About MultiProfiler

MultiProfiler is designed as a companion to NEC MultiSync PA and new P Series monitors. It provides complete control over the powerful and sophisticated technology in these models in an easy-to-use application.

NEC MultiSync PA Series monitors feature a custom-designed color processor called the SpectraView Engine. This sophisticated processor, combined with internal luminance, temperature and time monitoring of the monitor, and individual characterization and calibration of each unit during production, results in an unparalleled level of color control, accuracy and stability.

The wide color gamut and high-contrast LCD panel used on the monitor, coupled with the SpectraView Engine, provide the utmost in versatility such as the ability to accurately emulate colorspaces like AdobeRGB and sRGB.

MultiProfiler uses a two-way communications link with the display monitor to perform adjustments. Two different methods of communications are possible:

1. DDC/CI (Display Data Channel - Command Interface) - Communicates via the video graphics adapter and normal video cable. No extra cables are necessary. Support is required in the video graphics display driver in order to provide this functionality. This communications link is an industry standard developed by VESA (Video Electronics Standards Association).

2. USB (Universal Serial Bus) - Communicates with the display via a USB connection from the host PC. A USB cable must be connected between the host PC and one of the upstream USB ports on the display. The display will also function as a USB hub.

System Requirements:

• PC with 64 bit Ubuntu Linux operating system v10.04 or higher. Other variants such as RedHat, CentOS, Linux Mint, and SUSE Linux should also work but may need certain system libraries to be installed and the configuration steps may be different from those described in this document. 32 bit versions of Linux are not supported.

• Supported NEC display(s) – see supported model list at the end of this document.

• Both DDC/CI and USB communications to the display are supported. USB is the preferred connection.

o For using DDC/CI communications: Nvidia video card with Nvidia proprietary video drivers installed.

Other video cards/chipsets may also work. ATI cards are currently not supported.

o For using USB communications: One spare USB port on the PC connected to one of the USB

upstream inputs on the display.

Differences between the Linux version and Mac / Windows versions

The Linux version has the following difference from the Mac and Windows versions:

1. It is not possible to generate a 3D LUT based on a printer ICC profile.

Installation and configuration:

Installation and configuration consists of these main steps:

Two differently compiled versions of MultiProfiler are provided for use with different Linux versions, “BUILD_A” and “BUILD_B”. Select the most appropriate version for the system being used.

Linux compatibility:

1. Set USB device permissions

2. Verify system libraries

3. Configure display communications

System library requirements:

The following steps describe the installation and configuration steps for standard installations of Ubuntu 10.04 through

13.10. Different Linux versions may require these steps to be modified.

Note: command sequences entered into a terminal window are shown highlighted.

1. Extract the files from the archive.

2. Open a terminal window (CRTL+ALT+T), and cd to the NEC_MultiProfiler_x64 folder.

3. Set the device permissions to allow communications access to the display via USB and DDC/CI from a user account.

1) As su root or sudo, copy the 55-NEC.rules file to /etc/udev/rules.d/

sudo cp "55-NEC.rules" "/etc/udev/rules.d"

Important: On Ubuntu 13.04 and higher, the rules directory has been changed to /lib/udev/rules.d/ so use

sudo cp "55-NEC.rules" "/lib/udev/rules.d"

2) The device permissions need to be reloaded by either:

a) Disconnecting and reconnecting the USB cable to the display.

b) As su root or sudo, run /sbin/udevadm trigger to load the changes

sudo /sbin/udevadm trigger
