Dell U2412M - 16:10 IPS without Breaking the Bank

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.

And HP has possibly a higher led pwm frequency, which itself would be worth the price difference.piroroadkill - Wednesday, February 29, 2012 - link
Better service?Hm. When one of my backlight inverters went on my U2410, Dell immediately (as in, the very next day, it turned up) sent me a BRAND NEW U2410.. seriously, it was ~1 month after manufacturing date.
I checked that it was flawless, then 2 days later they took my old one away. I even got to keep all my cables, so now I have a stack of display cables.
I'm not actually sure how you could get better than that.

And I love them both. I run them in a triple monitor setup with my Precision M4600 (Precisions display, plus both of the U2412M's)/Are they the best display out? Of course not. Are they are a GREAT bang for the buck, yes!

"I can criticize the black uniformity as the corners were a bit bad, though being a lot better in this area will likely require going to an LED backlighting system..."The U2412M has LED backlighting.

It's most likely edge-lit, so I assume he meant that it would have to be an true back-lit array to improve that aspect of it.Death666Angel - Tuesday, February 28, 2012 - link
That was what I thought as well, but then he should write that, too, don't you think? :P There is a name for what he wants: full array (with local dimming).cheinonen - Tuesday, February 28, 2012 - link
I said LED backlighting to differentiate from LED edgelit, which is what every monitor is out there right now, but I will clear that up. Sorry for the confusion.Death666Angel - Tuesday, February 28, 2012 - link
Yes, that was very confusing. Backlight just means anything that lights the LCD. It does not differentiate between edge/full array. CCFL is also a backlight, but it is mostly just used as edge lighting. LED can do both (and local dimming as a result). :-)IceDread - Tuesday, February 28, 2012 - link
Well, that's a dream I have.Does anyone know how far from my dream we are?

If you want to spend $15 or 20k for a monitor and find a couple thousand other people willing to do the same, I'm sure some company will accommodate you as best they can.
