Summary: I purchased this monitor and it failed (will not power on) after 18 months. It has a three year warranty and I have been working with Dell to have it replaced for two months, with no luck. Working with Dell customer service been a very frustrating process. You may want to investigate other monitor manufacturers in this category if you want a reliable monitor that has warranty support by the manufacturer.
Summary: I saw the bad reviews for this monitor but I decided to try it anyways and I regret it. I got this monitor in today and within 15 minutes of unpacking and setting it up I was putting it back in the box to return. I should have known better. I had previously tried a U2410 and sent that back for having a green tint on the left of the screen. This monitor has the same problem but is actually worse.
Summary: Seller = Awesome. Dell = Not so much. Got monitor unboxed, all hooked up and found that half of the screen was just a block of white. The other half was almost completely devoid of color, looking washed out. The Dell computers I've used in the past have always been terrible, but I was giving this monitor a chance based on the supposed color accuracy and (mostly) glowing reviews. I work in design and 3D, so I needed a large monitor with accurate color at a decent price.
Summary: I purchased this monitor and about 3 months later it began having vertical green lines over the right half of the screen. After a week long run-around with Dell, they sent me a replacement, which was a refurbished monitor. The refurbished monitor had a dead pixel in the center of the display. This will certainly be my last dell product. I would recommend other buyers to consider alternatives.
Summary: Text on white background is impossible to look at because of 'sparkle' effect created by anti-glare coating. It feels like you looking at text through a layer of dust. I know that good anti-glare coating is possible because I used Dell's own 24 inch model, Thinkpad IPS and MacBook Pro with anti-glare option. All of them are very good at suppressing reflections and not ruining text at the same time. My recommendation is to do some research on this before spending 900$.
Pros: I'm sure it'd be nice very expensive monitor for $1300 I was fooled in to buy.
Cons: I orderd this on Oct 7th and wanted to cancel after 1 hour. Customers service promissed to cancel. Next day it was marked "Shipped"! Within hours monitor went for sale $400 dollars less. No price adjustment. For return must pay over $200
