I spotted a dead pixel color black on my screen, then about 2 months after I change my graphics card, the pixel death was still there.And now that the beginning of this week, I noticed that the pixel is returned to normal .....
My question? How is this possible?
The dead or missing pixels do in any case the graphics card but just the screen. There are so many pixels on a screen nowadays that the likelihood of a contact to be failing are quite large.
Some displays are guaranteed 0 defective pixels, others have no guarantee therefore have to live with.
The difference between a dead pixel and defective?
A dead pixel is definitely dead what is described in one or more of the three alpha channels not responding.
A defective pixel can be revived by software that can be found on the net (I never had a result), their objective is to scan a maximum of colors in a minimum time (multicolor strobe type).
But what I find strange is just the fact that without using one of these programs "miracle" he revived it alone without speak voluntarily.
