Troubleshooting Symptom Charts - 7
Miscellaneous
Screen jitter at
1600x1200
resolution
A slight jitter may be visible when connected to the ATI Rage 128
video card in the Power Macintosh G3 (Blue and White). If so,
refer to the Power Macintosh G3 (Blue and White) service
manual. (The customer might need to replace the video card.)
Important:
The display is not at fault and should not be replaced.
Limited Geometry and
Color controls when
display connected to
Apple video card
Due to signal dependencies not present on the VGA-style connector
of most third-party cards, you must use the VGA-to-Macintosh
adapter to connect the display to the DB-15 video connector, if the
card has one. The VGA-to-Macintosh adapter is included with the
Studio Display.
By using the VGA-to-Macintosh adapter and connecting to the DB-
15 port on the card, the additional video controls become available
for use. Be sure to connect the adapter to the card first, then
connect the display cable.
Popping sound that
may or may not be
followed by blank
screen
Note:
This problem most likely can occur within the first few
hours or days after installation. However, it is possible to hear
the popping sound or see the screen go blank for a moment anytime
during the life of the product. CRT arcing is normal and expected
on a certain percentage of CRT-type displays from all
manufacturers. An arc happens when residual particles inside the
CRT are dislodged. This usually occurs when the display has
experienced physical vibration like transportation. The arc time
is short and there is no safety hazard because the arc is contained
inside the sealed glass of the CRT. This arcing will not cause
permanent damage to the display.
1 Turn off monitor power button. Wait a few seconds, and turn
on monitor power button.
2 Shut down computer and monitor. Unplug power cord and
video/USB cables. Count to ten. Then plug in power cord and
video/USB cables. This action should remove all symptoms.

& Sound control
panel)
1 Reinstall Apple Displays Software and reboot computer.
2 Verify USB connection by using the control strip to change
resolutions.
