BenQ Monitor User Guide

LightSpace CMS can be integrated with BenQ's PV270, SW270C, and SW321C displays for accurate display profiling and LUT generation.


BenQ Displays with 3D LUT Capability

BenQ Calibration

The BenQ PV270, SW270C, and SW321C are presently the only displays in the BenQ range with 3D LUT capability, and can therefore be calibrated via LightSpace CMS.

No other BenQ display presently has 3D LUT capability.
(LightSpace will report if a BenQ display has 3D LUT capability or not when first connected to the display.)


Initial Setup

The BenQ display can be calibrated using LightSpace CMS via a LUT upload, although the actual profiling must be performed via a an external patch generator, such as via the HDMI/DVI/DisplayPort output from the LightSpace CMS PC - see below.

  • Connect the BenQ display to the LightSpace PC via a USB connection, as well as a direct video connection (HDMI/DVI/SDI, etc), and start LightSpace CMS.
  • Navigate to File/Upload, and select the BenQ option from the 'Select the device type' drop-down window.
  • If there is no LUT active with LightSpace the NULL Cube option will be ticked and greyed-out, but is operational.
    (As no other LUT is available the ONLY option is the NULL Cube)
  • Using the 'Select Preset' option select the desired display preset to use, and Upload a Null Cube to re-set all internal settings.
    Note: Calibration1 and Calibration2 slots are the only two that can be user calibrated, and can only be accessed via the displays OSD after a Null Cube has been Uploaded into them.
  • To make sure no calibration is already active with the BenQ display select 'Upload', with the NULL Cube box ticked.
  • The 'Brightness' and 'PWM' controls available within the 'Options' menu can be used to set the displays brightness/contrast before profiling.
  • Close the 'Upload' menu.
BenQ Upload

The Upload menu is located under 'File/Upload'.

The 'Options' menu is not really viable at this time, and can realistically be ignored. The 'Brightness' and 'PWM' options it contains are better accessed via the Calibration Interface window, as they can be used interactively with Manual Measure to set peak luma.

  • Navigate to the 'Calibration Interface' menu, double click the small patch window to open the floating patch window
    (This will connect to the inbuilt patch generator within the Eizo)
  • Set 100% white, and select the 'Display Controls' option to open the BenQ Options menu
  • While taking Manual Measurements readings adjust the Brightness and/or PWM controls the set the peak luma value to the desired level
    (Note: The desired target value will depend on the accuracy of the white point colour temperature, as if inaccurate the Calibration LUT will need to reduce the final value to correct the white point colour temperature)
  • When set correctly, close the BenQ Options window, and profiling can begin

BenQ Options

Note: Communication with BenQ displays is rather slow... be patient, especially when uploading a real 3D LUT!


Null Cube

When the 'Null Cube' tick box is used, all display settings may be nullified, not just the 3D LUT. Should it be desired that display settings other than the 3D LUT remain as set, upload a real Null/Bypass 3D LUT (generated via File/New), as that will only 'null' the 3D LUT.

Although the option is labeled 'Null Cube', an actual Cube (LUT) is not necessarily loaded into the display, depending on the display's capabilities/options. A 'reset' command may be issued, rather than an actual Cube file uploaded.


Calibration Operation

As BenQ displays do not have suitable in-built patch generation an external Patch Generator must be used, such as via a direct HDMI/DVI/DisplayPort connection from the LightSpace laptop/PC, using the BenQ display in extended desktop mode.
(See Direct HDMI for Display Profiling for further info - this is important to read before starting profiling!)

Profiling can then be performed as normal, using the probe connected to LightSpace, with the extended desktop displaying the patches via the normal LightSpace patch window.

Extended Desktop, with the left hand side being the LightSpace Laptop/PC, and the right hand side the display being profiled.

If using a hardware patch generator, follow the User Guide for that device, such as LightSpace Connect, or the DVDO AVLab, etc.


LUT Upload

After profiling a Calibration LUT can be generated as normal. With the LUT held within LightSpace navigate back to the 'Upload' menu, and with the 'NULL Cube' tick box un-ticked, the present LUT displayed within LightSpace can be 'Uploaded' to the BenQ display. The location to upload to is selected via the 'Select Preset' option, as described above.
