Thats really interesting. I don't have a 600, but a 1451 i; I tried your
test and I don't get that.

Not knowig the differences in the 600's TFT display, I will ventrure to say
that you have a hardware problem, where the column addressing logic has a
problem, for extreme edge conditions.

Wether this is common to all displays I can't say, but I'll bet not. I
think you have what would be condidered a slight defect. Only, if it isn't
addressing some pixels right, thats a different situation from single bad
pixels, so perhaps they'll change it out (and threaten to charge you $1000).

If you make the entire screen white, what do those pixels look like? Can
you describle again where they are? Using compass notation (N, E, W S) might
make it easier for dimwits like me to understand. ;-)
