Stuck Pixel..


J

JD

I just purchased a 22 inch wide screen LG LCD monitor and it has one
stuck pixel for lack of a better description. It's a little green dot
right at the edge of the monitor.

I've done a lot of research about this and I've applied a variety of
fixes including bumping and rubbing the pixel and I've run a little
video that alters between all the colors to try and unstick the pixel.

Nothing has worked. I ran the color video for two hours.

My question is what can I use to cover this one pixel but not damage the
surface of the monitor? I tried a Sharpie but it didn't stick. I was
able to wipe it off. Since the pixel is right at the edge of the screen
it would be less noticeable as a small black dot.

I can return the monitor but place where I bought it doesn't have any
more of this monitor and they can't guarantee one shipped to me won't
have the same problem. Also, they will charge me a restocking fee even
thought the monitor is defective which means I won't be buying any more
monitors from them.

The monitor is not viewed as defective unless it has several dead pixels.
You have only one and consider yourself lucky. Even if you get a monitor
with no dead pixel, chances are it will develop dead pixels over time.

This is my third LCD but the first one to come out of the box with the
stuck pixel. From what I can tell, it is hard to return a monitor with
only one stuck pixel.

What I'm trying to find is some black substance to apply to the screen
to cover the one pixel. Since it's at the very edge of the screen I
could tolerate a little black dot better than the current little green dot!

Any ideas?

You could return it and get a Samsung instead. Samsung has zero dead pixel
policy. But they will still ding you for the restocking fee because it is
not really defective by LG's standards. Maybe just learn to live with it. I
had a pixel stuck on blue on an older LCD and I learned to live with it. I
only ever noticed it on a black background and even then it looked like just
a blue pin prick.

I understand what you're saying. I'm keeping the LG. Right now I have a
small piece of black electrical tape covering the one pixel because the
little green dot drives me crazy when my black screen saver is on.

My preference would be to find something to paint the one pixel with. A
sharpie didn't work so you got any ideas on what I could use to put one
little black dot on the LCD screen without screwing up the screen? An
LCD screen surface is plastic?

Don't use screen savers, the accomplish absolutely nothing. Use standby.

The black screensaver accomplishes the task I want it to do, it makes
the screen go black.

Do you think a little spot of black latex paint would harm the surface
of this LCD monitor?

Using standby (or simply turning the thing off) would accomplish
the same thing and save electricity as well, while also helping your
monitor to last a bit longer.

Outside of putting a black spot on it, no. But it would also
be pretty easily scraped off.

Under Display Properties, Screen Saver tab, when I click on the Power
button I get Power Options Properties. I see I can turn of the monitor
after a certain period of time. Is this the setting you're referring to
as "standby"? Or are you referring to System standby?

I use my computer throughout the day so I've never thought about
powering it down.

I figure latex paint is water based so it shouldn't hurt the LCD
surface? At this point, I've covered the offending pixel with a very
small piece of black electrical tape.

The very thing.
That turns off the BLU (backlight unit), and possibly other
electronics, thus reducing thermal aging. Just using a black
screen-saver doesn't usually do the same (and actually
traps a small amount of heat that would otherwise get out
through the panel as light).

Stuck pixels are by no means a certainty. I have an hp f2304
(now replaced by some other model) that appears to have
zero defects, after several years of use (although due to the
way I bought it, it could easily have been a "remanufactured"
customer return having fewer than "defective" stuck/dead/hot
pixels).

Before buying an LCD, a buyer needs to discover the
brand and reseller duff pixel policy, and decide if it would
be acceptable to get a display just short of "defective".

There's also the issue of return shipping. Not only is it costly
to send these things, the last I knew, the carriers would
not honor claims for damage in transit on LCDs.
Yeah, they'll happily take your money for extra
insurance - and you can count on never seeing it again.

That's the setting you should use. LCD's take a split second to turn
back on - a little longer for full brightness, but instantly readable.
When powered off, you're saving the backlight. When using a black
screensaver, you're leaving the backlight on, but preventing any light
from exiting the panel.

So use the setting to turn off the monitor and not put the entire system
into standby? Powering the monitor on and off is easier on it than just
leaving it on?

As long as you're not overdoing it, yes. It is far better
to shut the monitor off when it's not going to be used
for a while - say, if you won't be using it for an hour or
more - than to leave it running.

I use a shortcut on my desktop to start the black.scr file. Is there a
file on my computer will put the monitor into standby and then let me
bring it out of standby with any kind of mouse movement, etc., like the
black.scr does?

When I don't use the monitor for over an hour I do turn it off but this
is a rare occurrence. I'm using the computer all day with only short,
less than an hour, breaks. So if I was turning the monitor on and off
every 20 minutes then that would be over doing it?

You can set it up so the monitor will automatically be
powered off after a certain period of activity, under the
Power settings in the Windows Control Panel. Or you
can always simply turn the monitor off. The important
thing is that the backlight gets shut down, and that's also
the thing that takes the longest to come back up in an
LCD monitor. So either way, it doesn't matter.

Every 20 minutes, yeah, that would be a bit much - but there's
nothing at all to be gained by simply putting up a black
screen. But definitely turn the thing off overnight, or if you're
going to be away from it for an extended period.

Thanks to everyone for this rather extended discussion!
