That's probably a dead pixel yeah. If you got something as a dead pixel insurance you can send ur screen back, but that's not always possible. Think it's best to call ur store or supplier if there is any possibility in getting a new one.

Most places have a certian number of dead pixels required before they'll accept a return. Normally about 8.
None of my TFT have ever had dead pixels (home, work, or otherwise).

Wait.... so when there's a blank spot its acutally a dead pixel.... lol i always thought that but then told myself i was foolish!
* Maniac puts on a a black wallpaper and looks for dead pixels
but wait, what about weird vertical lines that appear on the screen? I got that with all previous laptops i bought.... are those fixable?

quote:If you mean a "blank" spot as in a white pixel, then no, not always. It depends what kind of fault is happening, it can be any color (or no color at all for that matter). A pixel "staying the same all the time" is more correct

It is also possible that the connection between the monitor and PC is crappy and almost broken (same thing can happen on a PC when you don't plug in a monitor properly or the plug itself is broken). As last thing, it can indeed be a faulty screen too...

quote:It could "spread", yes. Depending on the kind of hardware fault. But if it is only a month old, I surely would go back to the shop with it (even after 1 pixel) and demand a new screen. This kind of hardware fault isn't meant to happen anymore in today's monitors and screens (unless you have a very old one or a very very very crappy one).

Btw, in the past (some years ago) this kind of fault happened when your screen showed an image too long on the same spot. Like showing the Start button all the time in Windows. After a while the image was burned into the monitor and different things could happen: the image was still shown even if you turned of your monitor (burned in) or some pixels went "dead" and didn't show any color anymore (burned out). For this exact reason screensavers were invented!
But now-a-days, all monitors and screens should be able to cope with images shown for a long time on the same spot, because screens are made differently now then they used to. Thus screensavers have only a cosmetic value now (or a security reason, but this was true in the past also).
btw: make sure those pixels aren't dirt/dust or something! Sounds stupid, but it could be just that. Some small dust particals can't be wipe off as easly. So first make sure it isn't that by cleaning your screen with a special product designed for wiping of screens.

It could also be some program causing the error. Does this problem occur when you're computer is booting up?
