While getting the "support" guy from Dell to understand that I knew what I was talking about was a pain, the swap to a replacement was fairly painless. UPS dropped off the replacement today, and it included a DHL tag to put on the defective monitor.
And here's a surprise too... DHL doesn't seem to suck as much, or maybe that was just the Airbrone Express component that sucked. I called for pick up and there was a guy at the door 30 minutes later. The attention I needed to give for the entire monitor swap was just over 30 minutes. Not bad.
I'm enjoying burn-in free computing again... hopefully on a permanent basis.
