Dell U2412M - 16:10 IPS without Breaking the Bank
by Chris Heinonen on February 28, 2012 9:00 AM ESTConclusion: A Good 16:10 IPS Display
After using it, the Dell U2412M comes out with a lot of positives and no big negatives. The screen has a nice 16:10 aspect ratio that makes it feel roomier than a normal 16:9 display, and it has a nice adjustable stand that made it easy to fit on my desk. The contrast ratio was good, power use was low, and the response time for gaming was also very good. The overall dE values were acceptable but not fantastic, and the screen was relatively uniform.
The main negatives I can come out with are that the dE values get slightly high for blues, but they do that on any monitor that doesn’t display the full AdobeRGB colorspace. Similarly the frame lag numbers look bad in comparison to other displays, but this is our first attempt with a new testing method and I made sure to select the worst-case scenario numbers as well. I can criticize the black uniformity as the corners were a bit bad, though being a lot better in this area will likely require using something other than the current edge-lit LED system or the emergence of OLED displays for the desktop, which would definitely increase the cost (by a large amount in the case of OLED).
In the end, would I buy the Dell U2412M for myself? Yes, I probably would. The fact that you can find it for $300 or less on sale fairly often and that it calibrates to a decent dE value makes it easy for someone to use as a general-purpose desktop display. Viewing angles are good, I still like the adjustability of the Dell stand, and the larger work area made for a good combination.
The closest competitor seems to be the HP ZR24w, which features an S-IPS panel but otherwise looks remarkably similar. I haven’t had a chance to see that in person so I can’t elaborate further, but that was the only 16:10, IPS panel at Newegg that came within $75 of the U2412M. I really think Dell has taken everything out of the display that they can (e.g. reduced to a 6-bit panel, no LUT, no HDMI) to produce a panel that is affordable but still very good for most people, and far beyond the 16:9 TN panels that many people might be upgrading from. It’s certainly not perfect, but it’s good enough for most people, and it is what I would want as a bare minimum if I was in the market for a 24” monitor.

Monitor Calibration and ReviewsI see all these monitor reviews where the monitor is calibrated for most accurate colors and blacks and all that...how does a person who bought the monitor go about getting it calibrated? are there local places who do this stuff? when they do it do they save the calibration on your screen?

For calibrating the display you need a colorimeter or spetrometer and software. Most include some sort of PC software, or you can use something like DispCalGUI for free. Since these involve using the LUT in your video card, you can't have it done somewhere and then bring it back home, though you could borrow/rent hardware to get it done most likely.For testing, I use an i1Pro for the calibration, which runs around $1,000 new, and an i1DisplayPro for testing the black level (around $300) since it is more accurate at reading low levels of light, but worse at measuring colors. You can use something as simple as an i1DisplayLT, though it will start to drift over time and after 2-3 years you can't rely on it to be accurate anymore and would have to buy another one. The Colormunki series has a spectro that is pretty cheap for use with a monitor, but a cheap spectro is still $400-500 or more.

If the big box stores were smart, this is the kind of service they would offer : in-home monitor/TV calibration using a customer's actual setup.hechacker1 - Wednesday, February 29, 2012 - link
They do, THX calibration and whatnot, but they charge an insane amount. Basically, it's better to just buy the colorimeter and do it yourself with various software.It's a good investment if you have many screens. Once you have it, it's a pain to work on any non-calibrated monitor, knowing just how bad it is.

"...still, I thought the explanation on the previous page would be useful for everyone."It was, thank you for keeping it in. It's always nice to know the rationale behind the testing method.
On a side note, I'm glad to see Dell at least trying to have a reasonably priced 16:10, but it still saddens me that we haven't seen much improvement in monitors (in terms of price/resolution) for so long. I can only dream that with high resolution tablets coming out, we'll see some of that trickle into desktops. For me at least, vertical space is at a premium because I have the horizontal covered by virtue of simply having more than one display.

I know right? Next gen tablets and phones are running higher resolutions than like 80% of laptops out there, and the average desktop display isn't faring much better. I don't see how market economics are allowing display manufacturers to create these amazing new 10" displays yet desktop displays have languished for so long...ggathagan - Wednesday, February 29, 2012 - link
I doubt you'll ever see that trend in discrete monitors.The entire reason for higher resolutions for a laptop/tablet is due to the physical constraints on the screen size.
If you want a higher resolution for a desktop monitor, you buy a larger monitor.
From a manufacturing standpoint, I would guess that quality control issues increase geometrically when you work with larger physical sizes. It's probably a lot easier to create a high resolution screen at 10 inches than it is at 24 or 27 inches.
Unless there's a compelling reason to do so, I doubt screen manufacturers are eager to take that on.
Far better to concentrate R&D efforts on 120Hz IPS panels and the like.

One way you could improve this part of the review is to use the same chart method that you used for power draw -- each monitor having two bars, one for "real world" input lag and one for "worst case" input lag.toyotabedzrock - Wednesday, February 29, 2012 - link
No tests of how it handles color gradients?If we are to pay more for an IPS display then it needs to be 8bit.

1200 lines is a start, but am still waiting for the ultimate answer to a monitor upgrade24", 120hz, 1200 lines and displayport
is that too much to ask?
