That is one thing CRT's do very well, and that is deep blacks. Look at the contrast ratio on monitors, that will be an indication as to how black they can go. Note that contrast measurement methods are rarely uniform and monitor manufacturers will skew the data. Also, the very high contrast ratio numbers I've seen are rarely accurate. I've only had one monitor go bad. I currently have a BenQ monitor (a BenQ G2400W 24") that I purchased from Newegg and I've been very impressed with it. The 22-inch Asus monitor I selected is better at only $10 more than the Hanns·G. What makes it better is two things, one, the monitor has a rebate that will drop the price to below the Hanns, and two, it has a faster refresh rate. As for the Acer, they can be good but 23 inches is an odd size for a monitor. I tend to trust Asus more than Acer from experience. The 24-inch Asus is also better than the 23-inch Acer for the same reasons. Unfortunately, the 24-inch Asus is the cheapest Newegg offers in the 24-inch range. If the 24-inch monitor costs too much, Asus does have a 23-inch model available. It has a $20 mail-in rebate which, if used, will make it the same price as the Acer, plus it has the 2ms refresh rate the other Asus monitors have.

. When buying monitors, make sure you have the best cable for your selected monitor. Using a traditional VGA cable for a monitor that can take HDMI or DVI is not a good idea. Also, monitors can be expensive to ship if purchased online. Check to see if there are any free shipping offers. Several of the monitors in all sizes at Newegg have these special offers. The shipping is important as any costs savings you think you are getting could be easily blown on shipping. Speaking as a fellow university student, you will appreciate the smaller size of an LCD. It makes it easier to move around.
