This is a very nice monitor that meets all my expectations.  It is replacing a 5 year old Samsung monitor that just failed in a triple monitors setup.  The older Samsung was a higher end one in the Samsung lineup at the time.  The U2412M is a little clearer and has good color.  The monitor is thinner and lighter and the base has a smaller footprint allowing me to set the monitor so it is further back on my desk reclaiming a few inches of desk space.  Since it is LED backlit it uses much less power than my other monitors.  I'm considering replacing the other monitors with U2412M monitors although it is hard to bite the bullet on that since the other monitors are working OK and they look fine next to each other for my purposes (data and charts).  I bought this at a higher price from one vendor on Amazon as they offered Amazon Prime shipping (overnight is $3.99) and I needed the monitor right away.  Unlike most other items on Amazon there is a huge difference in price between them and the other Amazon vendors - but I needed the monitor ASAP and even Dell themselves couldn't ship it overnight. 

Question: How is the monitor?
