I have the Samsung CHG90, which is 3840x1080. It's literally a 4k TV cut in half horizontally. It enables me to very comfortably display three windows side by side. More than anything I have ever bought, this monitor has improved my productivity. They now have a newer version that is 5120x1440. The trade off is this monitor is very low res, about 100ppi. I don't know anything about how the various OSes render text. But I have found that by far, Ubuntu renders the text the best. Text in both OSX and Windows looks absolutely dreadful on this monitor, but Ubuntu is really quite pleasant. Which is not at all what I was expecting.
