Pixelink 20” Rack Mount Series Display Operating Instructions Manual page 12

ISM (Image Sticking Minimization) is the method used to avoid long term image
retention in LCD and Plasma displays. While LCD displays are not as susceptible to
image retention as older Plasma displays, if the image will be static for long periods of
time, such as several months or longer, it is recommended to use either the Orbit or White
ISM options. Press the LEFT or RIGHT buttons to switch between Normal, Orbit and
White.
Press the LEFT or RIGHT buttons to turn the SET ID feature On or Off.
