U2711 partial stuck pixels

elbow · 14 May 2012 at 23:42

Hello OcUKers. About a week ago I bought a U2711, my first IPS screen, and I have a slight query over the panel quality. To be clear this isn't me being super picky as I can certainly live with it, it's just that I wonder if I've got myself a 'friday afternoon' panel.

So it goes like this: clustered mainly around the top centre and bottom right are literally dozens of tiny pinprlcks of light when viewed against a totally black background. These are visible to the naked eye, green standing out the most but red & blue are also represented. Now the weird thing is, they aren't stuck pixels, at least not full ones. If I put the white mouse cursor next to the brightest one and look at the screen with an 8x loupe, you can see the cursor made of pixels and each pixel is comprised of three vertical bars of RGB. The bright spots on this panel are at most 1/3 the size of the corresponding bar of colour in a pixel. Move the mouse over the bright spot and the whole pixel lights up - there are no dead pixels at all - move it away and you have a fraction of a pixel still lit.

If I'd bought it from a retailer I might have been tempted to swallow the carriage and return under DSR but alas this was a new boxed item from a private seller on a certain auction site. I see the Premium Panel guarantee can be invoked with just one stuck pixel but as I don't have a single whole stuck pixel I'm not sure how Dell would play it. To other U2711 owners, this isn't a known trait is it?

I've checked & it is covered with 1000+ days remaining I just wasn't sure whether I'd have to assert myself with Dell support to recognise these as proper stuck pixels. A moot point perhaps as my experience with Dell swapouts at work is that they just send a courier to drop off & pick up.

Thanks for the reality check, I decided to pay the extra and go Dell for the peace of mind warranty but don't have any experience with anything fancier than TN panels. Indeed this U2711 is about to replace a well ancient 22" Diamondtron CRT on my home computer.

yes they do they will send u a monitor before u need to return the one u have thats the deal so u will not be without a screen

normally u will get a leter revision also so if urs was a rev a09 and the latest is rev a12 you will likey get a checked a11 or a12

as a replacment and in 2 year time if it reva22 thats the latest u will get that in place of you 2 year old rev a09 thats why its so worth the money to go dell imo

its onsite not oack it all up and wait for a decision its basically free no cost returns and no down time..

btw diamontron was that a mitsubishi screen ? big black 22 beast .. i had one and its one of the best ever screens had it years agao awesome thing weighs a ton

Thanks both, I've got a day off on Friday so I'll call it out to Dell for then.

craarc: yes, a Mitsubishi Diamond Plus 200, running 1800x1440 @ 69Hz. It cost a packet when new but must be something ridiculous like 14 years old! Shame to get rid of it really.

FML. The replacement arrives and it's a refurb, mfg date of 2010 and enough dust & scratches to prove it. On top of which it has two dead pixels, one in common line of sight. My research leads me to believe that Dell will only swap on 6 dead pixels (as opposed to a single bright pixel) so I'm going to bitch about the poor condition of this one to try and get monitor #3. That's two for two with pixel defects, do people ever get flawless U2711s or are you all living with some pixel faults?

Yep, throwing out working stuff is a tough act to do for the thrifty. I recently did this for a superb Philips CRT widescreen TV. Worked absolutely perfectly after 10 years and was immaculate. But what do you - hold onto an house full of obsolete junk that no one wants?

Another example, in my garage I have a superb Sony 19 inch flat screen CRT monitor. It is a fabulous monitor, works perfectly and I cannot bring myself to get rid of it since it cost £500 when I bought it !! I was thinking "well someone will want it"....You know what? No one does......!!! So tomorrow its going to the Council recycling place.....

Have to be ruthless or you end up with an house full of tatt....!

Sorry, sermon over...
