First Checklist/ - 3

Vertical refresh rate of 47-120 hertz

 

For more information on what computers or video cards are compatible with the 1705 display, see the Specifications chapter.

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.

Move the unit to another room or building to help determine if external interference is the source of the problem.
