I guess I should go ahead and share my setup.
This is a bit older now, I've upgraded my display since then...
The original setup had a DiamondPoint M55, but I'm now using the Dell Ultrasharp 1908FP display, in tandem with an Atlona AT-HD500 to scale to 1280x1024, and boy does it look clean with that. I still feel the DiamondPoint looks a bit better native, but the scale up is great.
