Ok, after much discussion with BFG, and searching like a madman, I found a thread that seems have at least one person's experience with my dilemna...

BFG says that it MAY work, but that I'm pushing the limits of the DVI port at 1920x1600.
I THINK I can get 1920x1600 working for Windows, but now my concern is games.
I currently have the Samsung 213t which is native resolution of 1600x1200. If I run games on the 2405FPW at 1600x1200 (downsampled?) will I have the same kind of quality as on the Samsung?
In other words, I really want to have a good HL2 experience, and if the Samsung will do it better, I'll sell the Dell...
Any opinions? Should I just try it and "shut the f up?"
