ASUS MX34VQ review: more than mere looks

Uwqhd-resolutie at 34" va-technique convinces for a sharp price


Colour quality

We already saw that the uniformity of the ASUS MX34VQ results in some variation in the colour temperature and –deviation, but we also measure these in more detail in the middle of the panel in order to compare it with other monitors.

To start off we take a look at the coverage of the sRGB colour space. With a value of 99.1% we have nothing to complain about. 

Secondly we look at the colour temperature of white in the default setting. This is clearly too high with the MX34VQ, we end up at 7303 K. However, in the sRGB-mode it is a lot better, we measure a solid 6471 K.

We were already measuring the colour- and grayscale value deviation based on the CIE2000 norm (we used the CIE1994 norm for a long time), but with the new test method we also add in 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. 

The colour deviation of the MX34VQ is not the lowest in standard mode either, but the graph is slightly distorted because of the extremely good result of the Dell U3417W. Furthermore the result is a lot better in sRGB – below we will discuss this further.

The grayscale deviation in standard mode is 4.41 – not exceptionally high, but also not extremely good. Dell raised the bar with the U3417W. The standard deviation is average as well.


sRGB colour deviation

We do not have comparison material here, but the ASUS MX34VQ has an sRGB-mode in which it performs a lot better. The colour deviation ends up at only 1.26 based on CIE2000, the standard deviation at 0.66. The grayscale deviation is also very good at 1.31 and the standard deviation is very low here with 0.41. In this mode you can definitely work with it, even for slightly more demanding image processing.

For the gamma we see that the average is decent in the standard mode, but looking at the details we can find some errors. There is a blue cast because of the dominance of blue. On the other hand, we see a solid curve and very neutral white balance in the sRGB mode (second picture).
