Roger Breton, 2012 December 2
Here are some useful measurements for those who would compare Microsoft Surface RT display to other displays and monitor specifications. Visually, the green appears quite like a typical green. The red seems a bit orangish, though? And the blue is a bit too bright to be useful and its CIE_y value is somewhat odd?
The white is close to D65. The gray scale tracking seems pretty good. At 147 to 0.36 cd/m2, the contrast ratio is 408. Seems plenty.
Could someone please estimate the Transfer Function from the above Luminances?
I have included measurements for :
RGB = White = 255,255,255;
G224 = Gray224 = 224, 224, 224;
G192 = Gray192 = 192,192,192;
G164 = Gray164 = 164,154,164;
G128 = Gray128 = 128,128,128;
G92 = Gray92 = 92,92,92;
G64 = Gray64 = 64,64,64;
K = Black = 0,0,0.
All measurements made normal to the screen, in full darkness, in the Photos app.
RGB target created using Adobe Illustrator.
“Active” ICC profile associated with the display is “sRGB” according to Windows Color Management Control Panel.
