The colour representation is measured in a few different aspects. We start by looking at the cover of the sRGB where we think that 95% coverage is the minimum in 2017. In this test, the results are predominantly good. Only three models are below that desired value.
The second thing we look at is the colour temperature of white in default mode. Most of the monitors score close to the desired 6500 K, but the BenQ VZ2470H and the LG 24MP58VQ-P both have too high temperature which results in the other colours looking too cold. The LG 24MP68VQ is the opposite with having too low temperature which makes the colours appear slightly glowing. The Philips 245C7QJSB scores just inside the acceptable margins.
In our tests, we measure the colour and greyscale deviation based on the CIE2000 standard, including the standard deviation. Simply put, it gives you an indication of what we base the average deviation on. Besides this, the average is based on a large amount of smaller measurements. Next, you will find screenshots for each tested product and find the so-called saturation sweeps, which show the extent to which the main and supporting colours, i.e. RGB and CMY, differ from the desired values in a continuum.
Also here, the results are mostly positive as no less than 7 models are within the acceptable margins of 3 which is where the distortion starts to become visible for the naked eye. The Philips C245C7QJSB comes close enough to that limit that we will not hold it in contempt over it. However, LG should put some time into improving their results. On an interesting note, the TN-panelled Iiyama has the best score here!
The greyscale is more difficult to keep in check but also here 7 of the monitor perform well with one more just at the limit. Here, LG gets the door slammed in their face by the competition...
You can find the individual results on the previous pages, including in sRBG mode and per product.
The average gamma is fine for almost all the models here, with none of the screens scoring too high. Looking at the curves, we can see that most of the screens also have a fairly neutral colour rendering while there is still much to discuss here. At the very least, the curve of the default deviation should be consistent instead of being all over the chart.
