Dell 2407WFP Dead Pixels

That is basically because Sony are operating a zero tollerance on dead pixels.
The same goes for Nintendo on the DS - you can get your unit replaced for a single dead pixel.
However, with an LCD monitor they can be supplied to you with up to 4 dead pixels and still be OK as per the TCO2003 specifications.
These are legal specifications that you should be making yourself aware of before purchase.

So although you could use the Distance Selling Act to return an LCD with only a single dead pixel, once you've past the time this act gives you a single dead pixel wouldn't be classed as a "minor defect".
Because the full specification for the device allows for x number of dead pixels before it is considered defective.
 
Yes but unless the product is advertised as "might come with a dead pixel" then i am having none of it, I dont care what the industry standard is at all.

If I am paying £550 for a monitor it WILL have no dead pixels, as a consumer being expected to just be happy with an annoying as hell dot on my screen "because" is ridiculous imo. I realise perfecting the technology would mean soaring costs but hey call me selfish, I am not keeping costs down if it means I get what in my mind is a defective monitor.

I am a reasonable person, and most people will not tolerate a dead pixel my logic goes like this.

"Is this pixel working correctly?"

"No"

"So is it not working correctly?"

"Yes"

"So this monitor has a minor defect?"

"yes"

"Sale of goods act covers me then."

:o

These are legal specifications that you should be making yourself aware of before purchase...

No attack to you personally, but that is absolute BS, I can walk into a retail store as a "non-internet enthusiast [who might know about this already]" and pick up a PSP and not find out until I get home and open the manual that Sony wont accept it, pixel policy is not on the box, I cannot make an informed decision, it goes back again and again and again until its fixed or there is a disclaimer on the box or product description from manufacturer.

If you or indeed anyone else wants to throw around the "But ISO says" then here is ISO for you.

Updated in 2001, ISO (International Standards Organization) 13406-2, the standard that all monitor manufacturers refer to, stipulates an array of ergonomic requirements on the quality of liquid crystal display images. The criteria involved are brightness, contrast, reflection, uniformity of brightness and colors, flicker, character analysis and ... defective pixels.


The standard also defines four levels of quality. Class 1, the highest, allows no defects at all. Class 4, the lowest, allows up to 262! Fortunately nobody refers to it. Apart from some exceptions, all manufacturers refer to Class 2. If they do not specify, the monitor is Class 1 by default and you can have it changed at the smallest pixel defect.

So unless the monitor is advertised as being a class 2 product then they have to use standard 1, no defective pixels,sub pixels, clusters or mixed bags of peppers.

I have one bang in the middle and they wont swap mine, im tempted to call them and say that the screen is turning itself off after 30 mins, however if i do that and get another one it might have more dead pixels and i would be snookered.
 
good post Azure, if a dead pixel is not a minor defect why are some monitors perfect. I have 20inch dell with no dead pixels or problems, it shouldn't be a lottery

It goes back once, the store explains the policy to you, gives you the chance for the one off exchange for the reason or offers you a refund. You wouldnt get away with returning the item a 2nd time for a dead pixel.
 
I think this whole dead pixel policy thing is an absolute **** take!!! If a monitor is not perfect it is just NOT good enough.

There is no way I would accept if a company told me they wouldn't replace a monitor that had dead pixels. Even if it took an 8 page letter to the managing director ;) :p

But saying that I always take insurance on things like this so if they did try to mess me about over it I would just throw it down the stairs and get my replacement that way so they couldn't sell it to some other poor fool.

Verbal contracts, not worth the paper they are written on
 
Gonna try and get mine swapped, shall i just say it turns off? They arent going to test it and find out are they. If i get a new one and its got more dead pixels i will not be happy.
 
I'm afraid this thread does just show a general lack of knowledge when it comes to the manufacturing process behind LCD's.
OK, answer this question:

1. Taking the current price of LCD panels.
Would you be willing to pay 50% - 100% MORE for your panel if it was guaranteed not to have any dead pixels?
We're not talking dead pixel checks by companies, I'm saying that every LCD panel that left the factory would be guaranteed not to have any dead pixels, however it would cost 50% - 100% more?

This is not a choice by the way, all panels would be perfect but all customers, even if we were willing to take the risk before will have to pay the newly inflated price.

If you'd be happy in that situation then you don't need to go any further.
You are not going to be swayed in the least but what is written next.
However, there is a reason why panels are so cheap now and that is because they allow for a certain number of dead or stuck pixels during the manufacturing process.
This process has greatly improved over the years.
When I first started in the computer industry as a computer salesman we sold our own brand of laptop.
It came with a mono screen and an upgrade to a dual-scan colour display was an extra £200.
To take it to a TFT screen added an extra £500 on top of the price again.
This was because one in every four panels was a thrown away - they failed testing, components couldn't be harvested and they were literally thrown away.

The process has come on leaps and bounds now, however so has the technology behind them.
You're 20" widesceen display has over 1.7m pixels on and that is a lot to get perfectly right.
The only way all manufacturers could guarantee no dead pixels would have to be something similar to how it was - I'm sure component harvesting is possible these days, but would still be time consuming and expensive.
Add in the testing of each individual panel at the manufactuing level...

So, if you would all be prepared to see an increase in panel prices I think you should make it known, speak to these manufacturers.
Tell them you demand a 100% perfect panel every time, however make it clear you are prepared to pay the extra money to cover testing and the harvesting of components from failed units.
If it were possible for a production line to make 100% perfect panels every time then they would do it.
However to make these things affordable something has to give.
 
that's just an excuse and its something that doesnt happen with any other type of electronic goods. i have a dead pixel on my acer and honestly it doesnt bother me that much. if it did it would go straight back. The bottom line is they should clearly be labled as class 2 products if they are being sold in that manner.

The standard also defines four levels of quality. Class 1, the highest, allows no defects at all. Class 4, the lowest, allows up to 262! Fortunately nobody refers to it. Apart from some exceptions, all manufacturers refer to Class 2. If they do not specify, the monitor is Class 1 by default and you can have it changed at the smallest pixel defect.

can we confirm this?
 
like to ask off topic question if i may.. anyone used component's on thier dell 2407? what is the pic quality like? reason i ask is that recently got my dell and when using component's i carn't seem to get a real good picture it's all in monchrome if i adjust colour's in setting it doesn't seem to affect it at all. work perfectly on the rest of the connection 's.wanted to hook up ps2 on just see if i could get tv quality image on the dell
