I currently have an older Acer 1600x1050 22" LCD monitor on my desktop which is where I do all my photo processing and viewing and such. Its an ok monitor for basic stuff but I've always found that photos I've had printed have colors and contrast that are drastically different than how they appear on this monitor. Granted, you can't expect a $100 monitor from 5 years ago to be calibrated from the factory and have 100% color accuracy but mine is pretty bad and it really shows with astro photos. So, I figured this would be a good time to get a new monitor given all the deals going on this season. The problem is I just can't figure out what to buy but I've narrowed it down to two choices.
1. Dell U2412m UltraSharp 24" Monitor - IPS monitor, 1920 x 1200 resolution, has very good image quality, no HDMI interface, and is about $250 right now

2. HP ZR2440W 24" Monitor - IPS, 1920 x 1200 resolution, known to have the best image quality in its class, has HDMI and many OSD controlls, about $350 right now

Basically, I'm wondering if the HP is worth it over the Dell. The Dell is very popular but slightly less better image quality, doesn't have an HDMI interface, and isn't as energy efficient (I'm a tree hugger). Also the HP comes with software that can be used for color calibration and other tools for getting an accurate image. So in a nutshell I'm wondering if the features the HP has is worth the extra $100 price tag over the Dell? Or is there another monitor under $400 that I should be looking at?
