Security / Reliability
enhanced protection against dust
electronic devices are under constant attack from dust. in order to protect the
LCd panel against excess dust, special measures have been employed in its
construction.
Corner sealing design = special corner welding
double layer structure = double bezel/double groove
Screw & user hole sealing = proprietary screw fastening and sealing system
Many LCd panels on the market have a more-or-less open design. This allows dust
to penetrate into the panel which can lead to imperfections. The NeC MultiSync
LCd4020, LCd4620 and LCd5220 products are equipped with a completely
sealed panel, which guarantees perfect image quality over many years.
Failure of the backlights
NeC's public displays report back problems or failure of the backlight using
the Backlight Failure Reporting function. Particularly for larger installations,
the NaviSet
Administrator command allows a fast and easy check to see that
®
all of the displays are 100% operational.
12
Self-diagnosis over the network
using NaviSet
Administrator, NeC's displays can automatically send error
®
messages about their component parts or other monitor malfunctions using
the RS232-C standard or via ddC/Ci, for example, if the lamp or printed
circuit board is defective. Problems or failures can therefore be pinpointed
and repaired as fast as possible. This means repair times and service costs
are at the lowest possible level.
Free choice of id
®
every display can be assigned its own freely-selectable id. With multi-screen
installations, for example, this means that each display can be verified and
controlled without interfering with the operation of the others. The function (id
Mode) can also be remotely switched on and off.
