Summary: The Dell 2407WFP has a bad power button, which appears to be an inherent design flaw in the product. Note that even under pretty light usage, it went bad. Do a google search for "2407WFP power button" and you'll gets lots of results showing others having the same problem. Otherwise, it has been a nice display, love the 24" size and 1920x1200 capability.
Summary: I loved this display until it stopped working. Owned it for 13 months before the power button broke and the monitor was stuck in the off position. A quick search will reveal that this is not an isolated incidence but clearly a design flaw. Keep looking and you'll find many posted workarounds. An apparently not so uncommon problem with the power button is that it somehow becomes loose and twists out of position.
Summary: Purchased a computer and 24" monitor direct from Dell. Got the computer in a week, the monitor never showed. A couple dozen emails, phone calls - one customer service rep actually asked me to call back when their systems came back online - and no monitor. Fed Ex finally admitted it was stolen off their truck - informed Dell, no monitor. They are the worst - online and offline - so if you have a problem you are on your own.
Summary: I have owned this display for eleven months. It is a nice product until it fails. Mine has failed twice. Then you are relegated to Dell Hell. I bought a five-year advanced exchange warranty for the product yet it is nearly impossible to enforce. Dell requires a SERVICE TAG to talk, email, or chat with them. Displays don't have them. You must call customer support, be subjected to long holds, and serviced by people who are unintelligible and incompetent.
