ASUS Monitors

ColourSpace can be integrated with ASUS ProArt monitors for accurate Closed Loop display profiling and calibration.

  • ColourSpace INF/XPT/PRO/CAL/LTE
  • Closed Loop Profiling
  • 3D LUTs
  • Inbuilt TPG Operation

All future ASUS ProArt monitors will support 3D LUT calibration via ColourSpace integration.

Presently, the following ASUS ProArt models support ColourSpace integration:

  • PA32UCX-K, PA27UCX-K, PA32UCG-K, PA32UCR-K, PQ22UC, PA32DC, and PA32DCM

No other ASUS monitor presently has 3D LUT based calibration capability, and therefore has no ColourSpace integration.
Note: the PQ22UC may require a monitor firmware update for ColourSpace compatibility. Please send a Contact request for further information.

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 Preset for 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 real Bypass LUT (generated via LUT Tools/LUT Management/New), as that will only null the relevant LUTs, as selected. Alternatively, reset any necessary settings, such as Brightness/Contrast/Black-Level, after the Unity Bypass data 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.

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)
  • The probe must be connected to the same Profiling Window as the TPG

Any patch generator can be used for profiling, including direct HDMI/DVI/DisplayPort connection from the ColourSpace laptop.

(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. However, the internal ASUS probe is not very accurate, and we always recommend using a better quality external probe.

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 slots within the monitor, with the 1D + 3D combination being the normal configuration to use for monitor calibration, with the Back 1D LUT left empty.

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

The Back 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 Back 1D LUT active, and the 1D + 3D LUT generated from the second profile pass uploaded for the final gamut calibration.

The Front 1D LUT can also be generated independently from the 3D LUT, with both being uploaded independently, giving separate control over gamut and grey scale.
