Here's Anandtech's reviews of the color accuracy of the Dell U2412m and the Galaxy Note 3 Movie mode. This is of interest because that site is using the same Gretag Macbeth patch test to get average Delta E readings for both screens; if you go to other sites, they will have different Delta E color accuracy results because they do different tests.
The Dell u2412m scored 7.41 average Delta E when uncalibrated, and 1.71 when calibrated. The Galaxy Note 3 in Movie Mode scored 4.62. The lower the Delta E is, the better. A value of 3 is considered good because most humans won't notice color differences below that, and 5 is the upper acceptable limit.
The Galaxy Note 3 in Movie Mode pushes pretty close to the limit, but does pretty well for a phone by being under the limit at all. An uncalibrated U2412m goes way beyond the limit; but a properly calibrated U2412m is far, far better than the Galaxy Note 3. Note that this implies that pictures will probably look different either way on your U2412m compared to the Note 3, whether the U2412m is calibrated ( much more accurate) or uncalibrated (much less accurate).
We have no way of knowing how well or how badly your u2412m is calibrated since you report that you are using some ICC profile you downloaded from somewhere.
Most monitors that you buy will probably have worse color accuracy out of the box than your Galaxy Note 3 in Movie Mode until you calibrate them.
There have been impressive monitors recently that I wanted to buy, but they used AG - so I passed..such as that 4k 40" VA 5k:1
"According to reports the screen surface is semi-glossy anti-glare which is pleasing."
http://www.tftcentral.co.uk/news_archive/31.htm#philips_bdm4065uc
Can you do a 40" display with no AG at all and not have a problem with reflections?
Pretty obvious they are tested with two different methodologies....

In the previous page of the U2412m accuracy review, they state they "check color fidelity using the well-known Gretag Macbeth color checker chart" to obtain the uncalibrated average Delta E of 7.41 and calibrated of average Delta E of 1.71.
In the Galaxy Note 3 review, they state "in the all important Gretag Macbeth patch test, Delta-E is pretty low" and give the average Delta E of 4.62.
What did I miss that is so obvious to you?
Because of the large change, we will be making a break from everything in the past and going with DeltaE 2000 for our measurements. Because of this the numbers from this review and going forward are not comparable with older reviews as different DeltaE formulas cannot be compared. I will write a longer article on this new measurement system soon, but this will be our first use of it for a desktop display. (Anand has been using portions of these tests for tablets for a while now.)
No, it's not. My phone is displaying accurate colours than my monitor, I will say that as many times as needed, because it is the fact.Stating that his phone is displaying accurate colors is just plain wrong.
Course you can, but not in the topic which I created and you couldn't keep things civilised.Let's be clear: I can post where ever I please.
I know what accurate colours are, it's not rocket science. However the same can't be said for you at all.I'm telling you what you're saying if wrong, but clearly you do not know what accurate colors are and cannot interpret the information in the review. Either way, there's a list of recommendations; do what you will.
Oh dear! A IPS monitor needs to be calibrated to show accurate colours? Wow!

No, not ironic, quite simple rather. He asked me not to post in my own topic where I am merely asking a question, that too in a rude way, and I simply asked him to stay out of this topic, as clearly it is wasting his time. However I get it, some people just need to troll.I also think you should stop posting here (because you're wasting your time.)
Ironic that he tells you where to not post, after asserting that he can post where he wants.![]()

the only fact here is that you like your phone's color more than your monitor'sNo, it's not. My phone is displaying accurate colours than my monitor, I will say that as many times as needed, because it is the fact.
it's not rocket science. it's called colorimetry. i suggest you read up on it a bitI know what accurate colours are, it's not rocket science. However the same can't be said for you at all.
not sure if troll

