SmallHD User Guide


Updated on

Your monitor ships calibrated from the factory with a default factory LUT.  The factory white point, color space, and gamma are shown in the menu below the factory tick box. Custom calibration can be performed using a compatible calibration system to account for long-term color drift. SmallHD recommends using Calman or ColourSpace calibration systems. For guidelines on how to use Calman or ColourSpace calibration systems, click here.


  • Manual Adjustment - Manual Adjustment allows you to modify each of the monitor's individual color value, such as Gamma Shift, RGB Gain, RGB Lift (Offset), and Saturation.
  • Adjust Peak Luminance - Allows you to adjust the nit count of your monitor to improve accuracy, especially when using HDR.  NOTE: Adjusting the luminance on your monitor requires the use of a calibration probe. We recommend probes that can handle at least 2000 nits of brightness and 1:100000 contrast ratios (depending on your monitor Nit level, your probe should handle more).
  • New Calibration - Create a new Calman or Generic Calibration profile.

Calibrating Your Monitor

NOTE: Before you proceed, ensure that your monitor has been on for 45 minutes. You can run video or a test signal during this time.

1. From the Settings page, navigate to Display > Calibration and tap New Calibration.
2. Select a calibration procedure:

  • For Calman Calibration, visit this page and download the Calman Professional (Version or later)
  • For Generic Calibration, proceed to the next steps.

3. Select your calibration target (DCI P3 is recommended), then tap Accept Calibration Target on the following screen.

4. Select an Input Range. Select Legal Range or Full Range (recommended), or select Auto if you are unsure of the data range.

5. Tap Profile display to begin calibrating. Ensure your calibration probe and computer are connected and transmitting a video image to the monitor. 

If you already have a calibration LUT you would like to use, tap Other options.

6. Position your probe against the monitor’s screen according to the manufacturer’s recommendations. Tap Minimize UI to keep the menu from interfering with the calibration patches. The display is in unity bypass mode at this point. Complete the calibration profile and then tap Done to continue.

7. Generate a compatible 3D LUT with your calibration software and copy it to an SD card.  Insert the SD card into the monitor and tap Browse for LUT to find and install your new 3D LUT.

7. Measure the HDR Range (Contrast Ratio) by tapping Begin. Select Measure Dynamic Range to use the calibration probe to measure the monitor’s dynamic range and values, or select Skip to apply factory measurements.

8. From the Calibration Summary screen, use Manual Adjustment to modify the calibration profile, or A/B Compare, which allows you to compare new, old, and factory calibrations. Tap Save Calibration to save your settings.

9. Your new calibration profile will automatically be applied and listed as Custom Calibration in the Calibration settings. You can toggle between Custom Calibration and Factory Calibration at any time.
