Software to fix 'Dead-Pixels' by _Humphreys on 12-30-2006 at 10:13 PM
I have recently discovered software that apparently fixes dead-pixels on LCD monitors... Has anyone used anything like this before, and does it work?
If not has anyone managed to get rid of dead-pixels by the cloth-pressure method?

I may be being stupid, but how the hell can software fix dead-pixels?

I thought it wasn't true either, although according to some sources if you filcker parts of your screen (were the dead-pixels are located) so many times a second you can get rid of them.

I dont think it would repair a dead pixel, its in the monitor its self, hasnt got anything to do with the computer :/
EDIT: i want a link, i can try it on my dads computer
RE: Software to fix 'Dead-Pixels' by _Humphreys on 12-30-2006 at 10:21 PM
I found this info from this site, if you check out the external links that's where the software is.

Sounds dodgy, i'm not sure if it'd work.
although, it might be plausible 
* vaccination would like to know what happens, dazzy.

There is a major difference between a dead pixel and a pixel which is 'stuck' in a certain state.
EDIT: and if you read that site:
quote:It states the same....
These instructions will fix "stuck" pixels, not "dead" ones. Dead pixels appear black while stuck pixels can be one constant color like red, blue or green.

I thought that by the title of the article and then read to see 'If your LCD screen has a stuck or dead pixel' so i thought it worked for both.
obviously not though =/
but i should have read it all the first time
*slaps self*
RE: Software to fix 'Dead-Pixels' by _Humphreys on 12-30-2006 at 11:03 PM
Although the program is called undead pixels. 
Not to mention the site starts with this paragraph:
"If your LCD screen has a stuck or dead pixel (a point on the screen that is always lit or always dark) it is usually due to a transistor malfunction or uneven distribution of liquid in the liquid crystal display (TFT LCD). This can often be fixed."
I must of had some stuck pixels anyway since some have disappeared.

FFS,
They are exagurating.
To the point; If the pixel is dead t cannot be revived.
If the pixel is however just "stuck" then yes the programs works in that sense.
So for all you know yours could be stuck and not dead so it's worth a shot

Quite.
Remember to scan the file though, it may be a scam/virus/et cetera.

i demand you to send me this program that scans a file to see if its a scam!
RE: Software to fix 'Dead-Pixels' by John Anderton on 12-31-2006 at 09:22 AM
I have a lit pixel on my lcd. No dead pixels though. Mine is jsut while all the time 
RE: Software to fix 'Dead-Pixels' by Nathan on 12-31-2006 at 12:03 PM
I think it might be stuck one "white" so the program might work
RE: Software to fix 'Dead-Pixels' by andrewdodd13 on 12-31-2006 at 12:09 PM
I actually I had a "stuck" red pixel near the top-middle of my monitor - only after about 3 days of having it! However, this was as I was starting an old Dx 3.1 game (Dungeon Keeper) which ran the intro in 320x240 mode, when it switch 640x480 mode, the stuck pixel was gone. And it isn't there anymore when I play the game.
So... I would assume you don't actually need an extra piece of software to fix "stuck" pixels...
What's the cloth-pressure thing, btw?

When you rub over the surface of your LCD, you will notice it changes color. Doing this very extremely forcefully into one point (ram a pen into it
) can damage the crystals, doing it with normal pressure (eg: slightly more pressure than whiping it clean) with a cloth or something can revive "stuck" crystals.

another benefit of using CRT monitors.

RE: Software to fix 'Dead-Pixels' by CookieRevised on 12-31-2006 at 07:57 PM
CRT's have useually far smaller refresh rates than LCDs. But this isn't the most imporant thing, the important thing is the response time, which is very high on LCDs (not so high anymore with state of the art ones, but still higher). And LCDs also have a far bigger lag/ghosting.
Colour management depends on make and model, and neither LCDs or CRTs is 'best' at this. Same with image shapes.
Also something very important is the contrast ratio, which is in general much higher on CRTs. LCDs are softer and more than often the black is actually grey because of the way LCDs work.
LCDs have far more chances of dead pixels than CRTs. In fact, with LCDs it is normal to have dead pixels and this is also calculated into the quality control before they are sold. Although now some brands have a "zero defective pixel" guarentee, but certainly not all.
LCDs can have more problems in displaying stuff in other resolutions than their own standard resolution and may produce slightly distored images, colors or artifacts.
LCDs have a far less viewing angle (though this can be a benefit, depends on your POV - also literally -)
Older models put more strain on the eyes because of flickering (you may not notice it, but it does).
The only benefit LCDs have over CRTs is the low power consumption and low heat production and the small space they require.
RE: Software to fix 'Dead-Pixels' by NiteMare on 12-31-2006 at 08:20 PM
holy hell, it worked, i just unstuck a green pixel using the "undead pixels" program, and applying moderate pressure to the pixel with a cloth, its gone now

commenting on the LCD post at the end of page 2 your parents ever told you not to sit so close to the t.v?
crt screens work on the same concept and damage your eyes if you sit to close or long periods of time LCDs don't damage your eyes.

That is, they damage your eyes just as much or as little as a CRTs.
There are more forms of eye damage than radiation.
In fact, years ago, CRTs already were made with a extremely low radiation. And if you use a CRT properly (thus not sit with your noose against the screen), your eyes will not be damaged at all by radiation.
In those same years ago, LCDs damaged your eyes a lot, because the backlight used worked very slowly and this caused flickering (you wouldn't see the flickering, but your eyes will notice it). And thus this put a lot of strain on your eyes, no matter how far you were from the screen.
Now, CRTs have evolved even more and produce as good as no radiation anymore, even with your noose at 5cm of the screen, whereas there are still LCDs which flicker.
In general CRTs have still a more 'stable' picture. Not to mention the more ghosting and the slower response time which LCDs always will have compared to CRTs of the same age.
---------------------------------------------------------------------------
PS: manufacters of LCDs use a different calculation for response times than CRTs manufacters, this to trick the buyer into believing that LCDs are almost as fast, if not faster, than CRTs.
To make matters worse, there are even among LCD manufactures differences in how they calculate the response time... On top of that, if it isn't already chaotic enough, they quite often give the fastest response time measured with overdrive (which on its turn often produces artifacts or ghosting on the screen). Bottom line: response time says nothing... It is as accurate as saying that processor A is faster than processor B just by comparing the GHz.
If you compare all the relevant and proper timings in a fair way and taking in account the amount of the display updated, you'll see that CRTs are still much faster.
So, some people say LCDs have a lower response time, but it doesn't say anything about the total response time needed to update the complete picture. CRTs update the screen in one go, LCDs not. Also a LCD will always have an input lag, CRTs not. This again adds to the total time needed to update the complete picture. And this input lag is almost never given or added to the response time (which is already inaccurate) in the specs, let alone in advertisements.
If you compare everything properly, LCDs are not better than CRTs at all, and certainly not speed-wise.
EDIT: and just found this which lists the most pros and cons of both: http://bravotech.us/info/crt-lcd.htm

as long as mum doesn't know that it's alright
RE: Software to fix 'Dead-Pixels' by joemailey on 01-02-2007 at 01:09 PM
yup i gotta say it,
Cookie's replys r jus awesome sometimes lol
To backup this alot of gamers tend to stay with CRT's.
or they buy the really really expensive TFT's/LCD's
that come as close as possible to CRT's.
Crt's our generally better for gaming but there huge so i stopped using mine
