Someone (don't recall who) makes a disk that is supposed to help with stuck pixels by alternately activating/deactivating them. Perhaps this could help with you "iffy" pixel.
I learned of this disk from the Dell site (long ago) when I had an LCD with a few stuck pixels but ended up swapping computers out.
