Samsung C49HG90: decadent thoroughbred in 32:9

Extraordinary gaming monitor offers everything, except a good price per pixel ratio


Colour quality

The colour quality of the Samsung C49HG90 is judged on a few different aspects. 

For starters we take a look at the coverage of the colour space of the Samsung C49HG90. If you see the graph, you might be worried: only 91.7%?! However, we always test the monitor directly out-of-the-box and compare them with the colour space that they come closest to. With all models in the graph this is sRGB, but with this Samsung it is DCI-P3, a considerably larger colour space, that holds the middle between sRGB and AdobeRGB (and, among others, was chosen by Apple as their colour space until Rec.2020 becomes a reality). Samsung achieves this colour space because of the application of a quantum dot filter. 

We also measured in the sRGB-mode - which it has, something that is not the case for all models that we compare it to, as you can see - and we measure 99.9% here. Only blue misses a small bit of saturation. This is abundantly compensated for by the more saturated green and red, something that the human eye is considerably more sensitive to. 

The second thing that we look at is the colour temperature of white using the standard setting. With a value of 6439 K the Samsung C49HG90 is close enough to the desires 6500 K that we will not cover this further, except that it improves slightly in sRGB-mode: 6455 K. 

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. 

Starting with the colour deviation, we end up at 1.47 - a result that would make a lot of professional monitors rather jealous. Furthermore the standard deviation is also small, although Samsung is surpassed by two other models in this regard. 

The grey setting is possibly of an even higher level, with a DeltaE-fault below 1 this Samsung gaming monitor does something that other brands can only dream about doing with their monitors for the professional market. 

Standard and sRGB-mode

Below you can clearly see that the colour space in standard mode is considerably larger compared with sRGB. A requirement for HDR, which is fortunately met.

With an average gamma of 2.18 the C48HG90 has a negligibly small deviation compared with the desired value. Furthermore the standard devation of the sub measurements is the lowest out of all the models in the graph.
