just as the title says, i have a reacurring blue stuck pixel. Its on a g4 imac 15 inch display. Anytime i reset or put it to sleep, and then turn it on, it seems to come back. I have a few of those flashing videos which work, but then like i said, it comes back after a restart. Could it just be that it needs to warm up a bit to display correctly?? i just dont want it to lead to a dead pixel. im not really sure how these things operate, so any info would be great! thanks!
