But this doesnt look like bad pixel. More like smudge or something. Also this doesnt appear always. Sometimes is visible,sometimes not. Any ideas?

From the other angle it looks like this:

Also why sometimes i can see this and sometimes not? Any explanation? Its hard to describe. For me its not dead pixel,because from other angle it looks white. From second angle looks like black smudge. Any ideas? And sometimes when i turn on monitor that "thing" is gone,sometimes its visible. I cant understand what can it be. THanks !

If it is always in exactly the same place then it is almost certainly a screen problem - not sure exactly what. The reason you don't always see it could be that it depends on the color or brightness of the image.

Dirt is always a possibility. On one of my screens an insect used to walk around inside it. I didn't dare press the screen on it because it would have been even worse if it was permanently in one place.

Can I assume you have proved it is the screen be either trying it on another computer or by trying another monitor on yours? My guess would be a screen fault.

Always pop back and let us know the outcome - thanks

Yes its always on the same place in screen. But sometimes its not visible,sometimes yes. So exchange monitor to another example in shop? Like i said its hard to describe. Its not a dead stuck pixel for me. More like a smudge but why it is dissapearing ?

Like I said you ought to prove for certain it IS the monitor.

It probably isn't visible sometimes because it blends in with the background (I've had that sort of thing before).

Different angles, backgrounds and brightness can all change the appearance of blemishes.

At the end of the day all you need to do is prove for certain whether it is the monitor or something else. You do that by trying it on another computer or trying someone else's monitor on yours. If, as is almost certain, it is a monitor fault then it matters little why it behaves the way it does because the only way to fix it would be a replacement monitor.

Nobody repairs them these days because it is not cost effective.

My very good quality 1920 x 1200 Dell monitor eventually had
a single pixel go bad. It didn't look like your spot, but it *was*
fuzzy. It looked like the pixel had exploded and a microscopic
field of debris lay all around it. I put up with it for several months
when one day I rubbed the surface of the screen with just a little
bit of force, and the spot started going away! It only took a few
seconds and the spot was gone! I did that after reading that it
works in some cases. I didn't think there was any real hope it
would work on my seemingly exploded pixel, but it did. It was
definitely not a spot on the surface of the screen, either. I looked
at it with a 30-power microscope and the problem was clearly a
bad individual pixel, with a fuzzy colored halo around it.

On another computer -- a very old Dell laptop -- the screen has a
vertical line which becomes visible as bright blue when I power on,
then slowly disappears as the screen warms up (a minute or two),
and then begins to reappear as yellow (absence of blue) as it gets
warmer yet. The vertical line of blue pixels starts out as overbright,
and within three minutes has turned black, so that from normal
viewing distance it looks yellow on a gray or white background.
It is black on a blue background, and isn't visible at all on a red,
orange, yellow, or green background.

I know this is different from your problem, but it shows what some
of the effects can be.

Yep, there are stacks of possible manifestations. We had a TV once that had a vertical line at bottom left which went down and turned the corner producing a horizontal section too. On some pictures it stood out like a sore arm, on others you couldn't see it at all.

It is worth trying Jeff's idea about rubbing the surface, unless it is in warranty when it would be best to get it replaced.

The question on how it can vary has already been answered. Anything viewed further away looks smaller.

You need to decide whether to live with it or do something about it.

Just keep an eye out for it to return, but otherwise don't
worry about it. If it comes back, you can try again to figure
out more precisely what's causing it. Patience. You might
just forget about it entirely until the monitor fails in some
other way.

Most likely it is defective hardware (the monitor) but many faults are intermittent and not just computer kit.

Nobody can say whether it will stay away or come back again.

You just have to keep monitoring then make up your mind on the basis of how long the symptom has stayed away.

I would return it but it would have been better if you had proved for certain it was a monitor fault when it was doing it. It would be worth sending them your pictures.

It looks like a hardware fault. It certainly isn't any kind of
software fault. The only other realistic possibility is that you
are mistaken about it not being a spot of something like dried
spittle on the surface of the screen. You would be able to tell
that fairly easily by inspection, and cleaning the screen would
either make it go away permanently or make it less visible
permanently. It might appear to come and go depending on
the background color of the screen, changing incident light
on the screen, or viewing angle, but I assume you have looked
at it enough times, under enough different conditions, to rule
that out. So you seem to be left with a mysterious but minor
hardware fault which is currently not causing you any problem
at all, and may never return.

You write as if the warranty is about to expire. If your past
experience is that the spot will return, and it really bothers you
that much, then go ahead and get an RMA, knowing that if you
send it in but the people there don't find any fault which meets
their qualifications for replacement, they are likely to send it
back to you.

Unless it is extraordinarily important that the screen be perfect,
I'd wait and see if the spot returns, hope for the best, and not
worry about it.

Even if it is dirt under the screen you still can't fix it except by replacing the monitor.

I think we've repeated ourselves enough - time to make a decision.

Ah i forget.

In first day of use,
Bright little spot was only visible on light blue colours when your looking at a side angle. Not when you're looking directly at the screen. What was that?


It now is ok actually, but i am asking only. Thx

Because there is/was a monitor fault which can manifest in many ways, as already said. It might or might not return.
