Most people eventually get to ignore them - it's a bit like living on a busy road and not noticing the sound of the traffic after a few days or driving your car and not having to think about changing gear.
I also have a Mitsubishi Diamond Pro 930sb and ditto all the above remarks. I can honestly say that I don't notice them at all, even on this forum's web site with its white background !! I don't see it at all on games or general graphics.
It's an excellent monitor (PCA refer to it as the best 19" CRT money can buy).
