About NEC Display Firmware Update Tool

The NEC Display Firmware Update Tool is a utility to assist with updating the firmware in large-screen Sharp and NEC LCD displays and some models of desktop NEC LCD displays.

Main features:

Automatically locates networked Sharp and NEC display models and determines if newer firmware is available.
Details of the changes between the installed firmware and the latest version are listed.
Automatically downloads and verifies the latest firmware. Firmware can be downloaded for off-line use if needed.
For models that can be updated via LAN, the update process is almost fully automated and the progress and estimated remaining time is shown.
Up to 20 displays can be updated via LAN simultaneously. Other displays are queued until an update slot becomes available.
For models that are updated via USB, the correct firmware is copied to a USB drive and instructions on how to update are displayed.

This application always downloads the latest version of firmware for each display. If it is ever necessary to revert to an older version of firmware, it must be performed manually via a web browser.
