TFT screens and defective pixels
 
Just bought a new 17" Philips TFT monitor and am quite happy with it, stonking resolution, but have noticed one dead pixel.

According to the guide book, this is within their 'tolerances', and following a bit of web research, it would appear that this can normally be expected.

What do you guys think, because I really can't be bothered to drag it all the way back to the shop? Is it likely that more will go over time?

I don't think any more will go. It's a problem with the manufacturing of the screens. Most companies say up to 3 pixels and they regard it as ok and won't take a return. I was a bit unsure when I bought mine, but luckily it had none when it arrived. Is it slap bang in the middle or somewhere out of the way? Is it dead, ie black or a funny colour?

I don't think having a dead pixel makes it any more or less likely that more will go in the future. Like you said, 1 or 2 dead pixels is within tolerance, so if it doesn't bother you then don't worry.

As for taking it back to the shop...better check the return policy of the shop you bought it from. I know many shops won't replace them if there are only a couple of dead pixels.

When I got my laptop it had a dead pixel in the top left hand corner of the screen. Which - same as you I guess - I found out was 'within tolerance' Actually mine went away the first time I cleaned my screen.

I've not heard about pixels getting worse - but I suppose it's possible.

This is very true - and it's also why I bought my last tft screen (the sharp £200 one) from argos :) because if there was a dead one I could take it back under the money back gurantee thing...

It's a little red sod about 3" in from the left and 5" up from the bottom, but I can live with it for the lovely picture. It's great to have this higher res, so I can happily surf with the browser only half maximised :)

I think its wrong to accept dead pixels i mean you pay enough for it why should you not have a perfect screen i think its up to consumers to complain and maybe they will do somthing about making all screens perfect have you noticed when you go in a shop how many screens have dead pixels non so you should expect the same of yours

If its red then it's still alive, maybe it will go like dill's

If it annoys you return it with a spurious intermittent fault, don't say its because of a dead pixel, cos like you say its within tolerances and they won't replace it.

I think I'll live with it, who knows the next one might have 2 dead pixels.

You only pay for it if you pay for ISO13406-2 CatI

most monitors are in the II or III catagories. I is hideously expensive.

Any views on 14" TFT monitors, other than screen size are there any other factors

All the 14inch tft monitors I've seen were 256k colours not 16million.

This may have changed however - but i'd check first.

i believe its 5-7% pixels dead before a manufacturer will 'care'.
