Color Accuracy and Gamma

Color space and screen uniformity

We start our tests by measuring color space and screen uniformity. Uncalibrated performance means the out-of-the-box settings a monitor ships with. Calibrated performance is what results after the monitor has been put through our DataColor Spyder calibration process. Our aim (target) is to see display values at a Gamma of 2.2 with a target 6500k colour temperature and an aim of 120cd/m2 brightness. Luminance is candelas per square meter (cd/m2), also called 'nits'. By default, the screen is set up at default after a factory reset.


The monitor defaults close to DCI-P3 (wide color gamut) enabled as opposed to sRGB. While this mode is less visually striking, it accurately reflects the original colour design of a game or movie, which is typically mastered in this color space (unless playing in HDR). This mode is also advantageous for content creation, ensuring your photos or videos appear consistently on various displays. 

Our measurement brings us to DCI-P3 a staggering 98% coverage which is terrific, this range falls between DCI-P3 and BT.2020 HDR, meeting the minimum coverage requirements for DisplayHDR 1000 and UHD Premium. The color setting is not directly calibrated to a specific gamut like sRGB. The monitor comes pre-calibrated from the factory with good sRGB accuracy, defaulting to 8 bits per color out-of-the-box. The "wide gamut" options do not precisely correspond to either DCI-P3 or BT.2020, but this is not a concern for professional or prosumer monitors.


These monitors come factory-calibrated for you; we aim for a gamma of 2.2, which is also the default for the ASUS configuration.


Gamma deviation straight out of the box at factory settings was closer to 1.8 in reality, it's not an issue you can configure gamma in the menu settings. And yes this one was set at 2.2


OLED monitors are exhibiting greater color inaccuracies due to the nature of the display panel. These discrepancies are noticeable in certain situations, such as when displaying lighter skin tones that appear dull or unhealthy. While these issues are subtle enough that most users might overlook them.
