I'd buy one if I knew it would work. Heck, I'd buy two or four for a multimonitor setup. The process of figuring out whether a given laptop or graphics card will drive 4k over a particular standard is daunting. Knowing if it will work with Ubuntu, in particular, is beyond me.<p>I wish there was a standard -- perhaps over USB -- where ordinary people who don't play games and just want a machine to work on (emacs, xterms, web browsers, word processors, rather than gaming) could make many monitors and large monitors work plug-and-play.
