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

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.

2) Enter ldd cmdlineddclite and look for any “not found” errors.

3) Download and install any missing system libraries.

Display communications configuration:

MultiProfiler can communicate with the display via either USB or DDC/CI. Using DDC/CI will require a compatible graphics adapter and video drivers. It is recommended to use USB since it is easier to configure.

A communications verification tool is included called cmdlineddclite, which can be used to confirm communications with the display via both USB and DDC/CI.

Follow these steps to use this tool and verify communications with the display:

Run cmdlineddclite from the terminal window using:

./cmdlineddclite

The application should detect the display and show the model name and serial number.

If the display is not detected:

1. Verify that the model being used is supported by this version. See the list of supported models at the end of this document.

2. As su root or sudo run cmdlineddclite again using: sudo ./cmdlineddclite If it detects a display then the device access permissions are not set correctly. Verify the installation of the 55- NEC.rules file in the previous steps.

3. If the display is still not detected:

1) Verify that the USB upstream port from the display is connected to the PC.

2) Disconnect and reconnect the USB upstream port on the display.

3) Try connecting to the other USB upstream port on the display.

4. If a display is still not detected, try using DDC/CI instead of USB. Load the i2c module as su or sudo using: sudo modprobe i2c-dev If no displays are detected, then the video drivers being used may not support DDC/CI.

Note: If using DDC/CI, modprobe i2c-dev should be added to the system's startup script so that it will be loaded automatically whenever the system is restarted. This could be done for example by entering i2c-dev into the /etc/modules file.

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. In this case the relationship between the desktop and the detected displays may need to be configured in MultiProfiler. Open the "Display Configuration" dialog by clicking the display configuration button to the right of the display list, located at the bottom of the main window.

Then select the display on the list on the right for the selected display. Click "Test Monitor" to verify communications with the display. Both USB and DDC/CI connections may be listed. Choose the USB connection if available.

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. This can be overridden by using the command line to either specify another supported Qt style using the “-style” switch, or adding any “default” to the command line will use the system default UI theme.

Examples:

./MultiProfiler –style “plastique” ./MultiProfiler –style “motif” ./MultiProfiler default (Note: This may cause a crash on some systems due to an issue with Qt and some

desktop environments)
