Re: U2410 Green/Pink Failure Analysis

I just bought two Dell U2410 monitors and as soon as I connected them I noticed the green hue on one of them.  I have a beautiful picture of the Grand Canyon, which I have been looking at for years on my older dual monitors - but as soon as I turned the new monitors on I noticed a big difference between my left and right monitor.   There was a green haze over the left and despite repreated adjustments, which actually improved the appearance - I could never get rid of the light green haze over the one monitor.

Re: U2410 Green/Pink Failure Analysis

Mmmmmh...

Just got a U2410 and, using the factory default, it has indeed a slight color uniformity gradient : greenish on the left bottom -> redish on the upper right (I've to say I'm quite picky about lcd display).

Slight but noticable on a full white or grey screen.

I tested two HP LP2475W one year ago and both had this same kind of problem to some degree (same LG panel type).

I was able to strongly minimize the gradient by using the "Cool" color mode. Far from ideal, but you may want to give it a try...

It sounds logical as this one boost "Blue" against R and G.

Apart this color unformity issue , this monitor looks great to me...

Re: U2410 Green/Pink Failure Analysis

I registered just to express my disappointment in the company's decision to not directly address the Green/Pink gradation.  As a potential buyer, this vastly changes my opinion of the product and your company.  I was about to pull the trigger on buying this monitor, but no longer.

Re: U2410 Green/Pink Failure Analysis

I agree with odindusk. I was also seriously considering purchasing this monitor and I'm very disappointed to see that Dell is not acknowledging this tinting issue. From what I've read online, this seems to be a major issue with this particular monitor and it's really the luck of the draw if you get one with this problem or not. I don't want to take this chance, especially when Dell will not try to fix the issue and charges you if you want to return the product. I experienced a similar issue this year with Samsung (not wanting to acknowledge there was a sound problem with some of their LCD TVs) and I really do not want to go through this again. I really wanted this monitor and was going to buy it this week because of the sale going on, but after reading all of these complaints, I am going to pass and look into other options. This is a big disappointment.

Re: U2410 Green/Pink Failure Analysis

Obviously, the intensity of the issue is very variable from one unit to another.

For me, using the "Cool" color mode solved it (using sRGB did not helped). The gradient is no longer noticable (of course in my case it was only a slight one).

I know it's not ideal, but maybe a proper calibration with R nad G tuned down could give also good result.

Btw, no LCD panel has a perfect uniformity (except high-end models of Eizo, Nec or others, and even with them you can have bad surprise).

I guess from what I've read that for some 2410 units, the tint heterogeneity is too strong to correct it, and in the same way for others 2410 units the tint heterogeneity is nearly not existent.

Dell should really asks LG to only provide them with panels with minimal (to define) color heterogeniety that could at least be corrected by calibration.

Re: U2410 Green/Pink Failure Analysis

I suggested, not entirely seriously in the other thread on this (U2410 Green/Pink Tint Issues) that perhaps Dell could select out the good ones for us instead of having us keep sending them back until we get an acceptable one. 

It is my understanding that the availability of a reasonably accurate sRGB mode for viewing non colour managed images on a wide gamut monitor sets this apart from anything else in the price range.  I liked the two I had very much, apart from the colour variation.

Given that the following are true:

  1. Dell are not going to apply proper quality control to all units;
  2. some units are accaptable for photo and graphic work;
  3. these good units will remain so over their lifetime (currently not known); and
  4. the multicoloured screens are fine for many/most people;

then all Dell need to do is pick some good ones off the line, badge them "U2410 Graphic" or some such name, and charge a bit extra for them.  They could guarantee the colour across the screen on these ones, and any that fail can go out as the standard model.

Re: U2410 Green/Pink Failure Analysis

I also registered just to express my disappointement ad DELL about how they are handling this monitor issues, I work in SMT production and I know very well that is not a huge change to actually create a matrix of 5 calibrators to automatically check each screen out of the production line, is not like the TESTER has to measure the screen for each of the 5 points thus requiring more time for testing which means the monitor costs more...the issue here is that measuring 5 points across the screen may means that DELL may have a much lower sample of usable MONITORs because 5 out of 10 may fail the 5 points test against 1-2 out of 10 based on the current 1 (center) point testing.

The thing that DELL doesn't understand is that we would be willing to spend £50-60 (~$100) for a monitor that has been tested across different areas of the screen, at the end of the day people are still buying the UltraSharp W2408 which is much more expensive than the U2410, what I mean is that people that are willing to get a good monitor are also willing to spend some money on it.

The other point to take into consideration is the fact that this is the same panel that Apple uses in their Cinema Displays, very few Apple users have the same level of complain about Green-Pink tint issues and bare in mind that the Apple display doesn't have any kind of OSD menu or even brightness settings!! I take that LG is passing to Apple all the good yelds panels at full price and then sending to DELL (u2410) and HP (LP2475w) the rest of the panels that didn't quite make it for a discounted price, I wouldn't be surprised to open my U2410 and find a big "GRADE B" sticker on the back of the LG panel.

Dell tought that out of 100 monitor only probably 5-6 people would figure this out and ask for support/exchange.

At this point I will probably start the DELL exchange lottery until I get a good one, I work from home so I got time and patience to spare to keep exchanging monitor until the end of the 3 years warrant or I'will probably return this unit and wait for the next revisions or wait for some other manufacturer to start selling a similar unit. In the meanwhile I'll make sure to tweet and blog about this unit just to make people aware of the possible issues.

Re: U2410 Green/Pink Failure Analysis

(1) All received captures were tested and are within manufacturer specifications for color gradation.
(2) The Color Calibration Report results are generated by testing the center of the monitor, not the left and right sides.
(3) There will not be a firmware written for Green/Pink color gradation.
(4) To alleviate this -
* Open the OSD (On Screen Display)
* Go to Color Settings
* Go to Preset Modes and change it to sRGB
(5) We are still awaiting the firmware fix for the Graininess in sRGB and Adobe Modes

 

Well I just received my monitor today, after ordering yesterday, and being blind to the fact of all these problems with the U2410, had I known of these problems, I wouldn't have wasted my time ordering one in the first place.

It still sits here in its box, unopened and untested, and that is the way it will remain so, until the courier comes to collect it on Thursday, thus returning it back to where it was bought (at my expense I will add) for a full refund.

I am not prepared to enter into another 'Dell Lottery' game of cat & mouse, been there and done it all before with my 2007WFP a few years back.  I can also see that Dell have not changed their attitude one little bit in these years that have passed since the last fiasco.

The above 'statement' numbered 1-5 is an absolutely shocking response to those who have spent good money on something not fit for public sale, hence I will not be opening my box to find out either way, nor will I be purchasing any Dell product again.

I urge people to think twice before spending this sort of money on the Dell U2410, otherwise you will find that getting the quality product you paid for, depends on the roll of a dice.

Awful!

Re: U2410 Green/Pink Failure Analysis

Probably start? Base on what reason you are gonna exchange? I don't think they will allow anymore exchanges for tinting issues. Just return this monitor.
