Summary: This monitor is OK, but the anti-glare coating is so heavy that smallish text is TERRIBLE, as in terribly chunky and with ghosting. I tried everything to make it the best it could be. My other monitors render text much better. When I put the same window of text across two monitors, it is clear (no pun intended) that this monitor is substantially worse.
Summary: I have had two of these on my desk in a dual-monitor setup for two years now. First, the positives: The colors are far more accurate than TN monitors. The 16:10 aspect ratio is the sweet spot for productivity. The negatives: The anti-glare coating gives the display a sparkle effect that makes it look dirty all the time. White does not appear to be a solid color. Other reviews complaining about the anti-glare are spot-on.
Summary: I think Dell needs to tell in the specs or description that if you do not have a video card that supports 1920x1200 resolution it will not work. I ordered one, really excited, because of the reviews, and I think Dell monitors are the best, only to be disappointed when I hooked it up and found it would not work on my system.
Summary: I have an old 2209wa monitor with LCD back light. From what I have seen, the coating is much better then on 2412M model. Sharpness is about the same but brightness is much higher on 2412M even after calibration the screen is difficult to read, it hearts my eyes. Text mode is a little better but still is too bright. It is 6 bit panel, previous models where 8 bit, gamut is very limited and it is the same as my 2209wa. srgb 95%, adobe rgb 80%.
Summary: So after weeks of watching, I went ahead and bought two of these monitors for 265 when a resaler (Triplenet pricing) was having a sale. First impressions were good, the monitors had a simplistic, utilitarian design I especially liked and the stands seemed solid (I'm using a monitor stand so I can't comment on those). Upon installation I was blown away by the display quality and viewing angles.
Summary: After a couple of months of online research I decided on the U2412M. It looks great straight on, but the AG coating is so thick it ruins the viewing angle that should be better then a tn monitor. You end up with a sparkle effect on light colors and silver glow on dark. The farther you move off dead center the worse it looks. Why Dell would use so much anti-glare on this monitor baffles me. On the plus side if you hate seeing reflections you having nothing to worry about.
Summary: Pros: - I bought an IPS display for good color and this monitor has it. I was blown away at first when I switched to it. And I miss it now that I've returned it. I'm having trouble finding another monitor that will match the display quality of this one. - Great viewing angle without color distortion. Cons: - The anti-glare coating was more noticeable than other Dell monitors I've used. It wasn't extremely distracting, but it was there.
