ColourSpace Integration

ASUS monitor calibration is controlled via the Hardware Options menu, accessed via the Profiling window.

Initial Setup

• If required, make sure the correct drivers are installed
  (If necessary, verify via Windows Device Manager)
• Connect the ASUS monitor to the ColourSpace laptop via a USB connection, as well as a direct video connection with valid signal, and start ColourSpace
  (Due to present ASUS software issues, some monitor models may require Admin Privileges for ColourSpace to connect)
• Set the desired set-up options via the Settings menu, as required
• Open a ColourSpace Profiling window, select Hardware Options, and select ASUS from the Hardware drop-down list
• Select Connect
• From the ASUS Options, select the desired User Preset for calibration
  (Depending on the monitor model there may be 2x or 3x User Slots, definable for SDR or HDR calibration)
• To make sure there is no existing calibration data active within the selected Profile/Load/LUT/Slot, and associated colour space selection, etc., select Unity Bypass from the Select LUT option, and press Upload
  (When Unity Bypass is used with Upload all available Load options are reset - not just the selected LUT choice)
• Selecting a HDR slot, and Uploading Unity Bypass, will force the monitor into High Brightness mode for HDR calibration
  (To reach peak brightness for HDR Contrast may have to be manually be set to 80, and Brightness to 100)
• Using Calibration Patches select the desired patch option to use for profiling
  (The only option for the ASUS iTPG is full-frame)

Before proceeding further, peak luma levels for the desired standard - SDR or HDR - should be set via the monitor's OSD Brightness control, using Manual Measure with a 100% white patch.

Potentially, when Unity Bypass data is Uploaded all monitor settings will be nullified. Should it be desired that different LUTs and other settings remain as defined, upload a the Default Unity LUT, which uploads just the LUT, and does not reset any additional settings. Set necessary settings, such as Brightness/Contrast/Black-Level, before any LUT Upload.

Profiling Operation

To profile the ASUS monitor with ColourSpace navigate to the desired profiling mode - Manual Measure or Display Characterisation.

If using the iTPG, the screen of the ASUS monitor will mimic the colour displayed within ColourSpace.

As soon as a Calibration Patches selection is made the ASUS monitor will show the patch colour as defined within the ColourSpace Manual Measure menu.
The desired Peak Brightness should be set via the monitor's on-screen GUI.

Profiling can then be performed as normal, using the probe connected to ColourSpace, and with the ASUS screen displaying the required patches.

Note: The iTPG is not 100% bit-accurate, so the use of an external TPG is recommended.
Additionally, the iTPG and uploaded LUTs will not work correctly if the monitor is in YCbCr mode - it must be set to RGB.

• Open a second ColourSpace Profiling window, select Hardware Options, and select the required TPG from the Hardware drop-down list
  (Refer to the relevant TPG User Guide for further operational information)
  Note: The keyboard 'O' key can be used within the Hardware and Manual Measure menus to quickly Disable/Enable the TPG
• The probe must be connected to the same Profiling Window as the TPG

Any patch generator can be used for SDR profiling, including direct HDMI/DVI/DisplayPort connection from the ColourSpace laptop, with HDMI to SDI converter if required. For HDR/HLG/Dolby Vision, if applicable, correct metadata may be required within the video signal, requiring a dedicate TPG or metadata injector, unless the display can be manually forced into the required input format.

(If the ASUS monitor model has a Dynamic Dimming backlight, Extra Delay will be needed for HDR calibration - and potentially SDR - to allow the screen time to settle between readings. To see the impact of Dynamic Dimming select the flashing Brightness Test Pattern, especially with HDR.)

With select ASUS monitors, from the Probes Options menu it is possible to select the internal ASUS Probe from the available probes list. ColourSpace will then use the internal probe for patch measurements.

LUT Upload

After profiling, a Calibration LUT can be generated as normal within ColourSpace LUT Tools, and saved into the library.

With the LUT still held within ColourSpace navigate back to the Hardware Options menu, and select the desired LUT from within the Select LUT options, and Upload.

There are three LUT upload options within the monitor, with the 1D + 3D combination being the normal configuration to use for monitor calibration, with the post 1D LUT left empty.

• 1D + 3D (1D pre + 3D)
• 3D only
• 1D pre only
• 1D post only

The post 1D LUT can be used to pre-set a monitor's greyscale and/or gamma as a first pass, and then the monitor can be re-profiled with the post 1D LUT active, and the 1D + 3D LUT generated from the second profile pass uploaded for the final gamut calibration.

The pre 1D LUT can also be generated independently from the 3D LUT, with both being uploaded separately, with the 1D LUT acting as an input, or shaper, LUT for the 3D LUT. As with any 1D +3D LUT combination, the 3D LUT has to be generated and uploaded first, and the display re-profiled with the 3D LUT active, to enable a 1D LUT to be generated and uploaded independently.

LUT Order Issues

When uploading LUTs into later ASUS models, the upload will overwrite the User Slot within the on-screen GUI with the name of the LUT being uploaded.
