Calibrate monitor colours using the TruHu app

The TruHu app is a smartphone-based monitor calibration software that is compatible with macOS Mojave and later, and iPhone SE 2nd Gen and later. It is a quick and easy way to calibrate your monitor colours, and it only takes 1-2 minutes to complete the process. Here's a step-by-step guide on how to calibrate your monitor colours using the TruHu app:

Step 1: Install the TruHu App

Download and install the TruHu app on your iPhone and desktop device. Make sure that both devices are logged into the same account for a smooth connection.

Step 2: Warm Up Your Monitor

Before calibrating, it is recommended to let your monitor warm up for a while. Modern screens stabilise quickly, so about 10 minutes should be enough. If you have an older screen, let it warm up for 20 minutes. Alternatively, you can put your screen into "sleep" mode to keep the backlight at a constant voltage, and it will stabilise in a few minutes after waking up.

Step 3: Launch TruHu and Follow the Instructions

Open the TruHu app on both your iPhone and desktop. Follow the on-screen instructions provided by the app to complete the calibration process. This will involve taking two photos with your iPhone.

Step 4: Adjust Settings as Needed

After calibration, you may need to adjust some settings on your monitor. TruHu may reduce the max blue value to achieve a warmer white point, resulting in a slightly dimmer screen. If needed, you can turn up the brightness to your desired level without affecting the calibration.

Step 5: Calibrate Regularly

The recommended calibration frequency depends on how often you use your screen. Professionals who have their screens on for about 40 hours a week should calibrate monthly. Casual users can calibrate every 3-6 months. With TruHu, you can calibrate as frequently as needed without any additional cost.

By following these steps, you can ensure that your monitor colours are accurately calibrated and maintain colour consistency across your devices.

Calibrate monitor colours using rtings.com settings

Calibrating your monitor is a great way to ensure that colours are represented accurately on your screen. While the most common and accurate method of monitor calibration involves the use of a calibration tool such as a tristimulus colorimeter, this method can be costly and inaccessible for many. However, rtings.com offers a guide to calibrating your monitor using basic test patterns, which can substantially enhance the picture quality and provide a more balanced image.

Backlight Calibration

The 'Backlight' setting, sometimes called 'Brightness', changes the amount of light your monitor outputs, making the screen appear brighter or darker. Adjusting the backlight level does not significantly alter the accuracy of your screen, so it is recommended to set it to your personal preference.

Picture Mode Calibration

The picture mode presets on your monitor can significantly impact the image settings. For most monitors, the 'Standard' or 'Custom' preset is the best option for accurate colour representation. Some monitors also offer an "sRGB" picture mode, which can enhance image accuracy, particularly on wide gamut monitors. However, this mode may lock the rest of the calibration settings, limiting customisation.

Brightness and Contrast Calibration

Brightness and contrast settings affect how the screen displays tones at different brightness levels. To calibrate brightness, use a near-black gradient test pattern and adjust the setting until the 17th step disappears, then go back one step to make it visible again. For contrast, adjust the setting until steps up to 234 show some visible detail, with the last few steps being very faint.

Sharpness Calibration

Sharpness is another important aspect of monitor calibration. While the default setting is usually fairly accurate, you can adjust it to your preference. To calibrate sharpness, set it to the max and then lower it until no strange pattern forms between the lines and shapes of the test image.

Colour Temperature Calibration

Colour temperature adjusts the overall tone of the picture, with cooler temperatures giving a blue tint and warmer temperatures yielding a yellow or orange tint. rtings.com recommends a 6500k colour temperature, equivalent to midday light, for most screen calibrations. However, you may adjust it to your preference if you find it too yellow.

White Balance Calibration

White balance refers to the balance of colours across different shades of grey. Unfortunately, it is challenging to adjust white balance settings accurately without specialised equipment. Therefore, it is recommended to keep these settings at their defaults, as incorrect adjustments can easily make the image worse.

ICC Profiles Calibration

If you use a calibration tool, your software will likely create an ICC profile, a reference table that helps your computer display content accurately on your screen. While ICC profiles are beneficial, it is not recommended to use a profile built for another monitor, even if it is the same model, as the accuracy can vary between units.

By following these steps and adjusting the relevant settings, you can calibrate your monitor using the rtings.com settings, improving the accuracy of colour representation on your screen.
