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.

Feedback NEC Display Solutions welcomes your feedback on MultiProfiler. Please visit the NEC DISPLAY SOLUTIONS MultiProfiler support page and give us your comments and feedback via the feedback form. 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.
PAGE 3
On some systems this command may be used sudo /sbin/udevtrigger trigger Or sudo udevadm control -–reload-rules 4. Select the appropriate version “BUILD_A” or “BUILD_B” as detailed earlier in this document. From a terminal widow, change to either the “BUILD_A” or “BUILD_B” directory where the application files are located. Verify that the required system libraries exist for MultiProfiler by using the “ldd” command. 1) Enter ldd MultiProfiler and look for any “not found” errors.
PAGE 4
Running MultiProfiler After communications with the display has been verified and any necessary libraries have been installed, run the MultiProfiler application from the terminal window using: ./MultiProfiler Note: Do not run MultiProfiler as a “sudo” because it will then create preference files with su only permissions. The splash screen will show any detected displays. Important: A message box may appear indicating no displays were detected, even though the splash screen showed that one was detected.
PAGE 5
Using MultiProfiler The functionality of MultiProfiler for Linux is identical to the Mac and Windows versions, except where noted earlier in this document. Please refer to the included MultiProfiler User’s Guide PDF document. Default UI theme The MultiProfiler application uses the Qt “cleanlooks” UI style by default.
