First Checklist
The AppleVision 1710AV/1710 Display is not
compatible with all computers.
This display works with both Macintosh and IBM PC-compatible
computers. A video card may need to be installed to use this display
with some computers. For more information, see the computer
manual.
The display is preadjusted to work with any computer that has the
following timing ranges:
• Horizontal scan rate of 30-80 kHz
• Vertical refresh rate of 50-120 Hz
For best display performance, operate the display in one of the
standard Macintosh screen resolutions listed in the Specifications
chapter in this manual.
The CRT raster will not always resemble a
perfect rectangle.
CRT tolerances allow for some distortion. Additional distortion can
be caused by magnetized metal objects (desks, file cabinets, etc.).
Move the unit to a different location if you notice raster bowing or
bent raster edges.
Jitter, faint lines, or screen movement can be
caused by external interference such as
electronic devices and fluorescent lights
.
Fluorescent lights, other monitors, or electronic appliances such
as coffee makers and copy machines can cause raster distortion.
Move the unit to another room or building to help determine if
external interference is the source of the problem.
Note: If the raster has shifted up/down or right/left only, adjust
it using the user controls. However, keep in mind that if you then
move the monitor you may need to readjust the centering controls.
If the display changes (for better or worse) when you move it to
another location, the environment is the source of the problem.
Relocate the monitor or move the distortion-causing object.
Important: Many AppleVision 1710AV and 1710 display modules
returned for repair are found to be fully operational. Read this
checklist before you return a module, and prevent needless module
replacement and unnecessary time delays.
