The BenQ PV270 and SW270C 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.)
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.
Note: There are presently no available user controls, such as for Brightness/Contrast, when using 3D LUTs, and so peak white level must be set via the LUT.
- Close the 'Upload' menu.
The Upload menu is located under 'File/Upload'.
The 'Options' menu is not really viable, 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 to 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)
Note: Communication with BenQ displays is rather slow... be patient, especially when uploading a real 3D LUT!
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.
After profiling a Calibration LUT can be generated as normal, using the Max Luma option to set the Peak White point. 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.
