2048x1152 is the native res for the Samsung 2343BW and Dell 2309.
It works for me personally - I don't like larger panels as my eyes get tired constantly travelling across them at the distance I sit and that extra resolution over 1920 lets you compare two documents side by side at 100% in several different applications, whereas you can't at 1920.
