We tested the screen of the Microsoft Surface Pro 2, which is an IPS panel of 10.6 inches with a resolution of 1920x1080 pixels. For a screen, it's important that the brightness is spread evenly in the greyscale from black to white, and that the primary colours are where they should be in terms of colour fidelity.
In the grey radient you can see that the primary colours have good gamma values individually, but are far apart. Their collective gamma value of 2.17 is too low compared to the ideal 2.2. This is due to minor drops at 10 and 90 percent white.
Gamma colour test Microsoft Surface Pro 2
The colour range is narrower than the sRGB spectrum, leading to undersaturated colours. The individual brightness of colours also isn't great with a large peak of blue and a smaller peak of magenta. In the DeltaE 94 test two colours score below the acceptable level of 5 (lower is better), but green, blue, cyan and magenta are way above. That's basically the same as the first Surface Pro, strange considering Microsoft's claims to the contrary.
Kleur schermmeting Microsoft Surface Pro 2
The colour temperature of 6431 kelvin does get close to the ideal 6500K, and that's better than the original Pro. The maximum brightness of 395 cd/m² is very good. Due to the low brightness of black the contrast is high at 940:1. A contrast of 500:1 and higher is normal.
The quality of the screen of the Surface Pro 2 varies. The gamma is good with only minor variances, but the colour range isn't great which causes colours to be undersaturated, the same as on the original Pro. The brightness and contrast are very good. For general use the screen of the Surface Pro 2 is fine, but not for colour critical work.
We test the display quality using SpectraCal CalMAN with a X-Rite i1 Display Pro colorimeter.
