Well, that's it.

I will give to Dell that the customer support people I dealt with were generally pretty nice. However in the end there's not much in the way of a repair that could be done. So, I'm out an $800 monitor that was also my TV.

So, one more computer company off the list for now (I need to get a laptop for the fall). I just have this thing about if I get a lemon, then the company should be removed from consideration for more money from me. It would seem too much like rewarding them. Now it could be just random chance. Reviews on a lot of Dell products are pretty good, but at the same time those don't usually take into account extended use over a long period of time.

EDIT: I found a fairly cheap widescreen monitor on sale tonight that covers most of the bases of the old monitor for about $250CAD. So perhaps that's a bit of a silver lining.
