Apologies in avance for hijacking/diverting this thread a little. A bit off topic but relevant when compared to the Dell U2410.
Guys if you are looking for a hassle free monitor with an IPS screen please have a look at the NEC EA231wmi.
Mkay is right the Dell is NOT a premium monitor. It appears to be an attempt by Dell to cash in on the burgeoning enthsiast crowd (like us) that see the value in an IPS screen and want something better than TN/PVA.
IMO their thinking is along the lines of give them the IPS, don't worry about the quality, they (hopefully) won't know the difference.
I also went through 4 spectular failure examples of the Dell U2410 and I will definitely not be subjecting myself to that kind of unpleasantness in future.
I can honestly say that the NEC EA 231wmi despite its E-IPS screen is possibly the best monitor I have seen on the market ATM considering its price.
Brilliant design, build, picture quality (subjective and tested is simply amazing).
I calibrated my monitor to average deltaE of 0.34 with a maximum 0.87, black level of 0.15 and luminance of 125 cd/m2. This is miles better than anything I could get with the Dell U2410 even with its claims to accurate colour. Stretching the memory banks here but I think the best calibrated result I got with the Dell was average deltaE of 1.5 ish and maximum of 3-4 which is not very good for a monitor claiming to produce "amazing" color accuracy.
I really am chuffed that a monitor at this price (it can be had for around 280 euro) can produce such quality. Its possible that the good image quality is also due to the fact that the resolution of the NEC is 1920 x 1080 despite being 1 inch smaller than the Dell producing sharper images with a smaller dot pitch. This needs to verified though.
Also worth mentioning is the fact that the NEC does not really need to be calibrated as it is perfectly accurate out of the box in sRGB mode (validated average deltaE of 0.73 and max of around 1.59 with black level 0.13 and luminance around 120 cd/m2).
If you can wait NEC is also apparently releasing a new PA range of monitors all with IPS screens mid 2010 which may explain why the current 2490wuxi2 is so poor (interim solution?).
It is readily available in Europe and UK so you should have no problems obtaining this monitor (unlike in Aus)
