data monitors and data projectors are not compatible with these resolutions and
frequencies.
Œ
Solution 3: Check the dipswitch settings to make sure the unit is putting out a sync
format that the display device can use. For most applications, the default dipswitch
settings (see page 15) will work best.
Œ
Solution 4: The RGBS or RGBHV cable may have a bad sync line. Try running the
sync through another cable.
Problem: The output image is very dark.
Œ
Solution: The horizontal position control may be set off to an extreme setting or may
be interacting poorly with the horizontal position control on the display device. Follow
the horizontal position adjustment procedure on page 15.
Problem: The local monitor looks fine but the image on the LCD projector is wavy or has
vertical bars in the picture.
Œ
Solution 1: LCD / DMD / D-ILA / Plasma Display devices work best when the sync
signal has minimum sync processing. Set the interface dipswitches to the factory default
positions (see page 15). In some cases, disabling the horizontal position control may
alleviate this problem.
Œ
Solution 2: LCD / DMD displays often have an adjustment called Phase Adjust or Fine
Phase Control. This control should be adjusted to provide the best image.
Problem: The output image is missing a color.
Œ
Solution: Possibly the RGBS or RGBHV cable is bad. Try switching connections on
the output to verify that the bad color’s cable is OK (Example: If there is no red, try
running the green output through the red cable and see if the green is displayed or not).
Problem: The output image is too green.
Œ
Solution: The dipswitch settings may be set for sync on green output and the display
device doesn’t like that format. Try changing the dipswitches to output an RGBS or
RGBHV signal (see Dipswitch Settings Section on page 15).
Problem: The horizontal position control is not working.
Œ
Solution 1: Check the dipswitch settings to see if the horizontal position control has
been disabled.
Œ
Solution 2: The input setting may be RGsB (sync on green). The horizontal position
control does not work with RGsB input signals.
Problem: The output image is doubled, with two images displayed side-by-side.
Œ
Solution: The display device may not be compatible with the horizontal scan rate of
the computer. This problem often occurs when a 31.5 KHz VGA signal is sent into an
RGB monitor that is only compatible with signals at 15.75 KHz.
