As you know EeePad Transformer has quite a capable screen, with excellent viewing angles and good response time.
I just wrote an application to ease screen measurements, Free on market and Open Source, named Screen Test Patterns
But you might ask why its color look desaturated despite its correct contrast ratio.
I measure mine at 593:1.
All this explains when looking at the measurement graphs.
Almost every color are displayed brighter than it should, which results in washed out colors.
Red curve is also brighter than Green and Blue ones, that makes the colors looks a bit reddish.
At almost white there is some clipping, fortunately quite minor.
Average on this screen is gamma 2, which explains by itself the washed out colors (even if it's not the only factor)
That's not pure 2.2 nor fits to the sRGB model, but it's a nice detail improving the visual result IMHO.
Near white thing's are not right, there is some clipping. Means values 252, 253, 254 and 255 gives the same output. Not terrible in its amount but never welcomed.
