I've been looking to upgrade my monitor from 1440x900, and want to get 1920x1200. After looking around at some sites, i've noticed that 1920x1200 monitors are substantially more expensive than 1920x1080 monitors...why is that? It seems generally, 1920x1080 monitors are about $200, and 1920x1200 seem to be around $300. Why the 150% increase in price for 11% more pixels? Do you guys suggest any good 1920x1200 monitors?
