Backlight Control
Runco WindowWall Installation Guide 77
Backlight Control
The backlight is optimized for the LCD operation. For normal operating conditions,
the backlight can be adjusted for maximum brightness if desired. If you are operating
at higher altitudes up to 2000 meters, it is recommended that you run the backlight
at a reduced intensity. Running at maximum intensity at high altitudes can affect the
lifetime expectancy.
Note: To extend the backlight life, it is recommended that you use the lowest backlight
brightness that makes sense for your application. This will reduce power consumption, heat
output and the chances of TIR from occurring. (See "Recommended Usage" on page 5)
To open the BACKLIGHT CONTROL menu, press twice on the remote.
Note: The last two lines will only appear on the master (A1) display.
Auto Backlight On
If AUTO BACKLIGHT ON is checked, the display turns on the backlights soon after AC
power is applied. It won’t wait for a remote control or RS232 command.
This is the normal mode for applications where the displays will be on 24 hours a day.
This way, no one has to manually turn on the backlights after a power failure.
Caution: To prevent temporary image retention (TIR), is recommended that you do not
leave the Runco WindowWall on for 24 hours a day. To get the most out of your display, see
"Recommended Usage" on page 4.
If the displays normally have the backlights off for part of the day or night, do not
check this box. Otherwise a power failure at night would turn on the backlights.
Turn Backlight Off With No Source and DPMS Delay
When checked, TURN BACKLIGHT OFF WITH NO SOURCE (DPMS) causes the backlights to
turn off after the source goes absent for the length of time specified in the
DPMS
DELAY line. If this line is not checked, the backlights remain on indefinitely. To specify
an amount of time after which the source is absent that the backlights will shut off,
enter that number in the
DPMS DELAY line.
