TagB Date & Time
Use the SCREEN SAVER to reduce the risk of image persistence.
MOTION (Default OFF): Screen image moves periodically in 4 directions in order to
reduce the risk of image retention.
Timing for MOTION can be set so the screen image moves in intervals from every 10 to
900 seconds. Timing is set in 10-second increments.
OPTION (Default REDUCED): There are two optional selections.
REDUCED: Screen image is reduced to 95% size and is moved periodically in 4
directions. Screen may appear slightly less sharp than normal. The full image appears on
the display.
FULL: Screen image is set to FULL and is moved periodically in 4 directions. Screen
image goes outside of the display area in the direction that it shifts so that a portion of the
image may appear to be cut off.
GAMMA (Default OFF): When OFF, the GAMMA selection that the display uses is the
same as the GAMMA selection in Tag5 (page 20).
When ON is selected, the GAMMA curve (except PROGRAMMABLE) becomes narrow,
reducing the contrast and cutting down the risk of image retention.
NOTE: SCREEN SAVER does not function when the TILE MATRIX function is enabled.
Video Band Width (Analog input only): It is used when the unnecessary noise from
computer appears on a screen. It is strong ineffective, so that a number becomes small.
Press "Left" or "Right" to select.
Sync Threshold (Analog input only): Adjusts the slice level of a synchronization signal.
Press "SELECT" to move the adjustment menu. Adjusts the sensitivity of the separate or
composite input signals.
Try this option if the FINE adjustment does not successfully eliminate the noise.
SOG Threshold (Analog input only): Adjusts the sensitivity of the Sync On Green input
signals. Adjusts the slice level when separating synchronization from sync On Green
signal input. Press "Left" or "Right" to select.
Clamp Position: Operating your monitor at a non-standard timing may cause images to
appear darker than normal or have colour distortion. Use of the Clamp Position control will
adjust images to their normal state.
Tile Matrix demonstrates multiple screens. This feature provides a single large screen
using up to 25 monitors. It will be able to divide up to 5 each H and V.
This requires you to feed the PC output into each of the monitors through a distributor.
ENABLE: Select "ON", the monitor will expand the selected position.
H MONITOR: Select number of horizontal divide.
V MONITOR: Select number of vertical divide.
MONITOR No: Select a position to expand the screen.
TILE COMP: Works in tandem with Tile Matrix to compensate for the width of the tile
bezels in order to accurately display the image.
