[C] The first one I got had a real uneven screen with a "swirling vortex" of
darkness in the upper left. I returned it for this, and the replacement is MUCH
better. I think that the assemblers used their fingers a lot on the screen when
they assembled them. If you get a nice soft wide FLAT object and rub it across
the screen you can smooth this out somewhat. If you poke your finger on the
screen it will mush out the "LIQUID" in the LCD, and make the screen lighter at
that point. You can use this to your advantage to "even" out the liquid a
little bit. Mine was really spotty from the assemblers fingers, but looks MUCH
better now.
