Dell U2412M - 16:10 IPS without Breaking the Bank
by Chris Heinonen on February 28, 2012 9:00 AM ESTDell U2412M Color Uniformity and Gamut
Of course if only the center of the panel looks good, it’s going to make images look bad with color shifting and other undesirable results. Taking a set of nine measurements around the screen lets us evaluate the screen uniformity.
There is a bit of a shift around the screen that is most noticeable in the corners and with the grayscale. The average dE for all the measurements manages to stay below 3, but all the blue swatches stay above 3 across the display. At a couple locations certain colors manage to rise above 3, but for the most part it is just blue. The rise in the grayscale is the most noticeable thing, which is what causes the high average dE results in the corners.
The Dell has around 70% of the AdobeRGB colorspace, which is close to the sRGB standard. We expected this as our blue dE values were so high and if we could do more than 70% of the AdobeRGB gamut we would see more accurate results there. However, I don’t think anyone considering the U2412M with it's high blue dE values will reject it because of its slightly smaller than sRGB gamut.

Can you provide any more feedback, or examples, on why you feel this way? Of course I don't want to alienate readers with my writing style.jamyryals - Tuesday, February 28, 2012 - link

Ah, I missed the subject heading there as I was reading through the comments. Sorry about that!bobsmith1492 - Tuesday, February 28, 2012 - link
Pot... kettle. Don't mind this troll, Mr. Heinonen.ryedizzel - Tuesday, February 28, 2012 - link
I guess I am one of the few that actually wants a 1080p monitor! My PC sits next to the 46" living room TV and its much easier to mirror the resolution on my desktop for watching movies or playing games using the wireless Xbox controller adapter.I'm just dying for a 120Hz passive 3D monitor to hit the market before I upgrade.... or OLED. ;)

This monitor can do that just fine.TerdFerguson - Tuesday, February 28, 2012 - link
Great review, thanks.phantom505 - Tuesday, February 28, 2012 - link
I went ahead and bought the AOC. As far as image quality goes, it doesn't seem like this does that much better, but you look at it much more favorably, which is odd. Now I'm not a fan of the brushed chrome, and I hate the stand, but I don't see how having a slightly larger aspect ratio makes this better than the AOC. I guess the color and stand might, but I find that hard to believe for $100 improvement.I'm more curious the ASUS Artistic series (or whatever they call it) performs with claims of low dE and 98% of the Adobe RGB gamut.

The AOC did very well for the price, as getting the eIPS display for under $200 is nice. The Dell was very close as far as color accuracy, but had the extra resolution, far better stand, USB hub, better contrast ratio (when it comes to displays, contrast ratio winds up being more important than anything else for seeing a clear difference side-by-side), better black level, and a nicer UI. The extra inch isn't important to me really, but it also stands out more relative to other displays due to the panel technology and aspect ratio.I'm working to get a review of the ASUS ProArt series in the future, as I'm very interested as well.
