LightSpace CMS integration with TVLogic displays

Eizo Calibration

At the time of writing only the following TVlogic displays can be 3D LUT calibrated via direct LightSpace CMS integration:.

Note: The XVM-245W (note the missing -N) will not work, as while it does have internal 3D LUT capability it uses a totally different approach to LUT management that is not compatible with LightSpace CMS.

All TVlogic displays with 3D LUT capability, including the XVM-245 model, can be calibrated via a LightSpace CMS generated LUT, with the LUT uploaded via TVlogc's own display control software. See the end of this page for further information.

Any other TVlogic display not listed here should be assumed to have no 3D LUT capability, and we suggest checking with TVlogic directly before any purchase is made if intending to calibrate via LightSpace CMS.


Initial Operation

Select TVlogic displays can be calibrated using LightSpace CMS via direct LUT upload, although the actual profiling must be performed via a an external patch generator, such as via direct HDMI/DVI/etc. output from the LightSpace CMS PC, as there is no inbuilt patch generator capability within any TVlogic display. See below for more information on external patch generation.

Note: Please be aware that the way TVlogic provides for display calibration is not presently as intuitive or simple as with other displays, and it is imperative that the following instructions are fully understood before attempting any user calibration - especially the danger of overwriting the factory pre-sets, for which there is no factory provided recovery method, as well as the need to pre-configure the display correctly to prevent unexpected and incorrect results.

TVlogic Upload

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

Both before and after uploading the 'Null Cube' use the Initial Display Set-up guide to verify the display's pre-calibration configuration, using the display's own manual controls. Specifically check for correct black and white settings.


Profiling & Calibration

In the following profiling workflow, as TVlogic displays do not have in-built patch generation, the direct HDMI/DVI/DisplayPort connection from the LightSpace laptop/PC will be used for patch generation during profiling, using the 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.

TVlogic Calibration

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

One key requirement is to match the Patch Generation range with the previously set display video range - Full, Limited, or LimitedEx - using the 'Patch Scale' function within the 'Options' menu.

An alternative is to use a 3rd party patch generator, such as using Resolve, Mistika, BoxIO, or IS-mini etc., again under direct control of LightSpace CMS.


LUT Upload

After profiling a Calibration LUT can be generated as normal, and 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'. The location to upload to is selected via the provided drop-down menu, as described above.

To make sure the LUT that has been uploaded is active you will need to manually select a different colour space slot, and then back to the slot the LUT was uploaded to. This is a TVlogic workflow restriction.

Repeat the process for all the required profile slots, enabling quick LUT swapping via the display OSD controls and the different colour space presets.

Note: The LUT Upload process into the TVlogic display is very slow, which is a limitation of TVlogic displays. Additionally, the USB serial connection can become unstable if powered off. You MUST wait 5 minutes with a hard power off (cable out) before turning back on. If you don't, the internal monitor USB system may not come up correctly.

WARNING: The LightSpace CMS GUI will show a warning if you attempt to upload a 3D LUT into a factory pre-set slot. If you click OK, it will be over written, and there is NO factory reset to reinstate the original LUT. You have been warned! It is possible to backup the factory preset TVlogic LUTs via TVlogic's own display management software.


Alternate Calibration

As an alternative, for any TVlogic displays with 3D LUT capability, it is possible to use the 'standard' LightSpace CMS calibration workflow, as defined in the various LightSpace CMS User Guides, and at the end of the process export the LUT in TVlogic format, and load into the display using TVlogic's own display control software.
