We always assess the colour quality of monitors on a number of different aspects. First of all, we look at the coverage of the native colour space of the Philips Momentum 436M6VBPAB, which is largely similar to that of the dci-p3 standard.
We see a coverage of 97.6%, which is an excellent result. Some of the monitors in the graph below achieve even higher coverage of their native color space, but with only one exception these are sRGB and therefore a lot smaller. The exception is the iiyama X4071UHSU, which also covers a wider color space - just shy of 90% of dci-p3.
The second thing we look at is the colour temperature of white at the default setting. This is an acceptable 6396 K, which is only a small distance from the neutral 6500 K that we consider desirable.
Colour- and grey deviation
We measure the colour- and grayscale value deviation based on the CIE2000 norm, and also include the standard deviation. Simply put this gives an indication of the amount at which the sub-measurements that the average deviations are based on, deviate from the average measurement. Aside from that the averages are now based on a bigger number of sub-measurements. These can be found with the screenshots for every tested product. There you can also find the so-called saturation sweeps, that show to what extent the head- and support colours, meaning RGB and CMY, deviate from the desired values in a continuum.
With an average colour deviation of 2.64, the Philips 436M6 is just below the critical threshold of 3, above which the human eye can see deviations. In the colour checker test, in which grey values are also taken into account, the result is 3.01 – if we round that number down it is still good.

The grey deviation is indeed somewhat higher than we would like, with a value of 4.38. From the top 5 in this chart it is the worst performing model, the two other Philips monitors are a bit better tuned.

As can be seen above, the results in sRGB mode are not significantly better. The gamma curve is slightly different, but the brightness is fixed in this mode and it cannot be changed. Since the screen produces 468 cd/m² in this mode, we would recommend against using this mode at all.
By default, the gamma is on the low side, but that is better than it being too high. The deviation of 0.2 is just within the limit of what we consider acceptable.
