I love this monitor. The image looks great, connectivity is great, VESA 100mm mounts are great, but the major WOW factor for me is the resolution. This is my first 1920x1200 resolution monitor and while the Dell U2415 is not the only 1920x1200 monitor out there, it is a great one.
Dell UltraSharp monitors have been fan favorites for years so I felt confident in purchasing one. I was tempted to go with the U2419H. I have used 16:9 1920x1080 monitors for years. I am not sure what made me eventually decided to go with the 1920x1200 resolution but I am happy I did. Like most people, I work on a computer all day. Having a few extra vertical pixels is wonderful. I will often use only part of the horizontal space on a screen for development but I maximize to use all of the vertical space. Its amazing what and extra 120 pixels will do.
