16:9 format. If you are using VGA, use the computer’s video controls to adjust the

a VCR or DVD player in 480i resolution, use the Aspect button to switch to 16:9 in
order to ll up the screen. However, this feature will distort the picture.
Trouble Solutions
Picture quality is
very poor
For best image quality, view HD widescreen programs. If HD content is not
available, use a digital source (DVD or Blu-ray player, digital satellite or digital
cable box). Standard 480i TV programs will be noticeably inferior to HD quality.
Some pixels are
always displaying
the same color
SunBriteTV LCD screens are manufactured to rigorous standards to maintain
optimal viewing. However, the LCD screen may have minor defects that appear
as a small bright or dark pixel. This is common to all LCD screens used in display
and television products, and is not specic to SunBriteTV. For more information,
see SunBriteTV’s Pixel Quality Policy in this manual.
Switching a
channel or source
changes the
volume
Dierent channels and inputs sometimes have this eect because the channel
signal’s volume is pre-set.
There is noise or
trash pixels on the
screen
When your TV’s resolution is higher than the digital channel’s broadcast
resolution, the signal is up-converted to match your TV’s resolution. Up-
converting can cause this kind of eect.
Tips for high-
denition users
The TV is an ideal platform for viewing high-denition content. The best image
quality can be achieved by HDMI, YPbPr (component), then VGA. However, due
to variances in broadcast practices, it is possible that some image distortion
may occur.
Tips for letterbox
content users
Letterbox (widescreen) versions of DVD movies are most commonly formatted
for standard 4:3 TVs. The TV has the capability of expanding this content so
the entire screen is lled, at the expense of the image proportion. To use this
function, press the Aspect button on the remote control and cycle among the
available options.
The TV turns o
automatically
The TV features a power-saving mode which will automatically turn o the TV
if there is no signal provided for 15 minutes.