The NEC 2490wuxi (you have linked Snowdog's 2009 picture of one with tape on it) had an official uncalibrated contrast ratio of 800:1, when calibrated it had contrast ratio as low as 200:1, you are looking at A-TW polarizer film not anti-glare coating, and it was considered one of the most color-accurate monitors of its time, so you managed to lie three times in one sentence.![]()
@Snowdog
EIZO have few models with filter that is analogous to A-TW
There are also those three 24" models with A-TW
24" HP DreamColor LP2480zx
24" LG W2420R
24" Quato IP240ex LED
Darn, I forgot to mention it, I did calibrate the unit, well just by applying the ICC profile which was available on, well where was it, tftcentral or something?
I have been testing this thing for quite a long while, and no, I didn't see random sceneries on internet to check colour reproduction of the monitor. I borrowed my colleague's 5D Mark (or something like that) to take pictures of flowers in my garden, especially colours like green, red and blue, as they matter most. Then I reviewed those photos on my monitor and on my phone (on my t.v. too, but that's not really what I want to say here), along with the actual product, the flowers in this case, I have lost count how many times I've compared them, well, I've been doing that with different other items too, finally I bothered to ask today, the monitor is doing worst if compared with that other two items, being the most over saturated unit! Yes, if I change the tv's profile to Standard and phone's display mode to Adapt then the monitor will be the best performer, but that's irrelevant.
I would add that the calibration has to be performed every few months, even if the monitor comes out of the box with perfect colors it will change over time.Applying an icc profile (actually a 1d lut) is not calibration. To calibrate, you need to take direct measurements of your own display.
No, also quote the whole line.not sure if troll
Course I do. How long did it take you to understand that? It is posted very clearly on first post!the only fact here is that you like your phone's color more than your monitor's
I will, when I have the time. As I said, not everyone in the world has the time to do post purchase stuffs, also this isn't the cheapest monitor out there as well. At least a decent enough calibration should be done in factory. The factory calibration of U2412 for being a IPS panel is nothing but ridiculous.it's not rocket science. it's called colorimetry. i suggest you read up on it a bit
There's no doubt about that.Well if you aren't using it for professional graphic editing then IPS is second worst screen technology after TN for general usage
Especially cheap 6bit IPSes like that Dell
I don't posses the necessary tools, I don't have the time mate.Applying an icc profile (actually a 1d lut) is not calibration. To calibrate, you need to take direct measurements of your own display.
I don't know that much, all I know that I took a shot of a blood red flower, and I wanted to see the same (or near enough) colour on my monitor, but I saw a flower with orange tint, which was not the case on my phone (it was at least red, nowhere near orange and at least comparable with the actual flower), and shockingly even the TV showed better (not that orange) colour output than the monitor.This is no way to test color accuracy. The color of the actual flowers is determined by the spectral reflectance of the flowers. The color that the camera encodes the flower is determined by the spectral transmission of the camera's RGB filters, in combination with the color processing that the camera itself performs on the raw image data.
So unless the camera is a true colorimeter (device independent, that satisfies the luther-ives conditions), then you can't use your camera as a color measuring tool.
What sarcasm? I simply asked a question! Yeah I guess you are done, if you take a mere question as sarcasm.The answer to both of your questions is yes, but other than having been wrong about Anandtech's testing methodology (I'm not afraid to admit when I got something wrong), I'm not sure what I've done to deserve your sarcasm, so I guess I'm done here.
What are you trying to pull there? I don't understand what that time stamp means!Just saying.
The unfortunate truth is that you can either spend the time to learn and the money on correct tools, or you can deal with the limitations of factory calibration. Nobody is going to wave a magic wand and make things perfect for you, because it is not technically possible unless you purchase a professional monitor with an integrated calibration device (and enjoy spending professional quantities of dosh for the privileged).I will, when I have the time.

Why do you think almost all TV's have high contrast glossy VA panels?

If you person preference is for oversaturated but inaccurate colour, then you would be better served by purchasing a wide-gamut monitor and treating it as sRGB. All colour will then be highly saturated.
What are you trying to pull there? I don't understand what that time stamp means!![]()
Even if one likes some oversaturation still stay the fuck away from wide gamut. It doesnt just oversaturate, but turns every color to neon. Its way worse than mild oversaturation in phone screens.
I don't know that much, all I know that I took a shot of a blood red flower, and I wanted to see the same (or near enough) colour on my monitor, but I saw a flower with orange tint, which was not the case on my phone (it was at least red, nowhere near orange and at least comparable with the actual flower), and shockingly even the TV showed better (not that orange) colour output than the monitor.
Now if you tell me that what I saw on the monitor is the actual colour of the flower, I can't agree with you there. What is the actual colour of the flower is the one I see with my naked eye. And that's why I did that comparison. I have near perfect vision, so my test could be non-technical but I don't think it it deserves that much discredit like being mentioned here.
