Too Big; Don't Buy. Well, unless you want it that big.
I'd be quite happy with 2304x1296. It just need to be a little taller than 1200 (1080 would never work out). I have 1920x1200 now and it's just a wee bit too small. It seems my only option is 2560x1600.
I also need the right spectrum. The monitors we bought from Dell at work really sucked because of the wavelengths chosen for each of the primary colors. They split wide apart. Nobody specs that, so there is no way to tell when buying online. I'm currently using an NEC MultiSync EA241WM. I had that at work, so I bought one for home, too. It has the spectrum that works best for me (colors don't split apart in my glasses).
