Explanation of Monitor Testing: The Methods We Utilize for Evaluating PC Displays
In the world of gaming and high dynamic range (HDR) monitors, factors like contrast and panel speed might take centre stage in a purchase decision. However, for photographers, it's all about color accuracy and gamut volume.
When it comes to grayscale accuracy, a crucial aspect for both gamers and photographers, the tests conducted by experts like Tom's Hardware follow a standardised approach. The grayscale is measured against a 6500 Kelvins (D65) standard for both Standard Dynamic Range (SDR) and HDR signals. For HDR monitors, the DCI-P3 spec is used as the standard for color measurement.
The tests involve measuring the Electro-Optical Transfer Function (EOTF), which is the HDR version of gamma, and plots the amount of light at each brightness level on a curve. In the EOTF chart, the ideal scenario is for the white and yellow lines to overlap, indicating perfect grayscale accuracy. If the white line falls below the yellow, it suggests that the light level is darker than the standard. Conversely, if the white line exceeds the yellow, it indicates a visible error in grayscale accuracy, with any brightness level above 3dE being particularly noticeable.
The gamut chart measures color saturation and hue for all primary and secondary colours at levels of 20%, 40%, 60%, 80%, and 100%. For HDR monitors, Calman, a special workflow designed for HDR10 displays, measures grayscale in 5% brightness increments, the EOTF curve, and color saturation tracking for the DCI-P3 and BT.2020 color gamuts.
It's important to note that these tests do not necessarily indicate the impact on panel speed, input lag, viewing angles, or contrast. For a comprehensive understanding and to make an informed decision, it's recommended to read the PC monitor buying guide.
In conclusion, understanding the intricacies of HDR monitor testing, particularly grayscale accuracy, can help consumers make more informed decisions when purchasing their next monitor. Whether you're a gamer or a photographer, ensuring your monitor meets the necessary color standards can significantly enhance your visual experience.
