SYMPToM: DISPLAY IMAGE IS NoT PRoPERLY SIzED
possible problem
Solution
Osd adjustments need to be made
adjust the vertical and horizontal size controls
through the Osd.
improper video display settings
verify system video display is set at 800 x 600
pixels (1024 x 768 pixels) and at a 60 - 75Hz re-
fresh rate.
SYMPToM: PICTURE QUALITY, IMAGE STAbILITY IS DISToRTED.
possible problem
Solution
Not working in 800 x 600 pixel resolution or 1024
x 768 pixel resolution
verify system video display is set at 800 x 600
pixels (1024 x 768 pixels).
proper cable grounding and shielding
verify the use of a proper video cable with suitable
grounding and shielding. keep the video cable
away from sources of emi and rFi.
improper video display settings
Check signal source for a proper signal.
verify system video display is set at 800 x 600
pixels (1024 x 768 pixels).
verify the display refresh rate: 60 – 75Hz.
display unit is farther than 3m (10 ft) from signal
source
single cable lengths in excess of the standard 3
m (10 ft) cable should be of high quality shielded
system input cable. Contact dse for information
on custom cables.
multiple monitors are driven from the same
signal source.
splitting the video signal divides the strength of
the signal. a video signal booster (line driver) is
recommended if installation requires more than
one display driven from a single video source.
display has incorrect or bad sync signals.
Check for proper video cable installation, or re-
place suspected faulty cable.
verify system video display is set at 800 x 600
pixels (1024 x 768 pixels) and at a 60 - 75Hz re-
fresh rate.
SYMPToM: DISPLAY hAS RoLLING “bARS” ACRoSS ThE SCREEN oR VERTICAL ShADED bARS oN
ThE IMAGE.
possible problem
Solution
system video display is not set to view at 800 x
600 pixels or 1024 x 768 pixels
verify system video display is set at 800 x 600
pixels (1024 x 768 pixels).
defective video cable
On a known good display source, confirm the
video cable is not defective.
interference from adjacent equipment
For proper grounding and shielding verify instal-
lation is with a proper video cable.
keep the cable away from sources of emi such
as electric motors, or unshielded rFi sources
such as radar and microwaves.
Horizontal size is not adjusted
in the Osd, adjust the horizontal size control.
