Re: U2410 Green/Pink Failure Analysis

I have no doubt at all that this monitor is amazing if you get a good one. The reviews were quite good across the board and it seems that many people are happy with it.

 

The point that makes me stop and think before buying it is "What if I get a lemon, one that DOES have the annoying tinting"? What if I am in that 5% (or whatever the % with problems is) that has to go through the hassle, shipping fees, restocking fees, etc.

 

If Dell acknowledged that the bad tinting was a problem, and offered to treat it like a defective product, then I'd feel reassured. I do not want to have the monitor for a month (all the while attempting to tweak and fix said problem) just to have Dell tell me "sorry you can't refund since its past X number of days".

 

I'm sure you can see why I worry. I obviously know that not all the monitors will have that tint/dithering issue... but when dealing with a $600 monitor I guess I expect a bit more (like the Zero-dead pixel policy: This is EXACTLY what I expect... so why the lax restriction on coloring?).

Re: U2410 Green/Pink Failure Analysis

I can understand, for sure. I was in the same place myself ~6 months ago, as I said.

As for why they won't step in and make a statement, my guess is that they simply don't have the testing procedure in place to ensure they don't get too many returns, and can't justify the cost of the testing or the returns, both of which cost money. They likely can't pass the buck to the panel manufacturer -- I wouldn't be surprised at all if they have a contract for the dead pixel policy that allows them to do so, but weren't aware of the tinting issue ahead of time and didn't get that contracted, so now Dell themselves would have to bear that cost.

$600 isn't close to professional monitor pricing -- it's an expensive consumer monitor, but a consumer monitor nonetheless. Pro monitors of this size can easily run into the multiple thousands of dollars.

You get what you pay for. At $600, I've found it to be quite a lot..

Re: U2410 Green/Pink Failure Analysis

I sent back two of these 18 months ago.  The difference between the two sides of the screens was far greater than any changes that could be made to the centre as a result of calibration with a colorimeter.  As I want a monitor that can be calibrated to show me accurately what my prints from calibrated printer/ink/paper combination will look like, this is not much use.  My printers produce even colours across the picture.

Back then, I and others suggested that we would be happy to pay a premium for a screen in which the colour variation was not noticable.  Clearly such screens are aound as many colour critical users attest.  Equally there must be many people out there who either don't notice or don't care about the green pink tint, because while some people have complained about them, many must have accepted them.

The brightness range on my Diamondtron CRT screen which got me out of trouble then has dropped badly, so I am looking for a new monitor again.

So please Dell, pick some good ones off the line, test them right across the screen and put them out as a photographers version at a premium price.  I suspect you could do this for a lot less than the NEC PA241W which is nearly twice the price in UK and is not going to be twice as good as a "good" U2410.

Re: U2410 Green/Pink Failure Analysis

Does the latest Revision (A04) fix any of the problems mentioned in this thread ?  I planned to purchase this monitor but not if it's still messed up.

Re: U2410 Green/Pink Failure Analysis

I think that this is a hardware quality control issue.  The specification is not tight enough.   If their Revisions had resolved it Dell would have told us.  Very sad, as it has excellent reviews of units with no tinting.  There is a cnet review of one with tinting, however.

You can pay a lot more for one with the technology to fix the problem or take a gamble.

Re: U2410 Green/Pink Failure Analysis

I am in the market for three 24" displays.  Over several days of reading reviews on technical sites I hoped that the often mentioned Pink / Green tint problem appeared in early models but would have been corrected by now. As a long time Dell customer, I realize these forums tend to attract people who have problems with a product while thousands are quietly satisfied.  That said, I am disappointed and frankly surprised that Dell has not corrected an obvious quality problem that is frustrating a large number of customers and causing an even larger number of potential buyers to shy away from this product.

I really tried to talk myself into buying three of these but it sounds like a complete crap shoot whether you happen to get lucky.  And if you do have a bad monitor, it's going to cost money to roll the dice again until you either get lucky or give up.  I'll keep looking.

Re: U2410 Green/Pink Failure Analysis

@CherryBark

I've attempted to get in contact with Dell on the 18th (May) through two different email tickets and via this thread and I have yet to receive any e-mails back, nor has a moderator/technician responded in this thread... While that is not extremely terrible it is annoying, especially if you are trying to take advantage of a sale price.

Maybe I will try to make a new thread and hopefully not get banned for it.  I also plan to call directly, but that will have to wait a little while.

Re: U2410 Green/Pink Failure Analysis

I just came up with a curious thing.  Dell say that the U2410 complies with TCO 03. Amongst other things TCO03 specifies

Light levels without color tint - No color tint introduced at lower light levels.

Uniform color over the entire screen - No distortion of colors.

Chris, can you explain how you are able to say that the green /pink tint is within spec. and yet claim compliance with TCO03, please?

Re: U2410 Green/Pink Failure Analysis

Light levels without color tint - No color tint introduced at lower light levels.

Uniform color over the entire screen - No distortion of colors.

Just looked up TCO'03 myself, out of curiosity, and it doesn't say any such thing. What it actually says is:

"Δu'v' = 0.01 for the maximum colour deviation between measured active areas on the screen that are intended to maintain the same colour."

"For an FPD in landscape mode, the Δu'v' between areas on the left side and the right sideof the screen when it is positioned at +30° and at -30° horizontally to the screen normal shall be = 0.025."

"The greyscale steps to be used are 255, 225, 195, 165, 135 and 105, and each should be measured in the centre of the screen. The maximum difference in either u'or v' identifies those steps where Δu'v' should be calculated. The Δu'v' shall be = 0.02."

In other words, color variation is allowed, but must be within a certain range, which is greater when viewed off-angle at the screen edges, and allowed to vary still further when luminance varies. Incidentally, the luminance test isn't even performed anywhere except at the center of the display. And to claim compliance, Dell has to have submitted a test report performed by a TCO-authorized testing laboratory. In other words, a test lab somewhere has stated that the display meets this test.

Re: U2410 Green/Pink Failure Analysis

Thanks for that clarification. I think I was looking at a summary of some sort.  Doesn't really solve my problem if I have to keep sending them back to get a good one.  Think I will have to bite the bullet and spend 800 quid (GBP) on something with proper colour control.

Having said that, I note that in your last paragraph you say that a lab has to have tested "the display".  In practice, they will have tested "a display", and we know that many are acceptable to people doing colour critical work.  Do we know that the screens with noticeable green/pink tint are actually within the spec.?
