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.
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.
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.
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.
