RECOMMENDED RESOLUTION
If the picture does not fill the screen to the edges or if the

resolution to the figures shown in the OSD using your
computer. If the input signal matches one of this monitor's
factory preset modes, the resolution and refresh rate of the
current input signal are displayed.
FLICKER
If the picture is flickering, adjust the refresh rate to figures
shown in the OSD. If the input signal matches one of this
monitor's factory preset modes, the refresh rate of the
current input signal is displayed.
THIN HORIZONTAL LINE
The lines that appear on your screen are damper wires. See

adjusting the picture's geometry. Press the / button to
jump directly to the GEOMETRY OSD.
OUT OF FOCUS
The picture may seem to be out of focus when the red and
blue color signals are not aligned properly, causing red or
blue shadows to appear around letters and lines. Try

disappear. Press the / button to jump directly to the
CONVERGENCE OSD. When the CONVERGENCE OSD is
displayed, the contrast, brightness, and moire adjustment
settings are automatically reset for all input signals.
DISCOLORATION
If the picture's color appears abnormal in certain areas of
the screen, first check for any loose signal cables. After you
have checked the cables, try degaussing (demagnetizing)
the screen manually. Press the / button to jump directly to
the OPTION OSD, then select (DEGAUSS).
