I have a simple question for owners of this fantastic monitor ;) How many people got screens with no dead pixels and how many had 1 or more?

I've had a total of 3 of these monitors, sold one and got a replacement and both of those first two were perfect. Then I decided to get a third for a dual-screen setup and the last one has a stuck bright green subpixel which shows up only on black screens. Because of the fine pixel pitch it's just barely noticable if I look hard at my normal viewing distance but it doesn't stand out at all and it's only 1 inch up and 5 inches in from the left. It also only shows up when that pixel is trying to display black.

I can still exchange it, but I want to get some idea of whether exchanging it is likely to get a perfect monitor or not with this totally unscientific survey. I wouldn't want to waste the shipping if the chances are high plus this one isn't SO bad - stuck pixel location isn't in the middle and it's barely visible at normal viewing distance. Given my experience (2/3 perfect) I'm willing to bet the replacement would be too but just wanted to get some feedback first.
 
I have one stuck pixel to the left center of the screen...but honestly I only see it when I'm looking for it. From what I understand, stuck/dead pixels are common with the lcd manufacturing process and IPS panels seem to be more prone to it than others...which could be one of the reasons (other than cost) that manufacturers are dropping IPS in favor of TN. People who buy things like the 20WMGX2 tend to fall in the "extremely picky" category and are more likely to do multiple returns until they get one that is near to perfect as possible....I'm just thankful that I got one without any major issues while AS-IPS is still around at an affordable price.
 
My NEC was perfect when new (no backlight either) but after about 6 months I found a stuck pixel in mid upper left quadrant. I have had stuckies in same place on other monitors and I wouldn't notice it except that its right where first paragraphs begin lol. I dont want to use anything to try to unstick pixel as Ive been cautioned more stuckies can result. I dont expect a consumer LCD to be perfect all the time. If I had 3 of them in 6 months I wouldn't like it but one is not a big issue all other things considered.
 
I got my nec's through bestbuy and i used the 14days to get a perfect one, it took me three tries to get one with out a dead pixel. The second one i got was a different story though, it had no dead pixels and looked perfect for a few months then shit went wrong with it. It still didnt get any stuck pixels but i noticed that in the top left hand corner that there was major bleeding starting to happen and towards the bottom of the panel it looked like there was little dust flakes through out the panel. I couldnt tell if it was the opticlear or if it was dust but it looked like dust. I ended up sending it to NEC becuase it seemed like it was dropped or something when it was sent to bestbuy, the one i got in return was perfect though!
 
So I guess stuck pixels are more common that I'd thought on these? Maybe my luck was good to get 2/3 perfect ones but the anal retentive perfectionist side of me wants to try again :p The problems later concern me though, one thing I noticed is these things run damned hot.

Still not sure if I should exchange it :confused: mainly I just don't want to waste shipping on getting the same or worse back.
 
I use my nec mainly for graphic work and pick them mainly because of their rich color
they are very close to my apple 23" and sometimes i think they are even better
right now, i have dual nec20wmgx2 in front of me, both have 1 stuck pixel
my *main* screen have 1 stuck green on the edge of the screen which is almost perfect
the other, 1 red pixel in the center about 1.5 inch from the edge


I've got both from bestbuy canada, however, they dont have any in stock so I cannot return it to them.
I've been dealing with NEC so far and they have exchange it 3 times
1st : 2 dead pixel dead center
2nd : 2 green pixel together 3 inch from top right
3rd : 1 green right in the center

the 3rd time i talk with the rep, he told me they didn't have to change it for me over 1 stuck pixel, their policy just doesn't cover anything like 1 stuck pixel but since it was right in the center he will change it...

however, i think NEC CS department is very nice and the company deserve my money beside they are pretty quick on every exchange

btw
anyone who own 2 of these in dual screen setup having problem matching the colors?
i've tried to match it in adobe gamma and the menus, no luck so far..
 
Don't want to hijack the thread but....anyone else have issues with the speakers buzzing? Since my 360 takes up my Logitech 5.1's...I left the speakers on for tv sound...yet I get the buzzzing only when not using the speakers and it's very random.:confused:

edit- it almost sounds like someone tapping out a code on shortwave radio. :p

Sounds to me like you've got a cellphone in the same room. GSM band cell phones(cingular, ATT, T-Mobile) will do this to many audio devices.

Ohh yea and i've got one stuck pixel, it's green. Tho, I can't see it ... anymore ... my NEC died about a month back, I'm too lazy to see if FRYs' got any I can swap out for, and or ship it back to NEC. I'm back on my FW900 and kinda liking it again
 
Well the replies so far throw a bad light in terms of dead pixels. Maybe the thread title isn't so good and people without stuck pixels aren't replying? :p Although it really is a yes/no question. I have an RMA # ready to use, just not sure if I should bother after all these replies, spending $100 by shipping it a bunch of times doesn't work for me.

How did the NEC return policy work? Do you get back new monitors or refurbs? And do you pay shipping to send it to them each time or only the first?
 
all return shipping fee is suppose to be free, at least thats what I was told
however, I did not use this service, because I live 5min from the NEC warehouse

after you setup an account with them and receive a RMA number, they gave me 2 choice


a: give them your visa number and they will put a hold on ur card for the retail price, they will ship it to you right away, takes about 2 days... when u get it, just pack up the old one and call them to schedule a pick you
you get like 21 days or somthing before they really charge ur visa

b.return it first and wait for a new one, call them and schedule a pick up

I did both, 1st and 2nd return I give them my visa
I return it first the 3rd time and waited 4days before i got my replacement

btw, first 2 seem to be brand new, 3rd one might be refurb coz the box looks opened

hope this helps =)

edit: I am in Canada not sure if the same apply to US
sorry for the poor english, after all it is my second language
 
Mmm prepaid label with advance replacement. That's some good stuff, I may just have to try that. I wonder what they do if the new one is worse and you decide to keep the first :p
