1920x1200 players! What do you use?

[Zonx]

Most complete sets support any reso and can be arange as you see fit. FetishNightfall and ThorUI are the most popular of these types.

ExtreameUI and Profit use a HUD arangement that may not support screens that wide. Unlike other UIs, these are designed to use the top and bottom of the screen for most stuff, something you may not like if you're already in widescreen. They may also provide a non-HUD option that I'm not aware of.
