M1330 wierd pixels

Well, I guess this isn't really dell specific, but I guess I'll ask here anyway. Just got my LCD panel replaced a few days ago and was initially happy, not noticing any dead/stuck pixels. Soon though, I noticed two bright white diffuse pixels. The weird thing is that they are most noticeable on a white background... but completely gone on a black background. So I have 2 brighter white pixels most visible on a white background. They are more diffuse and soft around the edges, but still about the size of a pixel. Kinda different from either a stuck or dead pixel. What are they?

 

Their stuck.

Google for some free little appz that make the pixels flash quickly, and they should get unstuck.

Google something like "Fix LCD Dead pixels"

I found little appz that run in the browser which is just a rapid flashing pattern and it's fixed the stuck pixels I get sometimes.

 

Let me guess: the darker the color, the less you see them. The lighter the color, the brighter they seem, but they DO change colors to match their surrounding pixels and are not always white. They're just BRIGHTER.

I know what you're talking about. They're not dead or stuck, so no pixel exercising program is going to work. In fact, when I've seen "flashing" programs run on such screens, you can still see the white, diffuse lights (yes, they are pixel-sized) BEHIND the "flashing" pixels. In other words, they're at a level deeper than the pixel matrix. And if you look at the screen from different angles, the lights will "move" across the pixel matrix or even disappear at some extreme angles.

I've never looked into it, but I think what causes that is flaws in the backlights. In any event, nothing short of a screen replacement will help, and as you've only got two such spots, you might have a hard time trying to convince tech support to do that for you.

 

Hi, first time post, looking around the web for a description of my problem and came across this post.

I have the exact same problem as PookiePrancer just described it.

The pixel on my screen is directly in the middle and it is not exactly dead but not stuck either.

The pixel is most visible on a white background and slightly less visible on colored backgrounds.

When tilting the screen to a 45 degree angle one can see that its not exactly in the upper most layer of the screen but i would say behind the normal screen.

Tried running different stuck pixel fix apps but as PookiePrancer said i can still see the pixel directly behind the moving images that the app is producing.

Is replacing the screen the only solution or maybe i could try something else.

 

I've got quite a few pixels like that. God damn CMO.

 

Yep well, damn... I guess thats what I got... So, Dell won't replace the screen for this? I already had it replaced with refurbished one before... think they'll refuse for this?

 

Whatever the actual problem is (and I don't think it's a pixel problem, but a backlighting one), since it manifests itself as a pixel problem, they'd probably treat it as such. I can't remember what the threshold number for bad pixels is on an XPS system (I think I read 5 once), but unless you exceed it, they prob won't replace your screen. You MIGHT, however, be able to argue that it's a pretty embarrasing, visible flaw to have on Dell's finest line. I mean, a bad pixel (even one), is all anyone can see when they find it.

 

Well Good News

Yesterday i called Dell and i described them my issues using pretty much Pookies exact words since i couldn't come up with anything that would describe my issue more accurately, and basically the dell rep knew what i was talking about since according to him he had received similars calls, so he said he was sending some in house tech with a replacement LCD.

This afternoon the tech arrived and saw the issue first hand and admitted it was kind of a big issue since its not technically a dead pixel but a problem with the LCD per say so he went ahead and tried to replaced it.....

And here is where the good news end.... Basically they sent me the same model LCD as the original (Chi something) but this one was actually worse and had about 1/3rd of the screen flashing esporadically.

Long story short, put old LCD back, sending new LCD with new tech tomorrow,
