Technical Features
Preset and user modes
When the monitor receives an input signal, it automatically
matches the signal to one of the factory preset modes stored in the
monitor’s memory to provide a high quality picture at the center
of the screen. (See Appendix for a list of the factory preset
modes.) For input signals that do not match one of the factory
preset modes, the digital Multiscan technology of this monitor
ensures that a clear picture appears on the screen for any timing in
the monitor’s frequency range (horizontal: 30 – 110 kHz, vertical:
48 – 170 Hz). If the picture is adjusted, the adjustment data is
stored as a user mode and automatically recalled whenever the
same input signal is received.

The visible lines on your screen especially when the background
screen color is light (usually white), are normal for the Trinitron
monitor. This is not a malfunction. These are shadows from the
damper wires used to stabilize the aperture grille. The aperture
grille is the essential element that makes a Trinitron picture tube
unique by allowing more light to reach the screen, resulting in a
brighter, more detailed picture.
