Fine grid over the whole screen with LG screen? (especially grey areas)

[enigma2k]

First off, I know that this is how LCD screens work, but I have never seen such a visible grid on my 2010 MBA 13".

This grid is especially visible in the dark grey areas (e.g. The part where the tabs are in Safari) and when you hover with your eyes over it.

I can see this effect on 2 2011 MBA 13" with a LG screen. Unfortunately I have no Samsung to test it, but I know my 2010 MBA did not have this problem.

no one else noticed this?

I notice the difference from the Air and Pro, the Air has more of a semi matte look.

There are a few grey test patterns here, do you see it in any of those?

Yes I can see it in them too, especially the grey colors.

I can see it on my 13, I don't really notice it when I'm at the normal viewing distance.
