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 with calibration is to be at a Gamma of 2.2 with a target 6500k color temperature and a 120cd/m2 brightness. Luminance is candelas per square meter (cd/m2), also described as 'nits'.

The Asus RoG Swift is a truly proper HDR panel and meets the requirement of a larger color space. By default, the screen is in Racing mode, but it does offer a dedicated sRGB mode. Most software, however, can not deal with a wide gamut range, which makes colors appear very saturated. We measured the screen in both modes for color space testing and show, where relevant, both results.

Gamma

These monitors come factory calibrated for you, we aim for a gamma of 2.2

Gamma uncalibrated was 2.1, there is an allowance deviation of 10%, so that is 'okay'. This is the monitor untouched out of the box. Of course, you are free to alter and tweak anything to your liking yourself as the monitor has selectable gamma modes. 

From a practical perspective, the average human eye cannot detect any color differences with a Delta-E value of 3 or less and an exceptionally trained and sensitive human eye will only be able to perceive color differences with a Delta-E of 1 or above. The monitor is excellent at a △E<1 average.
